My Companion Insisted I Wash My Hands of the Past - Reviews

What I love about this worldbuilding is how seamlessly it layers the dangerous with the domestic. We're talking about people with supernatural abilities, criminal records, assassination attempts, and Port Mafia connections — and they're also washing fruit, opening a milk tea shop, and wrapping New Year's gifts. The dessert shop detail is genuinely brilliant worldbuilding. Kikuye does MARKET RESEARCH. She considers the skill requirements, talks to the shop owner, pivots from complex desserts to milk tea because it's more practical. This isn't just flavor text — it's a character who treats running a business with the same strategic mindset she applies to everything else. And Xiao Zhi suggesting "Extra Spicy Milk Tea" because spice is pain, not taste, to someone who's numb to danger — that's worldbuilding through character psychology. The detective agency run by Ginro and Ranpo operating in a gray area between police and army is such a smart addition to the Yokohama underworld ecosystem. It gives the story institutional depth — there are rules, there are power structures, there are people who exist between the law and chaos. And Chuuya working for them, earning money to pay off his debt, creates this whole ecosystem of interdependent relationships. The New Year's Eve gathering at the end — the shop owner's home, the awkward couple-vibe tensions, Ranpo being excited, Silver Wolf reluctantly coming along — it paints this picture of a chosen family so ordinary and warm that it almost hurts, especially when you remember what these people are capable of.

The pacing here is honestly insane. We go from 'I almost got killed' to 'let's be roommates and buy cat mugs' across four chapters and it works because the author never lets the tension sit still. Chapter 4 starts with the most dangerous moment—two killers in a room, one deciding whether to retire—and immediately pivots to domestic logistics. Who sleeps where, who takes the softer blanket, who does the dishes. The shift from life-or-death to 'you're on trash duty' is so abrupt it's hilarious, and it keeps you reading because you never know which tone is coming next. Then there's this beautiful rhythm of tension and release. She stares at him in the dark, her combat instincts flaring, he asks if something's wrong, and then drops the 'I will protect you' line. Boom. Released. Then immediately—next morning, convenience store, restocking shelves. The mundane snaps back in like a rubber band. The cliffhanger energy is more subtle here. It's not 'will she live?' but 'will this weird domestic arrangement actually hold?' And the author knows exactly when to pull the thread. Like when she brings up the conglomerate still being alive and Oda immediately catches the hint. That's a pacing masterclass—raising the stakes without breaking the cozy mood. Some parts drag slightly (the internal monologue about retirement funds gets long), but honestly I was too invested to skip anything.

I need to talk about this one moment because it destroyed me. Oda Sakunosuke — the boy who has watched himself die thousands of times, who speaks in flat, deadpan sentences — looks at Kikuye and Chuuya and says, with absolutely zero emotional inflection: "I feel a little jealous." And then he can't even explain WHY. "There should be a reason... but none of the reasons I can think of feel sufficient. So I don't know." Do you understand what that means? This is a person who can predict five seconds into the future with perfect accuracy, who has calculated every possible outcome of every interaction, and there is literally a gap in his understanding that his ability CANNOT fill. He knows what will happen, but he doesn't know what he FEELS. That is devastating. And Kikuye's reaction — she pokes his cheek, celebrates her success silently, then tells him that all those possible futures aren't the future and that right now he's just sitting there talking to her. She grounds him. Not with grand declarations, not with emotional speeches, but with the simplest possible truth: you are alive, you are here, this moment is real. The romantic tension between them is absolutely simmering under the surface but neither character seems to fully recognize it. Kikuye explicitly thinks about how she'd refuse a confession, how she sees romance as dangerous because of Momiji's story, and yet she's the one who reaches out first, who closes the distance, who insists on knowing what Oda was about to say. And Oda — Oda hesitates. For a character who has seen every possible future, the one thing he cannot predict is what he wants to say in the present. That hesitation, that closed mouth, that "it's nothing" — it's the most romantic thing in this entire chapter.

Okay so I need to talk about the face-pinching scene because I literally cannot stop thinking about it. This whole dynamic between Kii and Oda is so weirdly wholesome and I'm here for it. On the surface it's just this chaotic energy from Kii—she's clearly flustered about something (anger? attachment? she won't admit which) and her solution is to physically grab Oda's face. But the way Oda reacts is what kills me. He doesn't fight back. He doesn't even seem that surprised. He just sits there, hand covering his face, looking genuinely confused like his precognition somehow failed to predict THIS of all things. And then the follow-up conversation? Chef's kiss. "Why did you pinch my face?" — asked with zero drama, zero accusation, just genuine curiosity. And Kii's internal panic is so relatable. She literally thinks about how asking "why not" would make her sound like a creepy person. The self-awareness! But what really gets me is that Oda says "please don't do that next time" — and the fact that he uses PLEASE. This is a guy who can probably see the future and still asks politely. That's not weakness, that's a whole different level of emotional maturity. Also the whole "are we companions?" moment in Chapter 11? Kii freezing up over that question is the most honest character moment in the entire passage. She's overthinking friendship labels like it's a bomb defusal. And Oda's just sitting there like "why is that a question?" — bro, you're the one who brought it up! The tension between them is everything. She's clearly afraid of him (or at least acknowledges it), but also completely unafraid in practice. That contradiction is the whole relationship in a nutshell.

The stakes in these chapters are deceptively simple on the surface—two kids sharing an apartment, working at a convenience store—but underneath there's this constant undercurrent of danger that never fully goes away. The external conflict is clear: the conglomerate that hired Oda to kill the protagonist is still alive and won't forget a failed hit. She literally says this to his face: 'you know that conglomerate I got involved with hasn't gone under yet, right?' And his response—offering to protect her—means he's now taking on a threat he could have just walked away from. But the internal conflict is where this really gets interesting. Oda is trying to become someone who doesn't kill, but the protagonist is already planning around the possibility that she'll need to. She's not actually retiring; she's just changing tactics. And Oda? He's performing a new identity. 'I just wanted to know how the story ended… If anything, it might have made me a little restless.' That line about the novel making him restless—what does that mean for someone trying to build a new life? The most tense moment isn't an action scene. It's lying in the dark, one meter apart, both of them aware that the other could end their life at any moment, and choosing not to. That's the real stakes here—not just survival, but whether these two can actually trust each other enough to let their guard down. And honestly? I'm terrified for them. Because the moment they do relax is the moment something will go wrong.

Okay, let me just say this out loud because it genuinely surprised me: the entire Chuuya subplot is held together by a five-million-yen debt that somehow becomes the most important relationship-building tool in the book. Think about it. Kikuye lends him money, sets absurd terms, and instead of it being some exploitative thing, it becomes the thread that stitches him into their found family. And Oda — cold, detached Oda — gets JEALOUS over it. Not jealous that Chuuya is close to Kikuye, but jealous that a KID owes her money. That is such a bizarre, specific emotion to have, and it completely recontextualizes everything about how these characters bond. The plot structure here is really clever because it operates on two levels. On the surface, it's a debt collection story with side jobs and a dessert shop opening. But underneath, every transaction is actually an emotional transaction. When Kikuye says she values information more than money — that's not just a cool line, that's her survival philosophy. And when she reveals her ability's weakness (emotional dependency), it mirrors Oda's weakness (emotional numbness from seeing his own death repeatedly). Two broken people who can't function normally, finding each other through criminal enterprises and shared trauma. The plot doesn't just move forward — it spirals inward, deeper into who these people actually are.

I need to talk about the atmosphere in these chapters because WOW. The author has this incredible ability to make you feel the cramped intimacy of a one-room apartment shared by two killers who are figuring out how to coexist. The moonlight scene in Chapter 4 is pure cinema. 'Moonlight streamed in through the window, and thanks to his professional training, I could see clearly and met his deep blue eyes.' That line. The way the narrator describes instinctively going into combat mode even while lying in bed next to someone—every muscle tensed, hands clenched under the blanket. This is a person who CANNOT relax, and the setting amplifies that so perfectly. Then you have the convenience store scenes. The manager teasing about boyfriends, the leftover bento situation, hiding two pork curry meals like a little criminal. It's these small domestic details that make the world feel lived-in. Yokohama's underworld exists in the background, but the real story happens in tiny spaces—a futon on tatami, a store shelf, a shared meal. The expired juice detail also stuck with me. He drinks it without complaint. That's such a small thing but it tells you everything about who this character is. Not delicate, not picky, just... present. The worldbuilding here is all in the details, not in exposition dumps.

Let me just say this upfront: I did not expect to feel anything from a story about two teenage assassins, and yet here I am emotionally compromised. The emotional journey in these first seven chapters is surprisingly complex because it operates on two levels simultaneously. On the surface, it's a comedic buddy story about two mismatched people forced together. But underneath, there's this profound loneliness that both characters carry, and it's devastating. Tsuboi's loneliness is loud and performative—they complain about having no friends, they're jealous of Oda's normalcy, they're constantly anxious about being abandoned or betrayed. But Oda's loneliness is quiet and far more painful. When he says "Being able to have your own home—that alone is impressive," he's not just making small talk. He's revealing that he has never had a place to call his own. He's never had anyone to share it with. He's been a killer his entire life with no roots, no connections, no sense of belonging. And yet, the way these two interact is so tender in its own weird way. Oda follows Tsuboi home not because he's threatening them, but because he genuinely doesn't know where else to go. Tsuboi offers him expired juice not out of kindness but out of self-preservation, but the gesture itself is almost domestic. Two broken kids in a cheap apartment near the harbor, trying to figure out what comes next. The moment that got me the most was when Oda sat on the steps and talked about the novel he read—the one where the protagonist was a killer who stopped killing but the ending was torn out. He wanted to know why. And now he's going to write the ending himself. There's something incredibly hopeful about that. This boy who has never known love or home or purpose is going to try to understand humanity through literature. He's not just running from his past—he's reaching toward something new. And Tsuboi, who has spent their whole life being afraid, is slowly realizing that maybe, just maybe, they don't have to be alone anymore.

"I'm already used to it. After all, both the name and the nature of my ability are overflowing with that edgy, over-the-top 'chuunibyou' vibe." This line right here sets the tone for everything. The worldbuilding in this story is so clever because it doesn't stop at "people have special abilities in Yokohama." No, it goes deeper into how that affects everyday life, social dynamics, and even the most mundane things like where you choose to rent an apartment. Let me talk about Tsuboi's apartment because the description is genuinely vivid. It's on the second floor of a low-rise apartment near the harbor—cheap materials, lightweight steel construction, minimal maintenance fees. The kind of place where neighbors are people you barely see. But here's the genius detail: most tenants are low-level port Mafia personnel, so disappearing for a while and coming back raises no eyebrows. The manager only shows up to collect rent. This is a world where criminal activity is so normalized that your landlord literally doesn't care what you do as long as you pay on time. And the harbor setting itself is atmospheric. You can almost smell the salt air, see the sunset reflecting off the water, hear the distant sounds of ships. When Oda and Tsuboi sit on the steps watching the sunset, the scene shifts from tense confrontation to something almost peaceful. The wind tousling Oda's reddish-brown hair, the golden light—it's cinematic in a way that makes you forget these two were literally just trying to kill each other an hour ago. The world feels alive because it's not just a backdrop. It's a character in itself. Yokohama has its own economy, its own hierarchy, its own unspoken rules. And the fact that there's "more than enough work" for assassins here, with an employment rate second only to Hakata, tells us so much about this world without any exposition dumps.

I need to address the narrative voice because it is absolutely phenomenal and I will not be silenced. Tsuboi's internal monologue is a masterpiece of comedic timing. The way they go from professional assassin mode to full-blown panic attack in the span of three paragraphs is incredible. Let me give you some examples because this text is gold: "Being called that stupid codename by my enemy right before dying isn't just embarrassing—it's downright humiliating!" Then immediately after: "Choking back tears, I muttered, 'Okay... can you let go of me now?'" "I'm still growing—what if this affects my height?!" This person is literally facing their potential death and their first concern is whether being pinned down will stunt their growth. The priorities are immaculate. And the dialogue itself is so natural and distinct between the two characters. Oda speaks in short, flat statements with zero emotional inflection, while Tsuboi's internal voice is a whirlwind of exclamation points and rhetorical questions. When Oda says "I want to write novels" with the same energy as someone saying "I want a glass of water," the comedic contrast is perfect. The author also uses dialogue tags brilliantly. Notice how Oda rarely has any emotional descriptors attached to his speech? Just "he said matter-of-factly" or "in his usual measured tone." Meanwhile, Tsuboi's narration is dripping with emotion. This isn't just good writing—it's character development through voice alone. And can we talk about the line "Ji Jiujiang"? The fact that Oda mispronounces or anglicizes Tsuboi's name and Tsuboi just goes along with it because they're too terrified to correct him in that moment? That's a tiny detail that tells you everything about their power dynamic.

The symbolic architecture of these chapters is remarkably sophisticated, built around two opposing abilities that represent two opposing ways of existing in the world. Kikuye's ability requires emotional volatility — she becomes invincible when her feelings spike, when she channels shonen protagonist energy. But it's tied to performance, to drama, to maintaining a state of heightened emotion. Her "black wings" are weapons, symbiotic, flexible — they represent her adaptability, her willingness to become whatever the situation demands. She is chaos incarnate, surviving through intensity. Oda's ability is the exact opposite. Five seconds of precognition. Not five, not six. Five. It's precise, limited, clinical. He has seen his own death thousands of times and grown numb. His ability doesn't change the future — it only shows it. He is trapped in foresight, unable to act with conviction because he has already witnessed every possible outcome. The debt itself is a powerful symbol. Money as emotional currency — Kikuye lending Chuuya five million yen is actually investing in his future, in his belonging. The shop owner's family dying because of the Port Mafia connects personal loss to systemic violence. The milk tea shop represents the desire for normalcy, for creating something sweet in a world that has given these characters nothing but pain. And that final scene — Oda opening his mouth to say something, then closing it, saying "it's nothing" — is the ultimate symbol of the story's central tension: these people who have seen death, betrayal, and loss are learning to live in the present, to value the moment over the prediction, to choose connection over calculation. The only future that matters is the one they're building together, one cup of milk tea at a time.

There's something deeply symbolic about Tsuboi's ability called "Jet-Black Wings" that I can't stop thinking about. On the surface, it's a chuunibyou power with dramatic chanting requirements and literal prop wings that can't even fly. But think about what wings represent—they're supposed to be about freedom, transcendence, rising above the mundane world. And Tsuboi's wings are literally just props that help them jump off surfaces. They can't fly. They can only help them move through the world in a slightly more dramatic way. Isn't that exactly what Tsuboi's life is? They're an assassin trying to escape their circumstances, trying to rise above the bloody path they've carved, but they're still grounded. Still stuck. Still using their "wings"—their ability, their codename—to survive rather than to truly be free. And then there's the name itself. Tsuboi is jealous of Oda because he uses his real name openly while Tsuboi hides behind a codename. But what does a codename represent? It's a mask. It's the part of yourself you show to the world because the real you feels too vulnerable, too ordinary, too embarrassing. Tsuboi doesn't want "Jet-Black Wings" invading their life outside of work. They want to be just Tsuboi Kikue, a normal fifteen-year-old. But the codename has become so central to their identity that they can't separate the two. Oda, on the other hand, has already shed his old identity. He's literally quitting being a killer to become a novelist. He's trading one mask for another, but at least he's aware of it. His motivation—wanting to understand what it means for humans to live so he can write about it—is almost philosophical. He's not running from his past; he's trying to transcend it. The contrast between these two approaches to identity is the thematic heart of the story.
