Honest Review
Found this one has potential, feels a lot like Sword Art Online. (A very hard to read version of it.)
The Good: Character classes are unique and it is nice to see an MC that isn't 100% righteous for once.
The Bad: Hard to follow... it jumps around a lot with little to no indication. I found the world setting kind of convoluted and some of the situations to be pointless. It feels like a lot of this is filler content so far because I really only care about Shiro and people he interacts with.
The Neutral: Objectively describing someone as "sexy" leaves it open to interpretation, that's not a bad thing by itself, but who thinks it is sexy? (i.e. the observers, the characters, the readers, NPCs?) Maybe I missed it, but why are they stuck in the world?
Maybe add a note that senshi = warrior and the significance of it so people don't think "WTF are senshis? Sounds like sushi!" or something like that. (Assuming that is what you meant it to be)
Feel free to review back and I'll add you on Line if you would like editing help.
