Every Day When This Kitty Wakes Up, I’m in the Demon Lord’s Bed

Bai Xiaonian, the former Demon Lord of the realm, is reborn into the body of a tiny, powerless white kitten. His previous life ended with his throne stolen by his rival, Chong Yin, a man Bai Xiaonian once knew as a frivolous noble who spent his days drinking and tending flowers. Upon waking in this new form, Bai Xiaonian is immediately captured by demon soldiers tasked with collecting spirit beasts for the new Demon Lord’s cultivation. Forced into a cage with larger beasts, he endures humiliation as the animals treat him like a toy, unaware that the fragile creature contains the soul of their former ruler. The kitten is delivered to the Demon Palace, destined to be consumed, but Bai Xiaonian refuses to accept this fate. Using his intimate knowledge of the palace’s layout from his time as lord, he escapes the Beast Garden and infiltrates the main hall, hoping to assassinate Chong Yin while the man is bathing.

The assassination attempt fails when Bai Xiaonian falls into the water, a disaster for a cat, and is pulled from the pool by Chong Yin. Instead of killing the intruder, Chong Yin is intrigued by the kitten’s unusual intelligence and defiant temper, which remind him of his old rival. He names the cat Xiao Niangao and keeps it as a pet, a decision that shocks his subordinates. Bai Xiaonian, now trapped in a helpless body, must navigate life under his enemy’s roof. He struggles with his new physical limitations, particularly his fear of water and his inability to communicate his human thoughts. Despite his hatred for Chong Yin, he is forced to rely on the Demon Lord for survival, leading to a series of comedic and tense interactions where Bai Xiaonian’s attempts at revenge are misinterpreted as playful or cute behavior.

As Bai Xiaonian settles into the palace, he discovers that Chong Yin has changed significantly over the past two hundred years. The man is now cold, ruthless, and obsessively clean, ruling the Demon Realm with an iron fist. Bai Xiaonian also learns that Chong Yin has taken concubines, including Consort Yi, which infuriates him given his own past preferences and his complicated history with the man. The conflict escalates when a jealous cook poisons a dried fish given to Bai Xiaonian, an act of sabotage driven by resentment toward the kitten’s favored status. Chong Yin discovers the poisoning and punishes the cook severely, revealing a protective side toward the cat that Bai Xiaonian finds both annoying and necessary for his survival. The incident forces Bai Xiaonian to confront the reality that he cannot reclaim his power in his current state and must bide his time.

The story follows Bai Xiaonian’s attempts to regain his footing while hiding his true identity. He uses his knowledge of palace secrets and Chong Yin’s habits to manipulate situations to his advantage, though his small size often undermines his authority. His interactions with Chong Yin become increasingly complex, blending hostility with an undeniable, albeit reluctant, dependency. Bai Xiaonian’s goal remains clear: to recover his strength, expose Chong Yin’s true nature, and reclaim the throne. However, the path forward is fraught with danger, as he must contend with internal palace politics, the suspicion of his former subordinates who now serve Chong Yin, and the ever-present threat of his enemy’s power. The narrative sets the stage for a long game of espionage and cultivation, where the former Demon Lord must navigate a world that no longer recognizes him, all while living under the nose of the man who stole his life.
