Qi is a 25-year-old Chinese male, formerly a herbal pharmacist, known for his laziness and expert knowledge of plants, drugs, and poisons. Although frequently called a "loser" by both friends and strangers, he has a subtle sense of justice hidden beneath his laid-back demeanor.
Qi is a young adult male, often mistaken for being older due to his tired expression and attitude.
His prison number is 71, and his badge reads 0571; after his cell transfer during repairs, his badge reads 0471.
Qi belongs to the inmates of Block 5, Cell 8, and later temporarily moves to Block 4, Cell 10.

He seems unconcerned about how others view him and is often teased or insulted for his lack of motivation.
Despite his disinterest in most things, his love for plants and chemistry is genuine.
He feels little guilt about his past actions, except when asked to create narcotics, which offends his limited sense of right and wrong.
Qi started his career as a herbal pharmacist, developing a remarkable expertise in medicinal plants and toxic substances.
He was previously involved with a mafia syndicate, where he made poisons for the boss, Hachiman, but refused to manufacture drugs when ordered, showing a subtle moral streak.

His talents allow him to concoct remedies or toxins from virtually any plant material.
He has a long record of producing combat poisons for syndicate use.
Qi gets along with Inori Hakkai, who shares a similarly slovenly lifestyle.
His relationships with Liang and Upa are complicated, colored by their shared mafia past and his habit of skipping workouts.

Hachiman, his old boss, once forced Qi to create dangerous substances for criminal purposes.
Qi is ironically called "old man" despite being 25, making him younger than Samon Gokuu.

“I don't care what you call me, unless it's to make drugs—I won't.”
