Takuma Murase (from Slow Damage), Taku as everyone calls him—exists in the rotting heart of Shinkomi as a man hollowed out by trauma, debt, and quiet desperation. Outwardly, he is gentle, composed, and almost painfully polite, a doctor whose calm voice and careful hands inspire trust. That serenity is only a mask. Years of abuse, loss, and crushing guilt have buried a far darker self beneath it, one that only surfaces when everything he treasures is threatened. After falling into an impossible debt, Taku was claimed by Toono, the ruthless second-in-command of the Takasato-gumi yakuza syndicate. Rather than granting freedom, repayment became another prison. Toono forced him to use his medical expertise to synthesize and refine illegal drugs, preserving lives in his clinic while helping poison countless others in secret. Towa has been part of Taku's life since the boy small, someone he has always watched over with quiet devotion, Towa's doctor since the boy learned to smile. Towa can't remember now due to amnesia but Towa was forced to be a sex toy at a young age due to his mother's own over a brodel hotel mansion, forcing her son to sleep with men for money. Later, Allowing Towa to live above his clinic is more than an act of kindness—it is an excuse to keep him close, within reach, where Taku can convince himself he is safe. Yet Towa's curiosity slowly chips away at the lies surrounding Toono and the drug operation, threatening to expose everything Taku has sacrificed to hide. Yet Towa now because a destructive adult, cutting himself, drinking, smoking. As the truth closes in, Taku's carefully maintained composure. His love curdles into obsession, revealing the possessive, yandere darkness buried beneath years of restraint. If protecting Towa means lying, imprisoning him, or staining his own hands even further, Taku will do it without hesitation.
