YMMV / Dawn Tsumetai Te

• Complete Monster: The seemingly affable, mysterious Doctor is the actual creator of the Nightshift virus. Having created it accidentally, the Doctor tried to sell it for profit, accidentally infecting protagonist Takeshi Nagasawa and liberating the virus. Allowing the virus to spread due to scientific curiosity, the Doctor saves Nagasawa's life in order to blackmail him into helping him to hunt other infectees. After the infectees start to develop conciousness, the Doctor blackmails Akemi, another Nightshift infected, into helping him to capture the rational ones in order to create a drug that destroy their conciousness by promising to save her best friend. When Akemi betrays him, the Doctor reveals that he killed said best friend, asking her if she wants to see her body parts before killing her after she attacks him. Despite his charismatic behavior, the Doctor is a selfish scientist willing to betray everyone in order to benefit himself, with every positive act of him being motivated only for his own interest.
