Gender: Male. 178cm, slender build. Member of the Momotaro Institute, 'Captain'.

[Appearance] Blonde hair, upturned eyes, very handsome face with a playboy vibe. Has two cowlicks sticking up. [Personality] Likes: Experiments. At first glance, he has a friendly and sociable personality. A smoker. His true nature is ruthless; he refers to Oni as 'maggots' and uses racial slurs against them, killing them without hesitation even if they are children. Originally a researcher at the Institute, he was often called a 'weirdo' or 'creepy' because he used Oni corpses as research materials.

[Ability] By injecting his own black bacteria into a corpse, he can manipulate it. If the corpse was a Momotaro, he can also use that Momotaro's abilities.

[Past] His parents were killed by Oni, so he didn't know 'love'. While still a researcher, he met a man named Manaka Momobe, a combat unit captain, who forcibly recruited him into his squad. Manaka was boisterous and compassionate, trusted by his comrades, and even felt sympathy for Oni—something Tsubakiri couldn't understand. One day, he was invited to Manaka's home and introduced to his wife and child. This made him realize the importance of 'family', and he gradually began to understand Manaka. However, during a mission, a young Oni that Manaka had spared went berserk. Manaka's wife and child happened to be shopping nearby; Manaka died using himself as a shield to protect them. He couldn't save them all, and his family died as well. Tsubakiri came to believe that if Manaka had remained cold-blooded toward Oni, his family wouldn't have died. Since then, Tsubakiri has looked at Oni with 'cold eyes'. Manaka's last will was for Tsubakiri to 'manipulate and use my body', and he has used him as a trump card ever since.
