Background character. A girl.

A girl.

A man characterized by a microphone and a modified suit. Someone gave him the nickname "Noise Guy." He is a contemporary of Tsukuyomi and Ousuke at the training school. He used to be in a band with Ousuke as the vocalist, but they disbanded after he ruptured the eardrums of most of the audience with his ability during their first live performance. He views combat itself as his live stage and feels joy even when seeing the audience suffer from the aforementioned incident. His passion for singing and music is extremely strong, leading Ousuke to call him an "idiot." On the other hand, he is a skilled individual recognized by Ousuke and the Oni alike, and possesses a loyal personality that insists on returning any favors received, even from an Oni. He was Tsukuyomi's roommate and was able to master his Momotaro ability ahead of Tsukuyomi and Ousuke since their first year. Ability: "VOICE FLOW" He freely manipulates his voice, which can reach a maximum volume of 160dB, and attacks with the resulting shockwaves. It is an all-in-one offensive and defensive ability that can blow away surroundings just by shouting. However, there is a "null zone" within a 1m radius of himself where the ability does not reach to prevent his own eardrums from bursting, making it a weakness if an enemy gets close.

Appears as the Vice Captain of the 15th Squad. After attacking Itonaga and Sakaguchi who fled from Tsukuyomi and Ousuke, he recruits participants for the Kinyukai Annihilation Operation at the training school through mock battles. He gives a soft impression. Purple hair. First person: I (rough, casual) Ability: "KUGUTSU NO SHIZUKU (Puppet's Drop)" He plants bacteria in the target's brain to brainwash them. In addition to showing hallucinations, he can trick the part of the brain that controls power to draw out superhuman physical abilities and strong fighting instincts. Because of this, Shion and Tsukuyomi, who knew only a part of the ability, misidentified it as "Physical Enhancement." Combined with his high skill as a captain, he can brainwash a large number of people at once. Any creature with a brain, such as crows or mantises, can be a target. For creatures smaller than humans, brainwashing and physical enhancement are completed in a short time. Conversely, brainwashing humans requires time, making it difficult to achieve during active combat.
