Description
Momotaro Onzai is a member of the idol unit B-Project and belongs to its sub-unit MooNs, alongside Hikaru Osari, Tatsuhiro Nome, Kazuna Masunaga, and Mikado Sekimura. He was raised in an urban environment and carries himself with a cool, composed demeanor. Because he does not express his emotions openly, he is often misunderstood by those around him, but he is a sincere and serious person who faithfully keeps his promises. He possesses a sharp sixth sense and occasionally makes eerie or mysterious remarks. He is also able to see spirits, a trait that is revealed later in the series.

Personality-wise, Momotaro is stoic and appears blunt at first, yet he has a caring side and is skilled at reading the subtleties of other people. He tends to support his fellow group members from the background rather than seeking the spotlight. Despite his reserved exterior, he enjoys teasing Hikaru, one of his MooNs group mates, whenever the opportunity arises. He has no strong prejudices or dislikes and accepts others as they are, while also maintaining a bird's-eye view of himself.

His motivations are rooted in his commitment to his group and his responsibility as an idol. He takes his obligations seriously and works to uphold the trust placed in him by his fans and colleagues. Within the story, Momotaro plays a steady, grounding role in B-Project, offering subtle guidance and quiet reliability. His relationships with the other members of MooNs are close, and he interacts with the wider B-Project cast through joint activities and performances.

Physically, Momotaro has a lean and graceful build with an average height. His hair is cut in a short bob, parted in the middle with a single strand falling between his eyes. A notable physical trait is his heterochromia: one eye is red and the other is blue. His birthday is September 22, and he is 169 centimeters tall, weighing 51 kilograms, with blood type AB.

In terms of development, Momotaro gradually opens up more to those around him as the series progresses, showing that his cool exterior conceals a compassionate and dependable nature. His ability to perceive supernatural elements adds an unusual layer to his character, setting him apart from many of his fellow idols. While he does not possess flashy or overtly dramatic abilities, his intuitive sense, loyalty, and capacity to support others from the shadows are his defining strengths.
