Meisa is the drummer of Zephyr, a boy band formed in the slums of near-future Tokyo before a devastating war forced them to abandon music. With black hair and a quiet presence, his role remains anchored to maintaining the band’s rhythmic pulse, though specifics of his appearance and personality are undefined. The narrative frames him within the collective resilience of Zephyr as they navigate survival in a fractured cityscape, their shared history marked by loss and the abrupt end of their artistic pursuits. While the story explores the group’s adaptation to postwar hardships, Meisa’s individual choices, past, and inner world are not expanded upon. His interactions with fellow members and personal evolution remain unexplored, leaving his identity inextricable from his function as the band’s percussive anchor. No supplemental materials or storylines delve deeper into his relationships, ambitions, or potential growth beyond this collective context.
