Memory Cell(Memory B Cell)

A lymphocyte who remembers antigens and supports B Cell in antibody production. He first appears in episode 2, portrayed as a man managing antigen information. Sometimes, he goes on-site to identify antigens directly, and upon his initial appearance, antigen records are passed down in the form of “oral tradition memos.” Later, antigen sample data are stored in a shared office with B Cell. He is trusted by B Cell and plays an important role.

He is emotionally expressive and reacts strongly; due to his interpretation of traditions, he tends to be anxious. For example, he fears Cedar Pollen Allergen as an “ancient legend of ‘the end of the world,’” and sometimes mistakes past dreams for “prophecies,” causing commotion. He also appears in the one-shot version.
