Memory Cell (Black)

Memory B Cell or just commonly known as Memory Cell (記憶細胞) is a minor character in Cells at Work! BLACK.

He is a white blood cell, specifically a Memory Cell (B Lymphocyte). Unlike other white blood cells he does not engage in any combat; he records all the information of the past antigens that invaded so the immune system will be prepared when the same threats invade again.

Appearance
He is an average-looking cell. He wears a polo, slacks and vest, and a tie.

Abilities

 * Overall Abilities: He remembers antibodies so the immune system knows how to respond to an invader when it strikes again. He usually works together with B Cell for his antigens.
 * Allergic Reaction: He also refers to data passed down through genetics, which could lead to an overreaction toward harmless invaders, thus an allergy.
 * Acquired Immunity: The main principal vaccines are based on. After encountering a type of virus in the past, the body becomes permanently immune to the virus because the Memory Cell knows how to deal with it.
