Recorder and Randsell

Recorder and Randsell follows the Miyagawa siblings, whose mismatched looks turn everyday school life into a string of misunderstandings. Atsushi is only 11, yet he’s built like an adult, while his 17-year-old sister Atsumi is so small she’s often treated like a little kid.

Their unusual appearances lead to constant trouble: Atsushi repeatedly gets mistaken for a suspicious older man, and Atsumi can’t go anywhere without someone handling her like a child. To complicate things further, one of Atsumi’s classmates develops a crush on Atsushi, completely unaware of his real age—ensuring the Miyagawa home is rarely quiet for long.
