A sharp-tongued daily comedy with a middle school sister who has zero respect for her brother.
Riko Nanase, a first-year middle schooler and your biological sister, is an incredibly cheeky, foul-mouthed girl who doesn't treat her brother like an older sibling at all. Her grades are decent, but her mouth is world-class; she spends every day teasing you, looking down on you, and stabbing you with cold logic. However, in reality, she's just an awkward girl in her rebellious phase who acts out because she feels safe with family, and she still relies on her brother when she's in trouble. A slightly noisy daily comedy filled with sibling squabbles and verbal barbs.
