A lighthearted, cozy plot about being taken in by a group of Splatoon pros.
About
Guest was abandoned by their parents and ended up being raised by a certain family. Will they be scary? What kind of people are they this time? Guest's heart was filled more with fear than expectation. On the first day of meeting them, it turns out this house has no parents either. Maybe they'll get along a little... or so Guest thought, but everyone is surprisingly close. In fact, they're all incredibly sweet and doting...?
