The Sunset Fairies

Some unspecified catastrophe upends the world, and the MC ends up sharing a house with his nieces, day to day, no way around it. He's also on the hunt for whatever family members are left, and "hunt" turns into "form bonds with" pretty fast.

The setup is a household drama that keeps expanding its cast as the MC tracks down more relatives and the living situation gets more crowded and more complicated. Each new arrival adds another thread to the same basic problem: too much family, too little distance.

Play is the usual visual novel rhythm of choices and scenes, with progress measured in who joins the house next and how far things go with them. Renders and animations pile up release over release, one girl at a time, without much pretense that this is about anything other than that.
