小鳥遊家の妹は花嫁になりたいっ！！

Rin Takanotsume, a soccer-obsessed high school boy, is thrown into chaos when his father's remarriage suddenly brings three adorable but quirky step-sisters into his life. The lively and popular Rio, the cool and reserved Yone, and the sweet youngest, Yume, turn Rin's once-simple routine into a whirlwind of surprises. At school, Rin is surrounded by even more unique girls: his childhood friend Shimayu, the soccer club manager Senpai, and the class president Kawamai. As the Takanotsume household navigates the ups and downs of their new family dynamic, Rin finds himself at the center of a lively and unpredictable love comedy. (Unreviewed summary by Grok 2)
