Three standalone stories pull back the curtain on the lives of the girls surrounding Takaaki, with each episode centered on a different character. In the first, Ilfa, the first humanoid robot Sango-chan has built, needs real experience with people, so she trains as a maid in the Kousaka household, serving the camera-obsessed, maid-loving Yuuji and his stern older sister Tamaki. The second follows a beach outing where Takaaki brings along Komaki Ikuno, Manaka's frail younger sister, who agrees reluctantly because she suspects he is dating Manaka and wants to keep watch over her. In the last, Takaaki and the shy class representative Kusugawa Sasara have their school festival plans ready, until student council president Maaryan, Sasara's only friend, reworks them the night before with plenty of odd, racy additions. The mix of comedy, drama and romance keeps each episode light while giving its heroine room to shine.
