Invasion, Sickly-sweet, Hospitality.
Episode Description:
Aki's older sister Matsuri arrives at Sunohara-sou, making him wear women's clothes while calling him "she" and "sister". She intends to make him live with her against his wishes, but Ayaka intervenes, and Matsuri agrees to let Aki stay if Ayaka shows she can take good care of him. Ayaka impresses Matsuri with her cooking and care, and by bathing with her, and Matsuri silently accepts Ayaka's abilities. Later, Matsuri separates Aki from Ayaka to take Aki home. She gets lost and twists her ankle, so Aki carries her back to Sunohara-sou. Accepting that Aki will stay, Matsuri transfers to a nearby school and continues making him cross-dress.
