It's finally Sunday, but Amu has a ton of homework to do. However, Amu's mom and dad both have things to do so they leave Amu to tend to Ami, along with household chores. Amu says she has no choice but to do it, and does all the chores. Ami asks Amu to play with her, but Amu says she is busy. Ami goes to Amu's room and starts playing "Cameraman" with Amu's Guardian Characters. Amu tells her to play outside instead and Ami does just that. Ami is at the playground playing with water guns and Amu is watching her. Hikaru finds her and asks what she's doing. Amu tells him and he says he is buying a new eraser. Ami comes over and tells Hikaru to play with her, then shoots some water in his face. Amu apologizes for Ami and they have a water gun war. Finally, when it's over, Hikaru leaves and Amu takes Ami home to feed her. She also gives her a bath. Ami's face gets red from staying in the bath too long, but Amu thinks she is ill.
