EPISODIUM
As they enter summer vacation, some volunteer work pops up at Usagi's school. With her classmate Naru, Usagi, Ami, and Makoto help watching over kids at a children's home. While she doesn't know how to handle the kids, Usagi's got a particular scheme in mind. Without telling Makoto, she calls up Motoki and leaves the two alone. Not knowing anything, Makoto carries the children's dirty clothes to the backyard.
...where Motoki has just arrived.
