Kotaro Lives Alone

A strange four-year-old boy named Kotaro moves into Shimizu Apartment all on his own. He doesn't seem to have any parents or family around.

Karino figures out why Kotaro talks the way he does: he's copying Tonosaman, his favorite cartoon character from a show that's about to end.

When he sees someone handing out free balloons, Kotaro tries to collect as many as he can. But there's a reason he wants so many balloons.

Kotaro's friend Kakeru has a maid who takes care of everything for him, so Kotaro decides to show Kakeru how to do things for himself.

For some reason, Kotaro is very particular about his tissues. He wants expensive, soft ones because they're "sweet." Later, Karino figures out why.

A man named Aota moves into the building for a month. When he asks Kotaro to be his friend, Karino gets suspicious — and a little jealous.
