Sonoa gets drunk and ends up living at Tachibanakan. Yuu gets everyone to have a welcome party for Sonoa, so they meet by the riverside in appropriate outfits. Yuu has water guns waiting for them, and has everyone enter a "Water Gun Survival Game".
I'm not letting you go see-through.

No se te transparentará.
Ton soutien-gorge…
Nessuno vedrà il tuo reggiseno!
Não vou deixar que seu
sutiã fique transparente.
