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".
Only that perv of a girl is left.
Nur noch diese Perverse übrig.
Solo falta esa loca.
Solo falta esa loca.
Plus que l’autre perverse.
Manca solo quella pervertita.
Só sobrou aquela tarada.
