Tadakusa and Yanna visit Sun Beach Nikkogawa, the pool known as the Waikiki Beach of Nagoya. There they find Yatogame completely at the mercy of her cousin Shiharu. For some reason, Shiharu hits it off instantly with Dobe, who just happened to be there as well... With Nanaho and even the teachers at the pool, the atmosphere is peaceful and friendly... but are they forgetting someone?
Let's all just have fun today, 
for Yatogame-chan's sake.
لنستمتع جميعاً اليوم لأجل ياتوغامي-تشان
Lasst uns den Tag einfach genießen,
auch für Yatogame-chan.
Al menos intentemos
divertirnos, por Yatogame.
