Natsuki sets his heart on creating a tidal power generator that utilizes the ebb and flow of the ocean's tides. He dives back into the ocean to find some materials and salvages some resin from the ruins of Ryuuji's family's factory. As soon as he gets back he gets to work. As they are working, Natsuki and Ryuuji exchange heated opinions over how the generator should be built. Atri intervenes and the two guys become closer friends. Meanwhile, a suspicious-looking character peeks at them from outside of the school....
Not only that! I have a precise 
sense of taste just like humans do!
ليس ذلك فحسب. لديّ حسّ تذوُّق
!دقيق تماماً مثل البشر
Und mein Geschmackssinn ist genauso
ausgefeilt wie der eines Menschen!
Y tengo un gusto
tan delicado como el humano.
Y tengo un gusto
tan delicado como el humano.
En outre, tout comme vous,
je possède des capteurs gustatifs.
Non solo, ho anche un senso del gusto
simile a quello degli umani!
Além disso, o meu paladar
é tão delicado quanto o humano!
У меня даже есть вкусовые рецепторы,
прямо как у людей!
แถมยังรับรสได้ละเอียดอ่อน
เหมือนกับมนุษย์ด้วยค่ะ
