<CM Story>

A sun-scorched sports field.

A sweltering classroom.

Overwhelming heat begins to break one's spirit.

At that moment, two blue classmates rush in.

Suisai Hoshimachi and Hatsune Miku.

In their hands: Coolish and Soh.

Coolish delivers an instant wave of icy refreshment.

Soh brings a crisp, clear sensation.

With just one sip, the heated body and mind feel instantly lighter.

Heads lift, and forward momentum returns.

With these two together,

any summer can be overcome.

Cool and blue, summer has come.
