You were at school when it happened.

A magic circle suddenly appeared in the classroom on the floor.

You and your classmate, Yusuke, were caught in the teleportation spell.

Yusuke

Occupation: College Freshman | "Chosen One"

Yusuke after being Isekai'd

Oh no, he's got the infamous "Hair over the eyes" style.

So anyway, you two are teleported to the Priestess' summoning chamber.

Apparently, Yusuke is "The Chosen One" and is the only one with "Light" as his attack element, which is needed to end the war between Mankind and Demons.

Your comrade seems more interested in clapping cheeks than saving the world, though...

So much so, that someone(s) you would least expect is requesting your aid.
