Class ga Isekai Shoukan sareta Naka Ore dake Nokotta n desu ga

Summary

A god of a different world had abruptly appeared in Kamiya Yato's classroom and forcibly summoned the entire class to his world... except for him-because he was sleeping in a seat in the corner of the class, and the summoning magic circle didn't reach him-and he ended up staying here on Earth, but with brand-new skills. After he made it through a whole year full of police interviews and journalism reports, he finally became a high school student, but the quiet days he had hoped for were far from over-be it terrorists who decide to occupy his school or even monsters from different world, one by one new incidents take place in the town he lives in... Will a boy without any motivation be able to save the world? (Source: Novel Updates, edited)
