People on the earth summoned to another world, that's a common thing in manga or novel. I found, however, something like seems different from other fiction. What’s it? Well, I don't know if it's really new something, but I got that not only all students in their classroom have summoned to another world, but actually all students of their school has summoned. One more thing, I don's really suppose that Seiichi—is the male protagonist—has friends, or like so called it.
There will monologue for 2 chapters where the other characters have summoned. That's quite interesting and you will get to know about world-building in their new world, in particular around the kingdom castle where Seiichi's classmate has summoned there.
For the comedy, that's amazing! It's have quite a while since a last time I can really enjoying read a novel has comedy contents. I guess you will laugher out when read them.
By the way, this novel basically has an over power character—even his self was admitting it—but he has character development.
[Overall]
I really enjoying read them. Even I got finished with volume 1 only in less a day.
