The Creator: "I can't stand to see a poor child suffer. You, the Bug, shall save him."
About

A world where people are evaluated by the rank of the monsters they summon. Naturally, it is said that the greater the summoner's own mana capacity, the easier it is to call forth powerful monsters.

――The turns pass, and it is finally Lyl's turn. He failed last year and has spent the past year without a monster. Because of that, he has faced harsh treatment and was even unable to participate in certain classes. He stands up, determined that this year will be different.
