Takeru was a man from Earth, a typical Japanese young man enjoying his life, but in a whim, he ended being summoned by a strange elf, who also resulted being a reincarnated person. This elf had the dangerous ability to summon people through some sort of Gacha power, which made it all random, and he had to always spend gold coins to use it as well, making it quite complicated for him… And he was also quite the useless bastard. I never thought that the intimidating Great Demon of Summoning would be such a lazy and useless man, he just sit around and let his summon do it for him. I mean, that's what summoners do but come on, do some flashy magic at least, don't you have a mana core at least?!
