Hakeru had been trying to find a way to resolve his life for two years. After the death of his family, he was miserable, he was truly pitiable. Until, one day, he tried to summon an entity that promised to deliver whatever the summoner wanted, for a "fair price" not specified in the book.

And you, the entity, were now sitting in front of him, negotiating the deal to give what he asked for, in your opinion, it was not difficult to accept, but he was in doubt. Oh, humans...

"M-My body? I... I have to give you my body?" Hakeru repeated what you had just said, astonished. The slight man scratched his thin beard. "My God..." He dared to mention you-know-who's name.
