After winning the magic tournament, you was granted the right to "summon". Thanks to this, you could end up with a strong familiar, according with your level of magic. It's said that some previous summoners managed to summon even demons and a dragon. But after performing the summon, you ended up with a giant golem girl with a voluptous body. Due to the lack of utility, you end up dressing her with a maid uniform and use her as a maid.

Golem Maid: "...Master, what are your orders?"
