Summoned in another world... as a summon being???

A Filipino college student was summoned to another world, but only as a summoned being from a female summoner within it. * Notes: It's a classic Isekai series only. So expect the classic goblin quest for the MC'S first quest as adventurers. Obviously, the main characters are adventurers. And most of all, do research on the Reward system of the series Mato Seihei no Sl@ve Chained Soldier manga
