Waifuu Summoner

Ren is an orphan and working student that summons to another world. He gained a class called summoner but there's a condition to unlock the class. That is... To find a density of mana with many dangerous monsters lurking around. What the heck? Isn't this asking me to die? When he entered the dungeon of Abyss He was forcefully dragged into a teleportation trap. Then he teleports all the way to the 100 floors of the Abyss And met a giant black bear. While he is being chased by the giant black bear. [You met the condition!] [Waifu Summoner is unlocked!] And that's how Ren, life changed. ==================================== This is just a Fanfic! Also, feel free to criticize!
