Reincarnated as a Goblin, I Was Summoned as the School Belle's Familiar

Wu Yang is reborn as an ordinary goblin in a world of goblins. After finally fighting his way through that world and returning to Blue Star, he discovers that Blue Star has become a world where everyone can tame beasts. He becomes a school beauty's contracted beast! "A goblin, that weak little monster, can fight? Don't make me laugh." "This green, ugly thing has D-rank potential. It's got no future!" "A goblin paired with a school beauty? What a weird combination." Everyone looks down on him. Wu Yang says, "Goblins are weak? What does that have to do with me, the Goblin King?" "Come feel the righteous iron fist of the Goblin King!" Bai Zhiyi is the first female Emperor Beast Tamer in the history of the human race! In her previous life, she was a late bloomer. Though she successfully reached the Emperor Realm, she perished in the final battle against the Abyss. Reborn, she inherits part of her former power and gains S-rank mental strength! "In my previous life, I only had C-rank mental strength, so I could contract just one C-rank spirit beast." "Now I have S-rank mental strength. If I can contract an S-rank spirit beast, I can advance even further and crush the Abyss!" "Come forth, S-rank spirit beast!" "...Wait, what do you mean, D-rank spirit beast?" "And what the heck is a goblin?" Bai Zhiyi is at her wit's end. And then... "I can understand a goblin knowing a little swordplay... but what do you mean, 'one sword splits the heavens'?!" "What do you mean, you know a little swordsmanship and magic?" "What do you mean, a mage who can't blow up a mountain with one punch isn't a good goblin?"
