Kanteishi wa Douga Haishin de Level Up Suru

In a world where your ability to take on dungeons reflects in your status, Akisora Shuu was given the class “Appraiser”. It’s a never seen before class that’s not suited for fighting, so nobody cares about his ability. Thus, he lives a repetitive and mundane life. Then one day, after he posted a video sharing the information of a monster he had appraised in the dungeon, he suddenly leveled up. It turns out that it was because he received a share of the experience of his viewers whenever they defeated the monster he had video’d about. Now, with a way to infinitely level up, he charges into the dungeon to save the person most important to him!
