Akira Yagami was a normal office worker in his past life. When he gets run over while trying to save a child, he gets reincarnated as a goblin.

Goblins only have a lifespan of seven days, but Akira has the skill "Human 80 Years" which gives him the lifespan of a human while also gaining the power of a goblin. Goblins are able to inherit someone's skill when they die. Akira collects hundreds of skills from his fellow goblins and wields them when needed.
