Book of unreturned

Anime

"He didn't even finish any items!"

And its like a loki type calm character where gods and angels were descending and he

only finished what he needed in all sections, a jack of all trades of sorts where some people crafted swords, some worked on their chi, this guy... however... worked on just moving forward. And so when he descended he had no weap0ns or armor to fight the gods and somehow before he died with no story, a book was written of him that triumph over all the over "Gods."
