- Description from novelbuddy

Reborn as a sword, he lived for hundreds of years, and then he occupied the body of a 15-year-old prince.

I opened my eyes to find myself in another world. For some odd reason, I ended up as a sword. Before my eyes laid a plain full of magic beasts, and so, I launched my body and flew in search of a partner, a wielder (females only). Wait. Absorbing magic stones gets me skills? Oh hell yeah! This be fun! More, more, give me more! Gimme all your magic stones! Okay, yeah no, but I am accepting anything anyone’s willing to give. This tale is one that follows your everyday nerd, normal as could be, save for the fact that he happened to reincarnate as a sword.
