I Was a Sword When I Reincarnated (LN)

When I noticed it, I was in a different world.
I had become a sword… what, I don’t get it! The place I woke up was a great plain crowded with monsters. I fly in search of a partner (women only) to be equipped with. Magic stone? I get the skills I absorb? This has become fun! Hyahha, give me magic stones! Yes, that was a joke. But I’ll take a magic stone.
This is how I became a sword and went to another world, a story of an ordinary minor character otaku.
