Tensei Shitara Ken Deshita

When he realized it, the protagonist was in another world and had become a sword that was stabbed on an altar in a great plain, crowded with devil beast. The world he was in had a game like system; HP, MP, Strength, Vitality, Agility, Intelligence, Dexterity, Titles and Equipment.
