A Magic Knife, Chop Down the Goblin!

Traveling through the Fairy Tail world, you get the King of Slash system and unlock the Shadow Assassin template at the beginning. Kenpachi, Hawkeye, Xubai... When one template after another merged, a swordsman who wielded a sword to fight was born in the magic world. "Why, he can chop my flames." Fire Dragon Natsu looked shocked. "The strongest magician, he is the only one worthy of this title!" Gildarts looked solemn. This novel and its characters are purely fictitious.
