And here's another Oni Slayer character. Her name is Asuna Katsumi. She's another main character, also being a Slayer. Asuna is part of the Katsumi Clan of Slayers, one of the several Great Clans. She's fought against demons and evil yokai from an early age. At first, she considers Kamashi a weakling unfit to be a Slayer, but after several battles, she finally accepts Kamashi as a slayer and worthy user of the Sayer Gauntlet, an artifact bestowed upon the strongest of Slayers. Now she, Kamashi, and another Slayer named Musashi Mifune, work together to protect the human world.

Unlike Kamashi, who fights more like a Samurai, Asuna fights more like a ninja, using shinobi-like techniques and weapons such as shurikens, kunai, smoke bombs, among others.
