Episode 51
Ogi Zenin's technique wraps a katana blade in intense flames, turning an ordinary sword strike into an incinerating slash. The fire burns hot enough to cause severe burns to sorcerers, and the combination of cutting edge plus fire damage makes each hit especially punishing. The technique suits Ogi's fighting style, he's a trained swordsman who relies on clean, decisive cuts rather than flashy cursed energy attacks.
