"Activate ability: Fire Control"
Yuki used his ability to engulf his blade in his crimson flames. However, due to him being mentally unstable, the flames extended out of the blade upwards, as if creating a larger sword in combination with "Fallen angel of hell".
Yuki leaped off the ground to strike down Hades with his enormous flame sword. However, Hades wasn't going to back down without a fight.
