“The boxing champion in Belobog's Underworld, and one of Wildfire's most capable fighters.

The consecutive champion of the Fight Club inspires the dreams of children in the Underworld with his enthusiasm.”

Luka was one of the characters that have been long rumored to be playable, and we finally have information on his kit!

He is a 4-star Physical character following the Path of Nihility. Despite his Nihility alignment, he has a lot of DMG output on top of the Bleed that comes from his abilities.

He's voiced by Howard Wang in the English voiceover. Wang also played the roles of Whitley Schnee (RWBY), Louis James Moriarty (Moriarty the Patriot), and Shu Ogata (Engage Kiss) in the past.

Luka's Japanese VA is Gakuto Kajiwara, sharing him with Asta from the Black Clover series, Shinra Kusakabe from Fire Force, and the Protagonist from Monark.
