Rivale

Rivale (リヴァーレ), also known as the Bloody God of War (られし), is a Great Demon. He is recruited by Solitär to fight the Hero Party when the Demon King senses that Frieren has interfered with space-time. Rivale fights Eisen, and out of respect for Eisen's strength, chooses to face Eisen with an axe. He survives the encounter and later attacks Stark's village.
