Hellhound.

A quick death would be mercy for those villains. I will never grant them such a wish. I want them to live in fear knowing that Nightmares are always lurking, behind every corner, behind every shadow, I will be there.

-- Hellhound

Not much is known about him, apart from his real name, Mako. An infamous anti-hero, he is driven by the desire to eliminate all evil and break free from his curse. Beneath his tough exterior lies a kind heart, deeply scarred by the injustices of the world. Mako holds the belief that death is a form of mercy, and therefore refuses to kill criminals. Instead, he subjects them to torment as punishment for their wrongdoings. Despite his dark methods, he shows an unexpected tenderness and ease when interacting with children.

Backstory

As an orphan, he never knew his parents, relying instead on his closest friends from a rundown, corrupted city. Though often treated like gum under others' shoes, their bond remained unbreakable. Together, they weathered the worst and cherished the best moments. However, fate had a cruel twist in store. The corrupted god, Venderflik, descended from the sky to erase the city's slums from existence. He bravely fought to defend his friends, but Venderflik overpowered him, tearing off his arm. When he woke from the trance, he discovered his friends had been killed, his arm replaced with a wooden prosthetic, and he was left with a mysterious curse-slash-power. With this new reality, he embarked on a mission: to heal himself, uncover the truth about his friends' murder, and take vengeance on Venderflik.
