Welf Crozzo

Welf Crozzo is a skilled blacksmith and adventurer in Is It Wrong to Try to Pick Up Girls in a Dungeon? (DanMachi). He starts as a member of the Hephaestus Familia but later joins the Hestia Familia, becoming Bell Cranel's personal (and eventually the Familia's main) smith.

He's a descendant of the fallen noble Crozzo family, known for their ability to forge powerful magic swords, though Welf initially refuses to make them due to disdain for people who seek such weapons just for fame or power. He has a straightforward, honest, and casual personality, often acting like a reliable big brother figure to Bell and his friends. Physically, he's depicted as a tall young man with short spiky red hair, dark blue eyes, and typically wears a blue scarf with practical adventurer attire.

Welf is also an adventurer himself (frontliner/fighter type), with abilities including the unique skill to create magic swords and a spell called Will-o-Wisp that's particularly effective against mages.
