Allen is a wizard in his twenties with distinctive half-black, half-white hair and blood-red eyes. He typically dresses in ragged robes and has a deceptively gentle appearance—though people tend to find him intimidating when he's angry. Despite his reputation, he's genuinely kind-hearted and goes out of his way to help others.
He's best known for refusing the Chairman position at Athena Magic Academy, even though his adoptive father holds the title. Allen's dead set against taking on any kind of formal role, mainly because he hates the bureaucratic baggage that comes with it.
His past explains a lot. Allen used to be an adventurer who joined a party looking for excitement, but things went catastrophically wrong. During a temple expedition, his party members deliberately triggered a seal, then left him to die in front of a monster horde. He survived, tracked them down, and reported their crimes to the Adventurer's Guild, ensuring they got bounties on their heads.
After that ordeal, Allen withdrew into forest life. The locals started calling him the "Demon Lord" out of fear, though the nickname stuck more from his reputation than any actual threat he posed. That's where he was living when he found Charlotte, a seventeen-year-old girl who'd collapsed in the woods. She'd been falsely accused of crimes, publicly humiliated, and exiled from her country through no fault of her own. The parallels to his own betrayal hit hard. Allen decided to take her in and teach her—his words—"all sorts of bad things," basically giving her the tools and knowledge to survive and thrive on her own terms.
Allen has a younger sister named Eruka Crawford. He was adopted by the Crawfords after his biological parents died, and he was sharp enough to graduate from Athena Magic Academy at age twelve and immediately start teaching there.
