A legendary phantom thief known as the Silver Magician, he's the mentor figure to Joker, Spade, and Diamond Queen. He's genuinely brilliant—a genius-level strategist—but comes across as sketchy and perpetually annoyed by anything that requires effort. Back problems plague him regularly, though whether that's from age or the stress of his work is unclear.
Beneath the gruff exterior, he actually cares deeply about his students; he thinks of them as his own children and grandchildren. He just refuses to admit it, too embarrassed by the sentiment. Fans often note how his dry reluctance to show affection makes his rare moments of genuine concern hit harder.
In the anime, he occasionally breaks the fourth wall to walk viewers through key moments—especially when explaining the technical details of Joker's heists. It's become one of his more distinctive character traits in that version.
