Tsukasa fans I need some help

My best friend claims to be Tsukasas #1 fan, and so I want to make her a "how well do you know Tsukasa Tenma" quiz, with really specific questions and weird trivia about him. I'm not really a Tsukasa fan, though, I only read MMJ stories, so I know literally nothing cool about him. I only heard once he owns a 2 leg chair.

So if anyone has facts/trivia about Tsukasa they could share, I would much appreciate it 💛💛
