Ofc, my queen ❤️ the beginning of the story he was 13, and ended being over 4000 years. The thing is, he is a normal human, but his power which is a black guitar that opens gates to different worlds, and because of those different worlds he landed on, he started having their traits, powers, languages (so he became immortal, can live in different situations, he got copy powers and things that makes him almost inhuman, but he is kind)
That was long, damn (note: he can't return back to earth, bcs when he opens the gate, it takes him to random worlds)
His body: pink hair, red eyes, acts emo at the beginning of each world so he can observe them from afar, which means he changes his eyes and hair black with his powers, and sometimes his skin color to imitate the people. (He gets busted a lot tho) Lastly, he gained a black scar near his eye (like the one in Zoro from One piece) when he was 17
Thanks for ur interest 🫂
