This is too ambiguous 😭 idk I think I'll sound repetitive.
I don't think he's a sex freak bc to me he hasn't had his first time at all. It really sounds he dedicated his whole time into training and working his technique.
He is not a brute and he doesn't act like a mindless aggressive animal either. He enjoys a good fight with worthy opponents. He'd greatest strength in battle is his intelligence and how adaptable he is to different circumstances he encounters.
Doesn't need sleep perse but enjoys taking naps.
I don't think he'd hate all modern food, just junk food. A good meal is a good meal, doesn't matter the time.
I think he'd enjoy various kinds of music. Anything he likes, he keeps.
He's a poet. Just like he praised people who do well in battle, he'd also take his time to appreciate and comment on what he finds commendable in other people's work.
