Toki is the head, and currently only, healer in Fukutsu no Seishin.
He can be somewhat short-tempered at times, particularly when yet another young and naive dragon ventures into the coliseum without the appropriate supervisors and comes back limping, unable to fly.
The only perhaps unusual thing about him is the glowing rune above his forehead, although that is common within the clan. What is less common is the young age at which he obtained it, compared with most.
As the sole clan healer, Toki is forced to be available all the time for medical emergencies, although those are rare. As such, he is a bit of an insomniac, but very good at what he does.
