shitty yj fan character go!
Seras, the Putto Lad, is the foil to Klarion, the Witch Boy. :u There. I said it.
He is a Messenger of Hope & Harmony. His role as a Messenger is to tire out the opposing side, so that Life can keep living before Order and Chaos put each other out and the Universe falls into stagnation.
Messengers don't use their powers to force Order/Chaos. They let living things find the right path (Whether good or bad), and help along the way. They [should] have no interest in killing a Lord, only to make sure they won't wreak Peace/Havoc for a day.
When Seras isn't spreading a little good, he's watching out for Klarion to make sure the witch-boy isn't up to no good.
He has shoulder-length, white hair, wears wraps/some-toga-like-thing (But has an opposite coloured outfit to Klarion's I told you HE'S A PURE FOIL), and his familiar is a (baby?) Pudu deer, named Ozree, that he keeps in a satchel.
...okay that's it. I just wanted to write that down.
