Jin is an active and friendly creature, as opossed to Yin. He can usually be seen around bamboo forests, protecting them from intruders with evil intentions and helping any creature in need. He respects all forms of life;
He may seem small, but he's brave and witty. He also carries good fortune, so it's not wise to be on his enemie's side!
Yin is shy and a complete introvert, as opposed to Jin. He prefers to hide in the shadows, where he can't be seen, and watch without being watched. Agile and intelligent, cunning and stealthy, he will always avoid fighting if he has the chance.
He will faithfully serve those few he considers worthy of his help, the intelligent and capable.
