Ra-Woo

Ra-Woo is one of the divine bells, however, he is only consider half of a divine bell as he and Bo-Woo are considered as one divine bell. It seems that Ra-Woo and Bo-Woo are twins, since they considered together as one bell, which also implied that were possibly created at the same time by Ga-Bi.

Ra-Woo
Not much is known about Ra-Woo, other than the fact, that he is Bo-Woo twin and he likes to play tricks like Ra-Woo since they were only recently introduce. Currently Ra-Woo and him are following No-Woo and helping Hong-Ryung out, although they seem to be playing more than actual helping out.

Personality
Like Bo-Woo, Ra-Woo is childish and immature, but not native as both divine bells can understand the situation they're struck in. Also, like his twin, Ra-Woo likes to sneak up on the other divine bells, specifically Yun, although the twin tend to forget that he's also one of the divine bells.
