Bellflower is Sae Ha's absurdly laid back cow.  Usually he can be found roaming the Kyung-Sang region with Sae Ha casually riding him as he meanders around.  Currently he is residing at Yu-Jin's place with Sae Ha and the rest of the Tals that have gathered around the new king.

Bellflower doesn't seem to get worked up over much--including being lifted into the air by Shadow.  The afore mentioned incident happened when Mu-Young briefly took the bovine hostage in order to get Sae Ha to visit and take care of Yu Jin's eyes.  Bellflower appears to have the ability to understand and communicate with the Ju-Ze but he is, as far as has been revealed, just a normal cow.
