Koenma is prince of the Spirit world. His father is King Enma (or King Yanma), who decides whether mortals go to hell or heaven. Koenma is over 700 years old and still looks like a baby. (He’s in diapers! Lol) He is the one that gave Yusuke the ordeal to come back to life. Through Koenma normally is a toddler when he wants to he can transform into a teenager, but he still keeps his pacifier. There is a power in the pacifier that when removed will cause something to happen, nobody knows what, through.

Koenma is a little full of himself. He really thinks he’s cool and at times has a cruel sense of humor, which he usually shows to the ogre, George. He relies a lot on Yusuke and so forth puts him into hopeless situations, which Yusuke always seems to over come.
