Mitsuhide Lowen

One of Zen's closest aides was appointed by Prince Izana to watch over Zen (despite initially wanting to be Izana's retainer), and though their relationship was initially rocky, he is seen by Zen as both a close friend and reliable aide.

He is extremely loyal though somewhat clumsy at times, as well as a little silly. He doesn't often say what he thinks. It is hinted he has feelings for Kiki.
