Mitsuomi is a highly skilled and dedicated martial artist. He uses his position and power to suppress other power users in the school. He is feared and viewed as a tyrant by some as a result. He will do whatever is necessary to that end, he frequently fights and kills bulls in his training so his technique will not weaken when the time comes to kill. He also annihilates any group that threatens his control or the order of the school and frequently using dirty tactics to do so. He also seems to still be in love with Maya Natsume, despite their current disagreements.

Mitsuomi can only fight for three minutes due to a condition with his heart, yet very few can actually last for three minutes against him.
