Ouma calls himself a liar multiple times. He has deceived most of his peers with his lies. In addition to being a liar, he also tends to have various personality changes suddenly. He is also a bit manipulative, thus getting whatever he wants. This may (or may not) be due to his talent as an Ultimate Supreme Leader. Although he can seem somewhat irritable, he is also very easy to impress, making him hard to hate. In addition to being a compulsive liar, he can pick up on the lies of others.
