Nomura is brash, oblivious to subtext, and can be careless. He is generally cheerful, but at the same time hotheaded, as it is easy to confuse or provoke him into indignation. He is quick to make excuses and blame others in minor situations, such as the several occasions he gets in trouble for talking back, but he is still able to take responsibility for his more serious decisions. His loyalty to the Shinsengumi is such that he is capable of great self-sacrifice for a greater cause.
