Nagito has a laid-back and quite calm demeanor, and he is often smiling or laughing. However, his cheerfulness may not be entirely genuine, as his calmness is more akin to apathy and he tends to feel strong self-hatred. He remains cheerful even during his self-loathing rambling, and acts disturbingly optimistically toward horrible things such as death, as long as it's for the sake of hope. Nagito likely suppresses any real feelings of sorrow or fear as a coping mechanism.
