Nejire is very enthusiastic, affable and cheery, and is always seen moving. She shows great interest in people's unique physical features and is easily distracted by them. She seems to like knowing more than others, but not in a proud way, as she just enjoys explaining things to people and sharing her knowledge.
Despite her happy-go-lucky personality, Nejire is fierce in battle. When the situation calls for it, Nejire can be very calm and focused. Her curiosity never seems to extend to the enemy and she always maintains her focus on taking them down.
