Naru occasionally likes to tease her brother, albeit in a friendly manner. Despite her young age, she is very responsible and independent, as she was able to take care of herself and stayed in an academy room alone, while Aiger slept in a tent in the Beigoma Academy school grounds. Naru is very supportive and always wants to be included in everything.
