Always seen with her signature hairpin, Morihei is a highly intelligent and serious woman. She is surprisingly direct and unfazed by most things. Her sincerity rarely comes from a malicious intent, and she makes for very pleasant company when you get on her good side. Unfortunately, it is difficult for many to get over her... obsession with insects.

Morihei has a medium female voice (there is a bit of wiggleroom here). She is much more direct with what she thinks than most other people, and is very logical in her words. That being said, whenever the topic of beetles comes up, she often explains beetle facts without caring what others think.
