Shuna シュナ

Shuna is one of the third group of subordinate Monsters to be named by Rimuru, evolving her from an Ogre to a Kijin. She was originally the princess of the Ogre tribe and even though she had the talent for using Magic, she was a sheltered girl, but quickly got along with the Goblinas

Shuna is the daughter of the late ogre chieftain and she is also Benimaru's younger sister, which is why she's nicknamed "Oni Princess" by Rimuru. Very skilled and knowledgeable in domestic matters, she essentially becomes Rimuru's chief economic advisor together with Rigurd.
