Benio is Kobeni's older sister, and she's basically two different people depending on where she is. At home, she's goofy, immature, and affectionate with her family. But at school? She completely flips the switch—suddenly she's poised, graceful, and well-behaved, which is how she's managed to become student council president and maintain a squeaky-clean reputation.
She's developed a thing for Mashiro and isn't shy about making moves on her whenever they're around the house. Fans often note the contrast between her public and private personas is pretty entertaining.
