When Sonja fell backwards in his chair, Kushu turned towards him, "Have you never heard of a fukushima-onna, Sonja-onii-san," she asked him. Her second mouth didn't take a break from eating.
Kushu walked over to a mini fridge that was next to Core's desk. She opened it and her two pigtails reached into the fridge and grabbed a bag of chips and a soda. Kushu then went and grabbed two more food items with her own hands. The mouth in the back of Kushu's head opened and her hair fed it food.
Kushu~ "My name is Kushu, it's nice to meet you, Sonja-onii-san," Kushu did a little bow towards Sonja. She turned towards Jeffery, "We're half siblings. I have a different okaa-san, than you do."
Kushu~ Kushu noticed Jeffery's tail, "So, onii-chan has a tail," she muttered.
Core~ "Jeffery, onii-chan, or onii-san, means older brother in Japanese. Japanese children will use it to address their own older brother or an older male." Core told Jeffery.
