Kaburagi Yukie

Known to Ren and Ichika as the "Kind Older Sister" who lives next door to the Ougi house.

Although they go to different schools, the three of them sometimes go to school together when time allows it. Yukie also loves Ren and Ichika as if they were her younger siblings.

In particular, she shows a playful side to Ren, and likes to tease him sometimes. She is the student council president of Shiraba Academy, and is well respected by the students for her accurate and reliable execution of all tasks.

"Hehe. You've changed a lot, haven't you, Ren-kun? ...You've gotten a lot cooler."
