Kamiyagi Ruriko♀

Ruriko is a 2nd year student in Final Course. A true lady, she is the sole heir to the international Kamiyagi Corporation. Rumors say that when she goes home during vacations, she can’t go outside without a bodyguard. Perhaps because of that upbringing, she sometimes seems ignorant about the wider world. Many of the girls at Vincennes are considered ”hothouse flowers,” but even among them, Ruriko appears shockingly sheltered.

Her good breeding makes her popular at school. Her title means ”Bijou Bleu” (Blue Gem). She helps anyone she meets indiscriminately, and even befriends Chiho despite her outcast status. She’s always with her pet, Panterbell.

”Masaya-san, you were my first...”
(Translation: ”You’re the first boy I ever shook hands with”)
