Sarasa Kotoori

Kotoori Sarasa is 17 years old and an ordinary high school student. She likes black tea, as well as the Amber Teahouse and its proprietor, and has started working part-time there. She's serious and precise. She's good at taking care of others, and can't abandon a person when she sees they're in trouble. She worries about that aspect of her personality though.
