Kokoro Tsurumaki

Height: 155 cm (5'1")

A happy-go-lucky student at Hanasakigawa Girls' High School and the leader and vocalist of Hello, Happy World!. Her family is ridiculously rich and lives in one of the biggest houses in the area. She's the only member of her school's astronomy club.

Kokoro is an idealistic and charismatic young girl whose goal in life is to make the entire world smile. She effortlessly attracts others to her with her bright and bubbly nature, often sweeping them up into her easygoing pace. She is easily able to do and get what she wants, no matter how absurd the request, mostly thanks to "the suits": three bodyguards that follow Kokoro around that can seemingly accomplish anything she wants like magic, appearing out of nowhere when they're needed. As a sheltered rich girl, Kokoro is ignorant about certain normalities like taking the train.
