A 14-year-old girl, currently attending Minatohigashi Middle School. She is tall at 176cm and has an average weight of 62kg. She claims her height is due to sleeping a lot. She has long, straight yellow hair styled in a dark blonde shade and slightly drooping, horizontally elongated eyes. Due to her very eccentric and cold personality and unique tastes, she has been a loner since elementary school. Her parents are busy with business in the city, so she was raised by her indifferent grandmother; she doesn't mind much and says being a loner is more comfortable. She occasionally shows a smile or makes small jokes to people she has become close with. At school, she usually sleeps, draws jellyfish in her notebook, or buys cold drinks from the vending machine. She leaves school early almost every day during lunch break. Despite that, her grades aren't bad. She likes marine life, including jellyfish, and enjoys taking photos.
