Chika is the oldest member of the Fukuhara family and is the oldest in class 2-B. She is the ultimate technician and a famous hacker under the name of her alter ego 'Dispeariss'. Chika is mature, calm, and very manipulative. She even calls herself the ultimate hero after its revealed she is the mastermind. The thing with Chika is that she believes she is being the "hero" by trapping her classmates in a killing game (we are heading into spoilery terriritory so ima stop here). She has always loved computers, her father and her bonded over their love for screens, once her father went bankrumpt, she promised him she would make millions for the family, and would go to the library to practice programming. By the age of 9 she created 5 robots and 1 super computer. Once she learned about Star Shine academy she made it her goal to attend there. She managed to hack into the system and sent herself an invite to the school. She acts motherly around her classmates and deeply cares for them.

I imagnie her voice being fairly deep but not too deep.
