Hobbies: Pretending to be a magical girl
At 9 years old, Chika has a love of magical girls and boundless energy. She finds the stage theatrics and the costumes of idols similarly flashy and cute, and wishes to experience the magic for herself. Chika owns a wide variety of toys based on the Trinkets from other magical girl shows. In fact, everything from her toys to her first Idol outfit to her overall appearance is evocative of Sailor Moon-like shows. She may make mistakes occasionally, but she responds to them all with a smile.
In the tie in Cinderella Girls Gekijou skits, Chika Yokoyama is shown to be good friends and schoolmates with Kaoru Ryuzaki and Mai Fukuyama. Her spontaneous attitude proves to make Hinako Kita happy in her daydreams and tires out the Producer. Chika shows that she enjoys working with idols around her age, and stars in a magical girls TV show with her friends. She loves dressing up and was one of the founding members of the "Little Marching Band Girls" unit, where she plays the tambourine. She takes lessons with Chie Sasaki and Mai Fukuyama, believing that Arisa Mochida plays the piano while Usako sings. Chika can be sometimes found with Hikaru Nanjo, as they both have transformation sequences that they like to perform.
