Chikama Yashiro is a friend of Hino Akira, who met while they were fishing. Like Hino, Chikama makes her own sound effects, the most notably being the "breathing" sound for her space suit. In her introduction, she explains that she has come to Earth to find her brethren. Chikama wears a full body spacesuit. It has childish design elements, such as hearts and star patches.
