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