Ryōko Toba

In the original story, he appears in Chapter 11 along with his sister, Minami. When they meet at the campsite, he helps Rin, who is struggling to light the binchotan charcoal, and is called the "Fire Master" by Nadeshiko. With an androgynous appearance, he is mistaken by Rin and Nadeshiko as Minami's "boyfriend" until his gender is revealed in Chapter 23. At his sister's request, he provides equipment and his Nissan Lafesta-style minivan for the Outclub's Izu camping trip, and he regularly contacts his sister out of concern during the camp.
