Maruno Satou

Maruno is a young short girl with shoulder-length dark-green hair that is tied side pigtail on the left side and dark-green eyes. At the Kanto Bouldering Championship, when Sayo Yotsuba and Chinari Iwamine bump, Maruno joins the conversation and states she had seen all of the exploits of Sayo's team, but as their team is participating their "exploits" will be "patched". Chinari congratulate Maruno on her words, which makes Maruno happy. She manages to pass the prelims, but in the semifinals she feels pressured by Konomi Kasahara success, thinking that the routes are easy, but fails to pass the semifinals.
