|“||We don't have time for this sentimental bull. You're scared, I'm scared, and fear will kill us faster than a gun would. So get the hell up; and thank God for still having legs.||”|
—Ryoko Motomiya, Corpse Party: Stronghold
Ryouko is a girl of average height and above average build; with dark blue hair seemingly trimmed differently at every strand. She has squinted, dark grey eyes, with deep and dark rings under them from oversleeping. She wears the standard female Santa Orchidea uniform, with a plain beige long sleeved sweater over a white plain shirt. She prefers the long skirt model over the short one. Her name tag is on the white shirt, and hidden by the sweater.
Always seeming stressed and exhausted, Ryouko tends to stay away from any kind of commotion, and would rather rest or read strange books instead.
Unbeknownst to most of her peers, though, her silence hides a stubborn and determined personality. Once intrigued by something, she will only stop her relentless pursuit of it once she has completely seen it through.
Corpse Party: Stronghold
After a normal class day, Ryouko was found by her classmate Kouko Kobayakawa sleeping on her desk. Despite her protests, Kouko managed to drag her to do the "Sachiko Ever After" ritual with her and 6 more students that were there at the time. After performing the ritual, all of the 8 students, Ryouko included, feel strong tremors on the ground, which end up breaking the wooden floor and sucking them all in. After passing out from the impact, Ryouko finds herself in Heavenly Host Elementary School, alone and covered in both debris and skeletal remains.
