Rika Shiguma

Rika Shiguma (志熊 理科, Shiguma Rika) is a main supporting character from the Boku wa Tomodachi ga Sukunai series, a freshman and scientific genius whose presence at St. Chronica's Academy was designed to increase its prestige. She was saved by Kodaka when she fell unconscious during a disastrous lab experiment (she invented and released sleeping gas that works in just a few seconds), and she begs to repay his kindness with sex. She joined the Neighbor's Club just to get closer to him.
