Narumi Momoyama is major supporting character in the Murciélago series. She's one of Kuroko Koumori's main love interests and former member of the cult The Virginal Rose. She also has crush on Chiyo Yanaoka and respects her deeply. Narumi is very hotheaded and doesn't particularly care for social norms such as politeness, as seen when Goldmarie repeatedly calls her out for using curse words. However, she also has the tendency to be shy and awkward at times, especially when she's flustered.
