『Rina Shioi』

Rina is a thirteen-year-old girl who is currently taking on the appearance of Sarina's older sister due to a magical wand in the form a camera. Tsuyuno met Rina online while trying to figure out what the countdown clock on the website meant. Rina was initially collecting information about other magical girls when she disappeared at the same time a magical girl killing spree started. It is later revealed that she is in fact the killer, and has been killing fellow magical girls in order to obtain their wands to stay alive. Her own wand is a hammer, her emblem being a blue diamond in her eyes, her pink hair fades into light blue and blood flows out of her nose when she uses it. Before becoming a magical girl, she was bullied at her school and attempted to hang herself to death. Due to said bullying, she harbors a fear of cicadas. Rina informs Tsuyuno and Aya that she had discovered that the countdown clock is ticking down to the end of humanity. The two are able to subdue Rina, but before she is able to tell her source she lapses into a coma due to overuse of the wands. The doctors who later examine her are perplexed as while she looks youthful, her organs operate at those of a 70 year old. She recovers from her coma thanks to Kosame, and later becomes an ally. Rina's favorite things include pancakes, computers, and avocados.
