Rumi's twin younger sister, Ruka, is more reserved compared to her sister. Despite this shyness, she occasionally exhibits emotional outbursts similar to Rumi. During an exploration of an ancient burial mound, Ruka contracted a virus that granted her supernatural abilities, such as flying and the power to pass through objects. Interestingly, she also developed an antibody against the virus spread by Rumi. This twist of fate brings Ruka into a complex love triangle with Touma Katsuyuki, stirring deep internal conflict within her. Torn between her affection for Katsuyuki and her bond with Rumi, Ruka finds herself at odds with her sister over their shared interest in him. Nevertheless, amidst this turmoil, Ruka harbors a hope for reconciliation with Rumi, longing for a resolution that could mend their fractured relationship.
