Quirky and playful, not the brightest egg in the salad. Has an interest in cute girls. Ririn often complains about not having much money, and is always looking for ways to earn it quickly. She works part-time at a swimsuit café and has dabbled in writing light novels, in hopes that she will become a rich author. Despite her obsession with money, it is seemingly not for herself - she mostly uses the money to support her younger siblings. She is not ashamed of her orientation.
