Rina Saijou

Rina Saijou is a high school transfer student from an elite all-girls academy, known for her polished demeanor and privileged upbringing. Surprisingly, her reason for transferring is deeply personal—she hopes to find a boyfriend. Having spent her formative years in an exclusively female environment, Rina has virtually no experience interacting with the opposite sex. As a result, she approaches romantic relationships and intimate knowledge with the same rigorous, academic mindset she applies to her studies, often overanalyzing even the most mundane everyday situations. The striking contrast between her sophisticated, mature appearance and her comically serious approach to romance makes her a uniquely memorable supporting character throughout the series.
