Rinka Himeji

A former middle school junior to Adachi, this eccentric transfer student carries deep emotional scars from being disowned by her adoptive family. After a brief period of homelessness, she found refuge in Adachi's home, though she initially struggled while staying with Shinagawa. While she boasts a quirky, unpredictable mindset and an intense competitive spirit, she possesses a hidden, domestic side. Despite her occasional temper flares, her outbursts are often perceived as adorable by those around her.
