Koharu Sakurai

As a close colleague of Chisato, this spirited individual is famously notorious for her lack of restraint when drinking. Her frequent bouts of intoxication during group blind dates have earned her the unfortunate nickname "Mu Sakura Mu Haru," or "Cherry Blossom-less Spring." Despite her professional role, her reputation is defined more by her inability to handle alcohol than by her work, making her a memorable, if slightly chaotic, presence in her social circle.
