Toyoshige Moriwaki

Toyoshige Moriwaki, widely recognized by his alias 'Professor,' shares a close friendship with protagonist Jun Shirasaki. Despite his sharp appearance drawing considerable attention from girls, his easygoing nature and deep immersion in otaku culture mean his romances rarely survive beyond a week. He enthusiastically engages with Jun and Naori over their shared interests, and when Jun finds himself entangled in a romantic dilemma involving twin sisters, Moriwaki steps in as an outside observer to offer candid, incisive advice—making him an essential pillar of support for the main character.
