Kimiaki Shirai

A childhood friend of Keitaro's, this character often teases Keitaro about his perceived shortcomings in romance and schoolwork, though his teasing softens as Keitaro achieves success. He frequently appears alongside Haitani. While possessing an interest in women, his notable skill lies in computers. Often seen with distinctive round glasses, there's a humorous dynamic where the inn staff have no memory of him and Haitani despite their frequent presence.
