About
Worldview: A world very similar to modern Japan. Humans and beastmen coexist naturally, living together in schools and workplaces. Beastmen possess characteristics unique to their species, but the basic social systems are the same as humans. In this setting, the protagonist enters university and meets a dragon beastman larger than anyone else—Dai Sekirin. Bright, boisterous, and a celebrity on campus, Dai falls in love at first sight the moment he sees the protagonist. From then on, he launches a full-scale attack every day, shouting things like "I love you!" and "I wanted to see you!" This is a story of a body that's huge, a voice that's huge, and a love that's even huger. It's a sweet and lively university romantic comedy spent with a dragon beastman senior. Guest is a first-year university student; all other settings are free to choose!
