People are in Zongman, Starting with Gabriel

Dong Huangxuan traveled to another world, thinking it was just an ordinary one, where he could just live a peaceful life. But who would have thought that next door lived a little girl named Izumi Sagiri who loved drawing. And the girl next door who was entrusted to live in his house was named Kafu Chino. Did Yukinoshita Yukino and Shinomiya Kaguya quarrel over whether to join the student council or the service club? Did he meet his in-game teammate offline, a blonde girl named Gabriel? Did his deskmate who often takes leave turn out to be a celebrity named Sakurajima Mai, who also has some super powers? And why did a giant dragon suddenly appear here, just like a dragon that was stabbed by a sword? Hey, hey, hey, where is the peaceful life in the ordinary world?!
