On the first day of school, Bai Ye found Nero on the rooftop, being hunted by a transmigrator. Since they were both transmigrators, Bai Ye decided to take in the capricious Roman emperor for a while.
Before long, Bai Ye found a Dorumon. Half a month later, a silver-haired, dragon-horned little girl calling herself Kanna got lost on her way home from school and ended up on the rooftop.
Looking at the one adorable visitor after another from other worlds in his house, Bai Ye fell into deep thought. What was up with the rooftops in this world?
P.S. A crossover anime series, reverse transmigration, and everyday romance.
