Dantoudai no Hanayome – Sekai wo Horobosu Futsutsuka na Tatsuki desu ga

A “dragon” appears from a container that fell in front of Dazai Ryunosuke’s eyes. The disastrously beautiful “dragon,” Rinne Irako, had been condemned to death as a world-destroying calamity, and was being transported to a place of refuge. Rinne Irako was sentenced to death and transported. But as fate would have it, the “dragon” girl had a miraculous encounter with a boy, and her destiny was about to change drastically.
