Tachibana Hinata and Jinguji Tsukasa are two young men who have been friends since childhood. After a disaster of a singles mixer, they’re sent flying into another world by a mysterious being–and now Tachibana is a beautiful blonde girl! When Jinguji angrily demands that they be returned home and go back to normal, they get cursed, and the only way out is for them to go on a quest and defeat the demon king. But…now the two friends can’t stop thinking about how hot the other is. Will they save the world before their lifelong bromance becomes a romance?
