Imagine somewhere in the wide expanse of the multiverse, there exists a human version of Rias Gremory? A bumbling Plain Jane otaku who's considered a general nuisance by the students of Kuoh Academy for her blithering antics. One night, after being targeted by a nefarious fallen angel who pretended to be her friend, she is rescued by her crush, Issei Hyodo, the school's idol who is also a powerful dragon deity from ancient lore. She eventually finds out that she possesses a magic red gauntlet housing the spirit of a powerful Welsh dragon. Issei then takes the flat-chested nerdy girl as his apprentice and vassal so she can master her powers so she can fulfill her dream of becoming the Otaku Queen. 

#1 Rias discovering she has Canon-Issei's swag
#2 "Woe is me, Y HAVE I NO BEWBS?"
#3 How does it feel to be on the receiving end of teasing, Rias?
#4 Obligatory fujoshi nosebleed (she just saw Issei's Johnson)
#5 *insert your own dialogue here*

Probably a concept I'll make into a fanfic one day...
