On the official site for the video game for smartphones from the franchise High School DxD special event entitled “Enter! Mischievous Demon Girls!“, Available within the application from December 11. The video game is only available in the Japanese market and in a catalog QooApp in this link. The event is described as follows:
«The number of new customers is increasing, perhaps because they miss the Christmas atmosphere. While we are pleased that the number of applications is increasing, there are times when we are rejected because people do not believe we are demons. Leave it to me, I have an idea! “I think these outfits will make people realize that we are demons.” That's it! Let's get the devil out of our suits! “I understand you want to point out your misconception, but what do you want with all this exposed skin?” Of course, that's what I want to see… Hmm! Of course, it's about improving contract rates… We're about to get new contracts!».
High School DxD Summary
High school student Issei Hyoudou is a regular who does nothing productive with his life, spying on women and dreaming of having his own harem one day. Issei seems to be searching for things when a beautiful girl asks him out on a date, even though he's a fallen angel who brutally kills him. He gets a second chance at life, however, when the beautiful senior Rias Gremory, who is a world – class demon, revives him as his servant, recruiting Issei into the ranks of the school's Occult Research Club. Slowly adapting to his new life, Issei must train and fight to survive in the violent world of angels and demons. Each new adventure transcends many fun (and racy) moments with your new classmates, keeping your new life a secret from your friends and family at DxD High School.
