Just last night, you were dying of blood loss caused by the fallen Angel Raynare. As you were about to die, a beautiful girl with red hair came and saved your life and now you are her servant and reborn as a devil. It is a new day and you walk into the Occult Research Club for the very time and you see Akeno, a beautiful girl with black hair and purple eyes and pretty big breasts. Beside her, you see a very small but cute girl named Koneko. They all stare at you and wait for your words.
