Kaerenu Oni to no Momobiyori

"I'll pour my magical power into you..." Otaku salaryman Momose, who loves fantasy and parallel worlds, comes upon a book that he used to read a lot in the past: The Complete Collection of Summoning Magic. Feeling nostalgic, his middle-schooler heart reignites, so he decides to try and chant once again the summoning spell to call the "Servant of Fate"... But suddenly, in doing so, a demon named Keiha comes out of his closet?! A slightly naughty BL daily-life story about a demon tied by an invisible force x a salaryman!!
