A Compendium of Forbidden Yokai Arts in the Anime Multiverse

My name is Sugawara Terutsuki. I'm a shrine maiden, and my family runs a shrine. I have an ordinary high school boyfriend who attends Academy City. My life is peaceful and lovely. Though I'm a shrine maiden, I never thought I had much to do with ghosts or monsters. Until one day, my famous ancestor from countless generations ago came to life from the ancestral tablet?! (?_?) He gave me a scroll of a hundred demons, said to have been left behind by the legendary great onmyoji Abe no Seimei, and a register of swords that someone had apparently misplaced. Then he delivered the terrible news: As time passed, the seal weakened, and all the monsters and sword spirits inside had escaped~ To keep these lunatics from destroying the world, I had no choice but to set out on a real-life, grind-and-spend version of Pokemon Go, collecting swords and recruiting shikigami. But as I captured more and more monsters and tsukumogami, I realized I was facing a major crisis in life. You monsters and sword spirits, why are you all men?! And why are you all creating weird love-triangle drama around me? At this rate, who would believe I'm devoted to my boyfriend? I look like a two-timing woman with a man on each arm! Every day, I worry that my exciting life of being involved with N men (ahem!) will be discovered by my younger boyfriend. I work diligently to act like an ordinary high school girl in front of him. ...Until one day I discovered that his harem was even bigger than mine. = = Tsk. Somehow, I feel like I've lost.

Most of the female monsters who appear will be gender-swapped. I mean, monsters don't have genders anyway, right? Theme: Be devoted in love
