I Reincarnated as a Mob in a Magical Girl Anime, and After Repeatedly Saving Them from Near-Destruction as a Mysterious Entity, They All Turned Yandere

I just wanted to see them suffer a little… but somehow, they turned into yanderes… I, who love to see magical girls in despair, reincarnated into the world of my favorite magical girl anime as a mob character named Sota Hayami. One day, after watching the magical girls fight as usual, I was touring a holy site known for corruption when, for some reason, I awakened a demon god that had been sleeping there. For some reason, the demon god seemed to take a liking to me. I merged with the demon god, gained overwhelming power, and took on the mysterious persona of Omega. I kept watching the girls from up close, enjoying their dire situations, and then saving them at the last moment. Before I knew it, they had all turned into yanderes.
