Yandere Girls? I Think the Black Hole Trigger Is Better!

"Zheli, what can I do to make Shouko willing to come back to Crychic?" Just tone it down a little. Next. "Trainer! There's a superstition going around the racetrack that a trainer can't win again after marrying their horse girl..." To disprove it, I've decided not to get married. Next. "Mr. Zheli, I'd like to invite you to the Hanamizaka festival with me..." Go discuss it with the two above. Next. "Madoka... Madoka..." That damn Walpurgisnacht is still chasing me! ...Having gained the template of a snake-like monster, Hotta Zheli just wants to quietly run a cafe. But one obsessive woman after another keeps showing up at his door. At this point, there's only one thing to do: blow it up with them! "OVER THE EVOLUTION!" A mere obsessive woman is no match for a real black hole! What kind of gravity-field love-triangle hell is this? Today, I'll blast it all to smithereens!!! - A multi-world travel story, slice-of-life style, similar to Shinya's Diner. The first world is MyGO, the second is Genshin Impact. The title and blurb are terrible, so please go read the story!
