No One Knows More About Romance Than I Do!

To improve her matchmaking skills, discard outdated ideas, and boost the GDP of true love among mortals, a certain matchmaker from the East (x)... the God of Marriage began studying all kinds of dating games, thanks to recommendations from her attendant San-chan, a spirit born from the Tree of Three Lives. After a bewildering series of operations, every character got a bad or terrible ending in her first, second, third, fourth, and fifth playthroughs. Then one day, she went down to the human world to shop, filled out a survey, and ended up transmigrating. Only afterward did she learn that the System hiding in the game couldn't stand to watch any longer, so it had brought her on a romantic journey (training program) with no strings attached. Goal: Get a happy ending for everyone. Games include, but are not limited to: "The Rumored Girlfriend of Yokohama's Twin Underworlds" "Life with My Yandere Junior at Home" "The Little Love Genius Takes on Demon Slayer Academy" "The Cat-Eared CEO Who Loves Chess Is Super Cute" "How Lonely and Empty It Is to Be Invincible" God of Marriage: Hah, are you telling me what to do? (Blocks the System) And so, one day, a street performer appeared in usually peaceful Yokohama, trying to make a living. God of Marriage: Come one, come all! A divine performance is a rare opportunity. Requests welcome. When the System finally unblocks her: What are you doing?! (Screams) God of Marriage: Obviously, I'm spectacularly slacking off. (Finger heart) Reader's guide: #Multiverse crossover, including Bungo Stray Dogs, Fate, Demon Slayer (modern version), Arknights, Jujutsu Kaisen, and more. #Anything that differs from the original can be treated as my own headcanon (I sometimes accidentally remember details wrong). OOC warning. #First-person narration. The female lead may seem a little... unlikable at first, so beware. #The pairing is undecided. Place your bets. #More to be added as I think of it. Thesis: Travel the world and see all the true feelings of humanity.
