Yu-Gi-Oh!: A World of Yanderes!

[A formidable card player once said: I want to become the best in the world. Women are such a nuisance!] [But in the Yu-Gi-Oh! card pool, search for the term "woman," and the first card name that appears is "Tearlaments Kitkallos"!] [So we can conclude that women don't slow down your plays. On the contrary, women are powerful, beautiful, and immortal!] Yougo, a hardcore duelist, changed decks too often in pursuit of strength, angering his own Card Spirit and getting brutally stabbed before he transmigrated. That wicked woman made him transmigrate to another world. Her motives must be impure: she's surely planning to capture him and make him a star slave. Fortunately, he awakened the Girlfriend Card System just in time. All he has to do is recall the decks he has used, approach the related female card characters, and stir their memories. Depending on how much their hearts are moved, he can earn the corresponding cards as rewards. What else is there to say? Branded, Tearlaments, Voiceless Voice, Maliss... Come, partners, and help me! He'll show the world of Yu-Gi-Oh! who rules this other world. I've been a duelist for ten years, after all!

"But who could've guessed that all my beloved decks were traitors, pretending to be loyal and honest? Every last one of them was plotting against me."

"Is that why you got locked in a basement after a duel and ended up with a shattered pelvis?"
