Forced into a Blind Date by a Bad Woman [Crossover]

*I'll start this once the Chainsaw Man school arc is out! Opera is an ordinary devil hunter under the Public Safety Bureau. She works tirelessly on the front lines of devil hunting every day, hoping to earn the favor of her beautiful boss. One day, her beautiful boss, Makima, called her over kindly: "Opera, I'd like to introduce you to a boyfriend." "He's six years older than you, teaches at a school in Tokyo, has an outgoing personality, and is very handsome." "Opera, you'd like that type, wouldn't you?" "So seize this chance and make him fall for you." After yet another arranged date set up by her boss, Opera fell silent for a moment, then asked politely: "What should I do about the black *ss boyfriend you introduced me to last month?" Makima gently curved her spiral-patterned eyes into a smile. She said, "I'm still the most important person in Opera's heart, aren't I?" "A boyfriend who's no longer useful can just be thrown away, like all the others." ** That was how it was supposed to go. But the ex-boyfriends she'd thrown away clung to Opera's life like chewing gum. "Opera, for our sake, kill the 'devil' Makima." ** Only after removing the person you consider the most important will this so-called fair competition truly begin. Blurb dated April 25, 2021 **A few things to know** 1. Don't let the blurb scare you. The heroine is playing on a whole different level. 2. A reverse harem romance with a bit of angst and rivalry, including Makima x all heroines. There's some girl-love energy, but it's not strong. Pairing undecided, one-on-one. 3. Doesn't follow the original plot. Main crossovers: Chainsaw Man + Jujutsu Kaisen + Bungo Stray Dogs + K + Detective Conan + Durarara!! 4. No trolling or irrelevant comments, please. I'll be sad and delete them if I see any. 5. Cover in progress. Theme: The past cannot be recalled.
