After the Shoujo Manga Protagonist Joined the Main Science Plot

[Coming Soon: [Crossover] I’m Claiming the Zenin Clan Head!] On her eighteenth birthday, Nishino Sari, whose father from the Black Organization was trying to kill her, learned two things. The bad news: Hiro, her online friend of six years, was actually a popular character in the Detective Conan manga, and he seemed destined to die young. The good news: she could use her Stand ability to enter the world of the manga. - After getting bad endings in two consecutive playthroughs, Nishino Sari uncovered the whole truth in her third. She tore up the romance script, slipped into the Black Organization’s uniform without a second thought, and became a handsome part-timer who kept bouncing back and forth between the red and black sides. “If I become the distillery’s top KPI performer, the other undercover agents won’t get hurt anymore!” “I’ll protect Hiro!” And so, a romance manga that had never made much of a splash suddenly became a dark-horse hit and caught everyone’s attention. - [Topic: Huge news! Hiro’s official love interest has appeared! There are signs the police academy gang might be making a comeback!] [OP: The police academy gang didn’t die! It was all part of a big plan by the Hiromitsu ship! I hereby declare Nishino Sari my god! Her official manga volume is coming out soon, everyone, let’s go all out!] Nishino Sari: “...!!!” She might have saved too many people from getting killed off! - Hiro had a dream that kept repeating. In it, he had a girlfriend named Nishino Sari. She did everything she could to pull him out of the mire, her whole body radiating a scorching light. It was as if he had fallen in love with an illusory figure who existed only in his dreams. That is, until he met a member of the distillery named Merlot, who was hailed as its strongest rookie. That person looked exactly like the one from his dreams, but had a completely opposite personality... Reader Advisory: Hiro pairing. This is self-indulgent wish fulfillment QAQ. Unrestrained personal preferences, OOC. I can’t even tell whether the plot or the romance gets more focus. A sweet story with lots of sugar and very few knives. Not told through bullet comments, but it does include forum posts. Only the first and third playthroughs, so it’s really short! Lots of canon changes and original settings, so please be aware before reading. [Check out my other upcoming fic: [Crossover] I’m Claiming the Zenin Clan Head!] Before her cursed technique had awakened, Zenin Uto was approached by a character-building System called “Chosen Clan Head.” “Bind yourself to me! I’ll help you become the next head of the Zenin clan!” The Zenin clan had passed its leadership down through the men for generations. As the legitimate daughter who had lived under oppression since childhood, Zenin Uto said, “Might as well bind myself to you. I’ll be the one to smash this rotten ship apart!” The good news: Uto got off to a great start, drawing the Zenin clan’s hereditary, top-grade technique, Ten Shadows Technique, on her very first pull from the System. The bad news: she was Heavenly Restricted. System: “That’s easy! Just pass the System’s assessments, and you can take your cursed technique home!” - So, during the day She was a low-key overachiever who trained in secret and shocked everyone! “What’s going on?! Why has so much equipment in the training room been destroyed this month?!” “This is bad! Clan Head! The training room’s been wrecked again!” “W-wait! What happened to the trees on the back mountain?! Who blasted them all flat?!” At night She was a ninja trainee at a ninja academy, working hard to learn the combat techniques and theory of the ninja world. “Kunai-throwing technique...” Zenin Uto threw a kunai, and with her immense strength behind it, the target was reduced to dust! Teacher and students: “??????” “Chakra training, ” Thanks to her powerful Heavenly Restriction body, Zenin Uto completed the goal with ease. Teacher and students: “?????? Wait, why do you have so much chakra?!” “Next, hand signs, ” Zenin Uto’s hands moved so fast they became a blur! Teacher and students: “????” “C-could it be that you’re a genius?!” - After she transferred into the technical college Masamichi Yaga: “Why don’t you introduce yourself?” Zenin Uto: “I don’t have a cursed technique. I’m weak.” Suguru Geto and Satoru Gojo: “What a coincidence. I’m strong.” Shoko Ieiri: “Neither strong nor weak. I just have Reverse Cursed Technique.” At the sister-school exchange event, Zenin Uto punched her twisted, dark-hearted older brother into the ground. Looking at the crater blasted into the competition arena and Naoya Zenin’s furious, twisted expression, everyone was like: “????????” Huh? You call that weak?! - In the past, Zenin Uto had no choice. But now “I think I’d like to try sitting in the clan head’s seat, too.” Theme: Love can overcome anything!
