[Western Crossover] Tag-Based Superhero Role-Playing Game

[Completed novel: After Crossing into Gotham, I Only Want to Go Home, pairing with Bluebird] System: Hey, want to save the world? Messier: (turns and walks away) See ya. System: You can convert the money you earn in the game into cash~ Messier: (turns back) I'll think about it. Messier has a problem: whenever she lies, she gets physically nauseated. The trouble is, she has been bound to a System that claims it is improving the game world. She has to enter the game, use character tags to build her persona, and use those tags to reinforce it. She must play seven completely different roles in front of the game's superheroes, until each character's development reaches its maximum. Messier tries to introduce herself: I'm--ugh-- The superheroes: ... Worse yet, the System's tag rolls make no sense at all. For example: A Coast City pilot rolls the title tag [Vehicle Killer]: Any vehicle she rides in is guaranteed to be destroyed (so why does the game start on a plane?) A Bludhaven psychologist rolls the skill tag [Sweat Sniffer]: Can tell if someone is lying by the smell of their sweat (Are you okay?) A Gotham laundromat owner rolls the item tag [Washing Machine That Can Clean Anything]: Including, but not limited to, stains and blood (People too~) A gossip reporter at the Daily Planet in Metropolis rolls the aura tag [Pink Bubbles]: A melodramatic Mary Sue plot will happen within a ten-meter radius (handy for writing articles, hahaha) A fisherman in Amnesty Bay rolls the achievement tag [Even Aquaman Takes the Bait]: Successfully catches Aquaman (the real one) A small-museum curator in Boston rolls the trait tag [Delicate and Frail]: Gazes at the dusty little museum with a sigh (can't manage the cleaning) A Central City police officer rolls the attribute tag [Background Character]: Hellooo? Anyone there? (?) Later, Messier realizes that the characters the System assigned her to play are actually gender-swapped versions of superheroes from a completely different universe. Hidden CG 1: Tadpole Search for Their Dad (Locked) Hidden CG 2: Throwing Some Dust in Your Eyes (Locked) Hidden CG 3: The Richest Life from Scratch (Locked) Hidden CG 4: How Did I End Up Saving the World? (Locked) More hidden CGs to come WARNING: [The MCU in my heart ended with the old man's passing and a snap of the fingers.] The story still takes its time. Playing gender-swapped Avengers characters in the DC universe (severe OOC) [DC universe!!! Avengers characters!!!] The heroine herself and the superheroes are not in the same world (her world does not merge with the superheroes' world). The heroine knows nothing about superheroes, though she watches anime (there may be JoJo references, and crossovers with all sorts of odd manga and anime). When playing a character, the heroine acts according to her own understanding of the tags, which may differ drastically from the real superhero (more and more bizarre misunderstandings~). The System will be very prominent, and will often, intentionally or unintentionally, cause the heroine to develop strange misunderstandings about the superheroes and their world. Tag names differ from those in the blurb, but the effects remain the same. The heroine's secret identity will not be revealed in the main story. The pairing may appear in an extra, depending on how things develop. Theme: Know yourself, grow, and stop feeling lost.
