[Western Crossover] Fighting Bruce Wayne for Custody of His Son

In her last life, she dug up her mother. In this life, she became a mother. Gladys, who had always used any means necessary to complete her missions, accidentally got bound to the Holy Mother Mary System. Now it was her turn to be a mom: she had to win over Gotham's stray birds with love and challenge the previous bird mom to complete the miraculous mother mission. Someone who had never been a mother before: Can I win them over physically? 023: ...Whether you win them over or not isn't the priority. First, adopt a white Labrador, then adopt the little birds. That way, there'll be someone to keep the household in order. 023: This is a challenge mission. Since you're here, you have to challenge Gotham's strongest bird mom in history, compete against her, and meet your KPI. Gladys: Who is it? 023: Batman. Adoption is a small matter. Victory comes first. With nothing in her eyes but KPIs and the urge to win, this woman would stop at nothing to complete her mission. From then on, she embarked on a one-way road, battling Batman, reputed to be Gotham's strongest bird mom, for custody of the little birds. But why didn't that little bird named Jason come slash her tires? Had Batman stolen the chance for a carefully planned run-in? 023: Maybe your car isn't fancy enough. How many cars in the world can outclass the Batmobile? Gladys suffered defeat after defeat, only to fight on again, breaking down all the while. Her adoption progress remained at zero. 023: Maybe it's not just the car. Maybe it's you. Who could possibly not love Bruce? The System guiding her through the mission didn't even bother pretending it wasn't a pure Batman fan, and her friend was an excessively devoted Bruce fan. Gladys grew more and more convinced she was losing her mind. Kids, the enemy is right under our noses. Is there still any chance of completing the mission? * Wayne, in Brucey-baby mode: Jason, what does your mother talk to you about? Jason: Fuck Batman! Wayne slowly turned his head and shifted his gaze to the young woman beside him, who seemed gentle and friendly and had always gotten along well with him. A few question marks slowly appeared over his head. Who could have guessed the woman across from him had another identity at night, one that had also had a run-in with Batman? Do you know how awkward it is to transmigrate through time with Batman and end up imposing on the Waynes? Do you know how fun it is to take a vacation in the neighboring Avengers universe with Batman? Do you know... Do you know what to do when your son dies? With most of the adoption missions stalled, 023: Marry Wayne. He'll be their adoptive father, so by extension you'll be their adoptive mother. That counts as completing the mission. Gladys: ... 023: You keep saying “Fuck Batman.” That's profanity, isn't it? Mind your language. Gladys: That's not profanity. 023: ...Damn. Note: Pairing is Bruce. Mainly DC. Theme: In a contest with no clear winner, love will be the final answer.
