Did I Do Something Wrong by Starting a Business War in Gotham?

Kakaya transmigrated into a cyberpunk world as a child and grew up listening to the business legends of Arasaka Corporation. Ambition grew inside her, and she dreamed of going head-to-head with this megacorporation. Unfortunately, she still died. After death, Kakaya went to Hell and was banished to its lowest level. A System called "Universal Megacorp" bound itself to her. Its slogan: "We buy, we develop, we expand, we **." She grinned. All right, all right. Then... I won't hold back. At a meeting, Constantine said, "Bruce says you're a Hell-born entrepreneur, but you've come to Gotham to wage corporate warfare. If you mess around in Gotham, you'll be seen as a supervillain. Bruce won't let you wage corporate warfare. Are you going to do it anyway? Hurry up and answer." Kakaya: "We'll do it even if it kills us." Constantine: "What if Bruce catches you and you end up on bad terms?" Kakaya: "There's no way we'll fall out. We're just doing a little corporate warfare. It's not even illegal. We started a band, offered a bit of credit, made a few acquisitions, and wired up every soul in Hell to generate electricity, with the power lines going straight to the graves so everyone visiting a grave can charge their devices. Would he really hold a grudge?" Constantine: "Bruce caught you waging corporate warfare. He was very serious and told you to stop." Kakaya: "It's fine. Gotham has so many industries. Can he keep an eye on everything? How could he watch us all the time? Once he's gone, we'll keep at it." Constantine: "What if he catches you again? And he really hates you pretending you weren't doing anything. Since he caught you, he'll be sure you've been sneaking around." Kakaya: "I'll just smile. A really awkward smile. Hold my head and give Bruce a very awkward smile. It'll definitely work. He'll have his eyes wide open, and the moment our eyes meet, I'll start laughing." Warnings: 1. The blurb is badly written. The main plot is the female lead waging corporate warfare everywhere. The side plots are adventures, dungeon runs, and chaotic daily life. 2. The female lead is a chaotic, free-spirited menace with no CP and no romantic interest. Nobody acts seriously. The story focuses on friendship and family. 3. This is a wild-idea crossover stew. You can read it even if you haven't read the original works. Theme: People need to work hard to achieve something.
