What the Hell Is Wrong with This Aotu Contest?

Hello, everyone. My name is Weiya, and I'm a transmigrator. I was just an ordinary student, but one day a windfall suddenly dropped into my room, and I got a transmigration experience thrown in for free. Once I was ready, I arrived at the Arena with my health-monitoring System. Being as clever as I am, it didn't take long for me to realize something was wrong. Weiya: "System! Get out here!! Tell me why all these canon characters are looking at my lovely lower back with such creepy (perverted) eyes?!" System: "Wake up and work hard. Keep improving every day. Stop thinking about such unrealistic things." The blurb may be misleading. Read with caution. The heroine is weak at first, but she's not stupid. Don't read if that's not your thing. Pairing undecided OOC warning I'm very busy. Updates will be irregular until school lets out. There might be several consecutive updates, or there might be a long break. The chance of updates from Monday to Friday is especially low. Read at your own risk. Coming soon: Today, I'm Still Matching Wits with the Undercover Agents Adopted as a child by the head of a certain Port Mafia, Watanabe Akiri has already unilaterally accepted the unscrupulous Mr. Mori as her dad. She devotes herself wholeheartedly to serving the Port Mafia's interests and has an excellent work ethic. At twenty, she receives a mission from her "dad" to investigate a strange organization of black-clad people who use alcohol as their code names. Watanabe Akiri sets off without hesitation. Under the pretense of friendly cooperation between organizations, she becomes a temporary member of the "real liquor" ranks, helping the never-seen boss with various tasks while following the clues to gather information. Unfortunately, the people in the organization aren't very friendly. They constantly test each other and hide knives behind their words. One slip and you'll be tricked into revealing information, and there's always some listening device on you that you have no idea where it came from. There's no sense of camaraderie at all. Compared to this place, the neighboring Vongola is practically a group of angels. Later, after spending a long time at the distillery, she makes the complicated discovery that aside from the traitors, everyone there is an undercover agent. A few others are just muddling through, while the hard-working Gin spends all day keeping the organization running and purging anyone who doesn't belong. The problem is, a few of the new friends with whom she's painstakingly built a revolutionary friendship are also undercover agents. Watanabe Akiri: Wow. This is terrifying. This organization is bound to collapse sooner or later. Home really is the best. Ever since that bastard Dazai Osamu defected, everyone has worked together in unity and harmony to build a bright future for the Port Mafia. It's absolutely true, not a word of exaggeration! Tachihara Michizo: Haha, is that so? A chaotic mashup of timelines Crosses over with Bungo Stray Dogs, Katekyo Hitman Reborn!, Detective Conan, Fate, and a bunch of other minor characters Maybe also The Disastrous Life of Saiki K.?
