Hanging Out at Bat's House as Mafia [Comprehensive British and American]

After parting ways with Mr. Reborn, I was taken home by a wealthy man from Gotham. The other person claimed to be my biological father. Gee, am I so easy to deceive? ... Damn it, it seems to be true. I quickly accepted this setting and tried to live in harmony with a large family of brothers and sisters. They have a common secret they are hiding from me, but I don't care. Anyway, I didn't tell them that I joined a certain aquatic family and was a Mafia. I only care when Mr. Reborn comes to pick me up. As time goes by, I have no choice but to miss people when I see things. The old father pointed at the ring on my hand and said tentatively: "It's a good accessory." I honestly told him it was my engagement ring. Father: "... Who." I immediately became excited: "He is the world's number one killer!" I seemed to hear some crashing sound. In the background of the whole family preparing to go out to fight, only the father remained calm, thought for a moment, and asked: "Death knell?" Me: "What kind of cookie is he?" Father: "Don't use bad words and names." I held my face sweetly and said with a smile, "He is my Mr. R." ? ? Did I say something wrong? Why do they look like they want to beat me up? ! Things to read: *The text is not in the first person! *At present, I have combined DC and tutoring, and I will talk about the rest~ *ooc apologize in advance *CP is reborn *My sister had killed someone before, but she changed her mind after being brought home by the master. *Some desire for survival → Deathstroke is very good and very strong, so I don't mean I don't like him. My sister is just encouraging and speaking, and she can hallucinate a Harley Quinn (bu shi) Motto: Life is beautiful
