[Comprehensive British and American] Funny Gotham and the Centenary Bat

Bruce Wayne met Gotham - the consciousness of Gotham City - when he was fifteen years old. It was a pleasant conversation, even though he was about to leave his home, the world, and the world... Gotham: Make a deal, you protect me and I'll protect you. Bruce: Oh, okay. Then Bruce never grew taller. Bruce: ... What's going on? Gotham: There is no difference between you and me. You won't grow up. I won't destroy your immortality~ Not long after, a British magical savior was stuffed inexplicably. Bruce: ... Who is this? Gotham: A certain famous kid whom London gave to me to protect x So Bruce and Alf worked hard to raise the child. In the process of fighting criminals, he was teased and bullied in various ways, and then he adopted three children and then got a biological son. So this is a Batman who looks fifteen years old but is actually forty, and is a hundred-year-old Buddhist on the inside. Bruce: ... Is it still too late for me to return it? Gotham: It's too late~ Batman center, main cp super bat, deputy cp details. Slight allergy and bat-narcissus tendencies though? Rich bestie group x The timeline is very confusing, don't get hung up on it. The author is a little idiot, slow to update, rubbish writing, serious OOC, irregular work and rest, unhealthy...
