When four half siblings wished to be a family and made a deal for it to work, they never thought that they would be adopted by the Batman of all people. Although it's not as if being the charges of one Bruce Wayne is an easy thing, they also have to struggle with sacrifices they've made and conflicts that seems to arise at every turn... not to mention the already complicated problems the Bat Family currently have. An overly affectionate acrobat, a supposedly dead rebel, an insecure genius and a demon brat of many skills and pride. Collab with Star_Gazer51 and KuroHitsujiDreams
