Wait, is she the tail of the Big Boss? Let me see if I can remember what manga this is.
It's a seinen but it seems to match a bit http://www.mangago.zone/read-manga/yakushoku_distpiari_gesellschaft_blume/
Nope, but I did manage to find it. I went to baka updates and searched the acrobat category. I was thinking of Michibata no Tenshi, but you might of given me something else to read so thank you.
Recently the memory of this one shoujo manga has popped into my head and I went to see if it was ever finished. It's about a troop of orphan acrobats that act like a family. The girl gets adopted into the "family" and likes one of the guys. At the same time she's wanted for inheriting some power or something. I can't remember the name and would love to find it again.
