Just using Fight Queen as a test for practicing boxing manga. It's The Flaweless Butterfly vs. Fight Queen. A few changes were made to the dialogue to better fit into the manga.

Fight Queen is a manga story about a girl named Tsukiko Kurashi who gets beat up on purpose in order to study her opponent's moves only to come back with a one-hit K.O. in every match that she fights. Sometimes, she's lucky, sometimes she's not.
