And every infighter who can put in enough rotational energy through their hips can do the vacuum butt canon.

Keijo does not appear to be a series where special moves are secret or even unique (maybe hypnoboobs...).

The difference is can a girl use a special technique without hurting herself, or ending her career prematurely.

Edit: The UTM exists for a reason, and it isn't just to punish misbehaving girls. The instructors know how to make super moves viable for the appropriate girl.

Think of Keijo less as a fighting series and more as a wrestling one. Girls might have Signature Moves, but they're not unique and they never pretended they were.
