Use special moves with an empty Hajike bar

It is actually possible to start a special move without any Hajike, but after it starts, it will instantly end.
In order to do it, fight an enemy with a Hajike-emptying attack (Such as OVER) Then, open up a character's special moves menu. Wait until your opponent uses their Hajike-emptying attack, and immediatly afterwards, use one of your character's special moves. The character will start the attack, but it will end immediately after it begins.
