Another character specific trophy. This one must be done with Rikuo Nura. He's the character with long white and partially black hair in the kimono and the sword that you first complete story mode with. This can be done in any mode aside from training, however it is highly recommended you do this in local versus with a second controller.
It's strongly recommended you do this with a second controller because Rikuo is another character who has a "counter" move. His is a bit easier than the others, however, because he doesn't harm the opponent when he counters. That said, pick he and another character and start a fight. Move the second controller all the way to the right and stand right beside them. Tap
with the second controller and Down+
with your primary to counter. This should teleport you and land you in front of them again. Simply repeat the process when you land 100 times and this will unlock.
