Beat the Twins. Level 65 on Normal. Was tricky and I had did some swapping to bring in Ann for Matarunda on the Twins and eventually had to swap out Ryuji for Yusuke for Masukukaja to finally get those last few hits in.
There where multiple occasions where Hassou Tobi whiffed on one of them. Yoshitstune is not a guaranteed win by any stretch of the imagination.
He kept missing that much in the end i had to keep the one low on hp and work on the other.Then pray it hit both when they were low. ---
