[Tachibana]

Spoiler for 49:

Let's see, there is only Tsukune, Mizore and Kurumu left that have yet to fight, perhaps Kurumu and Mizore will head back to take down the 6th subdivision leader, the reason why i say Mizore and Kurumu is because it looks like its their time to fight, while Tsukune and Rudy proceed forward, but that still leaves two subdivision leaders left (still excluding Miyabi), so now it would be that time for reinforcements to start arriving, unless Tsukune is able to take them down himself or that Ruby has had time to heal to join him, but the reinforcements will arrive when it reaches a critical point, it's nearly to that point.
