oh, that was good.
Didn't see that coming. Sadly, since they aren't rings anymore (Except for Tsuna), probably the next chapters they will teach them, so they can use it in this form, and them they are going to have training, until the seventh day, when they are going to fight with Simon with both full powered "rings", but since are 4 vs. 7(Or 8, if they use Chrome against them) they will lose, and them Tsuna will get nervous, and he will scream en beat them in a fraction of a second.
And it's going to be awesome(Except for the training)
