I am very impressed with the most recent episode, 202. If I understand correctly, essentially this entire Time Tsuna and his guardians have been fighting with inferior rings! Yet they were still able to fight against the Funeral Wreaths and their full powered Mare Rings. Also, quite a lot was explained in this episode. I was never very fond of the whole parallel universe idea, you just can't have a character like that... in theory, he should have had access to powers and knowledge limited only by one's imagination, God-mode. But at least we finally got an explanation of it, as well as the mystical presence of the previous-generation Vongolo all this time. I'm much more willing to accept the parallel universe thing, since it fits much more nicely into the story than I thought, with this revelation.
Not to mention the epic battle. I was very impressed by Tsuna. I kept dreading that Byakuran would reveal some other epic power to counter Tsuna, and he did, but it wasn't quite as epic as he thought. The only thing I could ask for now, is what the "flame voltage" on that last X-burner was! It would be nice to have a numeric gauge on just how much stronger Tsuna has become, because I imagine it would be absolutely incredible.
