Man, that was a great chapter. Byakuran's strength is definitely in a class of its own. Even though its Tsuna vs. Byakuran, I still don't think this will be the end all, be-all of fights. I still believe Byakuran will obtain Yumi and get an even further power-up beyond what he has now (just thinking of that prospect is a bit impossible for me). How Tsuna and company are going to go against that, I don't know. Maybe adult Reborn will appear? Maybe future Tsuna will appear somehow? Don't know, but excited to see what happens.
