@Falbium_Asmodeus: I see, but you should also remember this about characters in Negima: For the most part, they're highest DC is only Mountain level +, even Jack Rakan wasn't able to break island level along with Fate and Negi. Buranchi is considered on par with someone like Zebra, who could obliterate Cooking Island if he wanted to, which is a total of 18,000 sq kms. Basically the size of New Jersey, although a bit bigger. Buranchi isn't as strong as Zebra of course, but he's fighting people that are around that level. As for the barrier it would most likely pose a problem for a time, but his stronger attacks like his lightning sword or his secret technique could possibly break it. Once it's broken, it seems to need time to recharge again.
