Noblesse Oblige.

The Hachi vs Barragon combat consisted of naming a bunch of kido - ryubi no jumon, koko no jomon, kigai no jomon, hoyoku no jomon, shiju no saimon - which has no meaning to me whatsoever.(none of these has a number assigned to it, so they probably aren't a part of the Shinigami kido-learning curriculum either)

Anywho, here's the fight in laymen's terms:
Hachi trapped Barragon with kido, Barragon rots.
Barragon rots, Hachi blocks with the prism kido shield.
Barragon rots some more, Hachi strengthens his shield defense by enchanting and adding more layers and making it bigger.
Barragon says Hachi is stalling but does nothing more.
Hachi creates more shields and circles out of similar type kido that confines Barragon.
Barragon says Hachi is stalling but still does nothing.
Hachi has Soi Fon insert her Bankai into the chasm and shoot. Giggidy.
*note that all Barragon did was breath, talk, and stand x]

This chapter of Bleach reminded me of France's Maginal Line during WWII. I feel like Barragon could have just walked around the big shield and everything Hachi did would be for naught.
Also I don't know what Soi Fon has against Urahara, it makes it seem as if Urahara had experimented on her before without her consent because when she talks about it she avoids eye contact.
