Best Division/squad in Gotei 13
Id have to say that Division/squad 11 is the best in soul society. i base this on the fact that the 5th seat of squad 11(Yumichika Ayasegawa) can defeat a vice captain (Shūhei Hisagi, aquad 9), and that ikkaku (3rd seat) has bankai.
Also the vice-captain from squad 7 (Tetsuzaemon Iba), was originaly from squad 11, but transferred to the 7th Division so he can be a vice-captain. Renji Abarai was also a member of squad 11, buit and become vice-captain of the 6th division/squad. This would imply that squad 11 has powerful people, that are not vice-captains, that could fill in vice-captain positions in other squads.
squad/division 11 is just baddass.
