First, no matter how much I liked Switch before, he shot up my list today. I thought his background story was nearly over, but the fact that he's still roiling ratchets up his complexity. Switch is one well designed character who should really be a model for protagonists to come.
Second, I felt chills when Switch said
! he'll never love again. T_T
Seriously, Sket Dance is awesome… maybe more than Negima, TLC. ^_^
