Um... Aside from Bu-ling and An-nin, it's gotta be Bu-ling's dad nano da! Bu-ling hasn't seen him in a long time, but that's 'cause he went off to train in the Badlands! He's probably fighting monsters and sitting under a waterfall and living on a mountain and doing cool stuff like that no da!

Who do you think is the coolest, Isa-oniichan?
