Gyokko, the current Vase hashira, he seems to care more about how good he looks and how the demon dies, rather than actually fighting. He uses vase breathing, (odd, I know, but it's useful.) Meaning his attacks are easy to break, and destroy, like a vase, but doesn't make him weak, like shinobu, his sword is laced in a lethal poison.

Gyokko was outside walking around currently, looking at flowers, trees, looking for demons.
