Day 5 art of the 'Josu Challenge'.

Ox Guard: the most complicated but perhaps most versatile guard of them all, a powerful thrusting stance that can also be used to parry, the Ox is infamous for its lightning quick, long lunges. It's aerodynamic form allows any knight to blaze through the fields without sacrificing any of its offensive or defensive capabilities, on ground or airborne. While using it efficiently requires a very high degree of precision, those few who master this stance are a force to be reckoned with.

It's a thrusting stance, so Bonnie doesn't use it.
