I'm no expert when it comes to competitive. Based on my research on Yatagaryu though, it seems Timid (for more speed) and Modest (for more damage) are the most appropriate natures for it, and I settled on Timid. It's a special attacker so having 0 in physical attack shouldn't matter (I think).
The common moveset seems to be Thunder/Dragon Pulse/Nasty Plot/whatever with 252 SpA / 252 Spe / 4 HP in EVs.
EDIT: Uh I just read your post more closely, RED is the bonus and BLUE is the penalty. It's high in speed and low in physical attack.
