Information is the most crucial for strategy, is what dad always says, he also always says better than nothing.I am not only a saiyan who only knows how to battle, but I am also the son of a strategist.It may be necessary to prepare myself for a long drawn out battle and come up with a plan outside of battle.Since the brat is also a native of Gensokyo, she should know the ways of Gensokyo, thus rather than killing her letting her live might be better.I understand to the extent that under those circumstances, I am cannot screw up.
