The perks of having Shiro as an ally mean that you will want for nothing and always be given the best. Need a star chart the size of a room? Well Shiro will just take the room for you. Need a method to not die? Impress her and Shiro will offer you the ability to save your life amd even help you become a god. Despite all her flaws no one can say she doesn't treat her friends and those that earn her respect well.
