Akyuu: I never forgetting things seen once... And I record the history of Gensokyo. She was silent for a while then continued. In Gensokyo, youkai are the enemies of humanity. This rule must be upheld as an undeniable truth. If we don't, everything would fall apart at once. Our entire society is built on a delicate balance. She is talking about her philosophy while introducing herself.

She is a pitiful person with a short life span... That all i can say, but it seems Akyuu has surpassed that limit.
