Stage 3 boss. Half human, half beast.
Has the ability to eat (conceal) histories, or to create them.
The first of two abilities belongs to her human form, the last to her beast form.
She's usually in her human form, so that is her "true form". She transforms into a hakutaku
during the full moon, at which time all information is known to her. When the full moon disappears,
she feels a little sick to her stomach.
Ever a friend of the humans, she protects them from Gensokyo's many youkai.
There is not one thing about the history of Gensokyo that she does not know.
Abilities: Able to eat (conceal) and create histories
Keine looks like an ordinary human most of the time, but transforms into a hakutaku under the light of the full moon. In human form, she can only conceal histories, but in hakutaku form, she has full control over every aspect of Gensokyo's history and can create new histories at will.
When she first noticed an abnormality in the moon, she decided to seal a nearby Human Village during the night in order to protect it from youkai.
She devoured the village's history to make it invisible.
Although Keine is not human, she loves humans and always tries to help them. She only uses her ability when it would benefit humans.
