Rare Kind

Rare Kind
Rare kinds are people with the ability to negate the special powers of others. They are unlike other power users in that their lost form requires an exlir to restore their orginal form. Their blood is also needed to open pandora's box.

Powers
Ability Nullification: Rare kinds have the ability to negate the special powers of others. It seems that this power is in their blood as Shibuya's costume is coated with his blood and special powers cannot affect the costume as well. Another example is that the new school building was built with shibuya's blood mixed in, making it so that special powers couldn't be used in the school.

Shrinking
It seems that when a rare kind over uses their power they shrink to a small doll size. This is unlike other "lost forms" in that after 24 hours they still do not return to normal. A special elixir made with the blood of a rare kind is required for them to return to normal. Rare kind's power are not only defensive, it is also offensive. They are capable removing the source of one's ability along with their life, killing them eventually. Rare kind are actually naturally cruel, heartless and ruthless. It was said by Yukihana, that Rare kind have no evil or dirty intention, like a new born baby, they just don't know and understand the meaning of life. They are just like that.
