Ayatana

The Ayatana is a Habit from the Legend of the Immortal Fathers. The sixth immortal father, the mind, sacrificed her life to seal humanity's wrath on Trading Day. Her spiritual energy, instead of dissipating, flits from mind to mind, searching for someone strong enough to restrain her energy. Only zeroes are capable of doing this, and those with strong enough Endo Null Energy to try and known as Holders.

The Ayatana is a wish-granter. Over the years, boredom has made her desperate for human interaction. What began as a spiritual power manifested over time to her full personality. She enjoys toying with her Holders, and it is her mind games that causes so many Restraints to fail, not just a physiological incapability.

Cero is her current Restraint.
