Kotono was an orphaned girl who was taken in by the priest and now adopted father, Joshua. The case of the missing children hit close to home for Kotono, this made her work harder to find the missing kids.
One day, she got tangled into a mess with the masked villain and ran into Ewan, who magically put the "Justice" Tarot card into her body. This allowed for her to turn into loli black, and defeated the masked villain, who eventually was found out to be Herlock.
Kotono's transformation involves Kotono in an ancient greek type of attire, she grabs a sword and pokes it through a strange flesh like ball. A mucky ooze crawls from the sword, onto Kotono and falls to the floor. The muck turns her white outfit black; as she transforms, she says the following.
Kotono: The light of Foundation. That sleeps in faith. A sacred power that atones for sins! Release the chain of corruption! Grant me now, your guidance! Sacred! Loli black is here!
Judgement - Judgment negates a cards power, destroying the card and freeing it from the user.
Black Belt Ribbon - Strands of black ribbons fly out of the crystal in Kotono's sword, and latch onto a person to stop them from going anywhere. It can also be used to burn the victim, after being caught.
