Clarith Oak/History

History
After Akuma attacks Viridian City, Clarith falls into another world, where she is found by Klaud Nine thanks to Cross Marian's infomation. She learns to trust the female General.

Three years later, when Clarith is 15, she gets an order from Komui to help Allen Walker, who is in Asian Branch. She meets Bak and Allen here, then goes to Edo with Allen. With Charizard, she helps Kanda to beat Tyki, which makes the Noah of Pleasure retreat. However, Kanda thought he was an Akuma which Tyki called up and tried to attack him. Allen stops him from doing so at the last second, but Kanda gets mad. Not yet, they start arguing.

When Lenalee is suddenly dragged into a warp that opens in the ground, Lari is one of the several who reaches after her and gets sucked in, as well. When the group (consisting of Lenalee, Allen, Lavi, Chaozii, Kanda, Krory and Clarith) awakens, they are inside of Noah's Ark, something that she automatically threatens the Earl's Golem - Lero. The Earl then uses Lero to taunt the Exorcists, telling them that the Ark is collapsing and that they will all die inside of it. Tyki arrives shortly after and offers them a key, inviting them to play a "game" with him before throwing the key, which Kanda catches.

Once they have set foot on stable ground, the group makes a pact to escape alive, which Clarith refuses bluntly, before they use the key to open a door and enter a "room", where they are met by Skinn Bolic. Kanda stays behind to fight him, and the others continue on.Not long later, Clarith and the others find a library, where they encounter Jasdevi, a pair of twin Noah As they fight, Allen loses the key and Jasdevi use their ability to create illusions, making thousands of copies of the key, all littered across the floor. Lavi receives the task to find the true key, which he sudceeds. But Krory stays behind to find.

When the remaining members of the group reach the top of the Ark, they meet Road and Tyki, learning that they have less than an hour left. Eventually, Clarith encounters Luke, her childhood friend. Unfortunately, he is brainwashed, which means they have to fight, a Pokemon battle.
