O.S. That
O.S. THAT
 * Shaman: Green Garam
 * O.S. Type: Spirit Type
 * Spirit Ally: THAT
 * Medium Used: Playing Cards and Magical Staff

Description: By integrating with a deck of cards, THAT can generate a multitude of cards and manipulate them as it sees fit, such as creating a wall of cards that completely camouflages those behind it. The cards can also be launched as projectiles.

Anime/Manga Difference
THAT only appears in the manga and the 2001 anime series, but not in the 2021 anime adaptation.

In the 2001 anime, THAT is called Devil Clown and its appearance is a bit different. Green Garam used this to attack Lyserg.

Trivia

 * The name "THAT" is probably a nod to It, the titular supernatural, murderous clown of Stephen King's novel.
