Cards

The Sealing Cards are a set of cards that is able to generate all five of the basic elemental chakra natures. To do so, the user needs to seal their chakra in a card, and in a mental command, the card transforms the chakra into one of the chakra natures.

These cards are also used for Haru Shinagawa's techniques, which involves the use of the chakra natures and creating more elemental offensive moves.

Trivia

 * The user does not need to have the certain nature. For example, the card can release fire even if you used Water Release chakra on it.
