Sage Art: Playhouse Sealing Technique

Through the use of a scroll and a chakra infused area, one can make an exact replica of the setting they infused chakra into (in a similar manner to the Shadow Clone Technique) and seal it into the scroll. This sealing technique, as stated by Hayato Shin, is more of an accommodation. He uses this to keep some of his Ninja Cats safe while he battles, until it is time to summon them, that is.
