Concealment Tag

Concealment Tags (隠蔽札, Inpei Fuda) are scraps of paper inscribed with a special writing, centering around the kanji for "hide" (隠, kaku). Infused with chakra, they are used by Yasu to hide things. When placed on an object or person, they become camouflaged.

Yasu uses this in conjunction with his kekkei genkai, Concealment Release. Since the release can only work on himself, he can use the tags to allow others to share his ability. However, unlike the release, people with the tags can still be found by sensor-type ninja. Yasu mostly uses this tool on people, as he can use his release on objects he is holding. However, if he does not plan on keeping the object with him, he may place a tag to keep it concealed after he leaves.

When activated, the tags become blank pieces of paper. If removed, the hidden person or object will become visible again.
