In theory, this seal can be applied on any target. There are, however, some restrictions:

• both the user's and the target's Chakra Signature must be identical, and neither must currently be affected by any ability damage, fatigue, exhaustion or movement-impairing effects.

In practice, however, this seal is almost exclusively used on one's self. It allows the target to ignore the penalties coming from aging for the duration of the seal (1 year). When the seal ends, the target will suffer 1d6 points of temporary Strength, Dexterity and Constitution damage as well as be Nauseated for 2d6+2 hours. This technique uses three seal slots on the subject's body, which will be freed once the seal's effects fade.

Expendable Components: A fair quantity of the user's blood used to cover part of the target's body in symbols. Scribing the seals requires a Craft (calligraphy) check (DC 25) to be made, not necessarily by the user, and takes 5 minutes. If the check was failed, the sealing process will fail without the user noticing until the end.
