Sage* Mode (仙人モード, Sennin Mo-do)
Senjutsu, No rank, Supplementary
User: Jiraiya
The lion-like child of the toads is overflowing with spirit!!
Wielding the "senjutsu" that surpasses ninjutsu!!
The form form Jiraiya showed to use senjutsu during his decisive battle with Pain. He summons the Two Great Toad Sages from Mt. Myouboku into his body and by borrowing their power, his body absorbs a great amount of "nature energy". By kneading this with his own chakra, he gains the ability to use senjutsu (仙術, Sage Techniques), rapidly increasing the level of all techniques, be it ninjutsu, taijutsu, or genjutsu!! By uniting with the Two Great Toad Sages into one body, they can cooperate like a Trinity. This is certainly the domain of Sages.

→↓He Draws a line under both his eyes using his own blood. Using this as a substitute for the "contract seal of blood,"** he can summon the legendary Two Great Toad Sages into his own body.

*Sennin (仙人, "sage") are a kind of immortal super-humans from Chinese and Japanese mythology. They are basically humans (or the spirits of humans) that have lived as hermits and have become so great that they gained the power to perform certain miracles and became immortal. One of the most famous Sennin is the Gama Sennin, or Toad Sage, from whom Jiraiya got his nickname.
**Keiyaku no Keppan (契約の血判); the blood one needs to sacrifice before summoning something.
