Fire Release: Sacred Nakaido Blood Detonation

This technique is the ultimate technique of the Nakaido clan. Known as the "final Nakaido jutsu" by many, this is a suicide technique used to wipe out enemy forces when overwhelmed and as a means to protect vital secrets.

First, the user bites into each of their thumbs until they bleed. Then they draw a complex symbol on each of their forearms. Then the clasp their hands together and begin to gather fire chakra, when enough chakra is gathered. The user makes three hand signs and the user creates an explosion that rivals the power of Deidara's C0 or even surpass it in some aspects. The explosion is a dark red that consists of blood and the blood proceeds to ignite everything it touches. The user usually clears out their comrades before setting off this technique and the symbol is only a means of stating the clan's legacy, as the jutsu can be made with only the hand signs. This jutsu also kills the user, who becomes the medium for the explosion.

Gen Nakaido started to use this jutsu twice, to kill Issaru the Guardian Beast and to finish off Otoshi Nagare. However, he was spared from his death both times by intervention of some kind.
