Boil Release: Unrivalled Strength

Boil Release: Unrivaled Strength is a ninjutsu fighting style used by the Five-Tails Kokuō and its jinchūriki.

Usage
The user increases the temperature of chakra to the, generating large amounts of steam and evaporating any water or ice in direct contact with their body. The pressure resulting from this emitted steam can then be used to increase the force behind physical attacks, giving the user. The exact amount of force produced is proportional to the quantity of steam released, as the greater the volume of steam utilized, the larger the pressure that can be built up. By releasing the pressure, not only the strength can be improved, but also the speed.

Improvement
Han wears special covering his entire body. The armour contains a furnace in its back, where steam is produced. The steam can be built up within the armour for a greater release, allowing just a simple kick to violently send an opponent reeling a great distance away.

Trivia
