Fire Release: Blazing Explosive Kunai Maelstrom

Known as Xaverian's signature move, this technique was used by him first in the Chunin Exams, which resulted in the quickest recorded knockout. Later on it was used regularly by Xaverian, especially in his vigilante days.

The trick to the effectiveness of this technique is by disguising the insertion of the explosive tag-ridden Kunai (while coating the kunai with a thin layer of chakra to prevent a premature explosion) in the Fireball technique. This is usually achieved by distracting the enemies with Shadow Clones, or by simply reducing visibility with smoke bombs, before launching a savage volley of fireballs from behind the smokescreen to the opponent.

When the fireballs reach the opponent, they begin exploding simultaneously, sending tiny metallic shards of shrapnel from the kunai at the opponent. Besides that, the area around the opponent becomes a miniature inferno, reducing mobility. Another variant of the technique is to unleash a flamethrower at an enemy, only to reveal the explosive kunai at the very last minute, as synchronised explosions pummel an enemy.

As with many of Xaverian's attacks, this attack relies on sheer unpredictability and raw simplicity. It's success depends on the intuition and largely on skill of the user, as a minor misstep or error in chakra distribution could result in the kunai exploding in front of the user.
