Dark Release: Judgment

Hiruko converts the chakra absorbed with Dark Release: Inhaling Maw into light blue flames, turning it back on his enemies with amplified strength to blow them away.

Trivia

 * The technique's name is a pun, similar to certain techniques of Kumogakure-ninjas, in which it has an English name with a given kanji that somewhat match the pronunciation.
 * The light blue flames seen in this technique are likely a reference to the "Will-o-Wisp," as the "Dark (冥; kurai)" in "Dark Release (冥遁; Meiton)" means "gloomy; ghostly; night; underworld."
