Lava Release

jutsu are techniques that combine fire- and earth-based chakra to create a torrent of lava that can melt away almost anything. This chakra nature can also manipulate other related materials such as lime, which is an alkaline powder, rather than molten rock. Lava Release is used by the Four-Tails, its jinchūriki Rōshi, and is a kekkei genkai of Kirigakure's Mei Terumī and Iwagakure's Kurotsuchi.

Trivia

 * When Rōshi's Lava Release is first referred to, the kanji 熔, with the radical for, is used. In later references when Mei's is used, the kanji 溶, with the radical for , is used instead. When Kurotsuchi used it, it was once again with the fire radical. This seems to indicate that the Lava Release from Iwagakure uses the fire radical, while the Lava Release from Kirigakure uses the water radical. However, in the data and fan books, both kanji have been used to refer to Rōshi's Lava Release.
 * Nowadays, the two kanji are synonyms and used interchangeably, with 溶 being the more common variant. However, there seems to be a subtle difference in meaning between the two. The kanji with the fire radical seems to be used more often in words relating to metal and other solids, whereas the kanji with the water radical is more often used in words relating to liquids.
 * This kekkei genkai element shows the most different users with no known blood connection to each other.
 * Lava Release shares the same romanisation as Yang Release.
