Lava Release: Melting Apparition Technique

Mei releases a large amount of lava from her mouth, which spreads into a broad, thin sheet as it travels through the air. Since it is shot upwards in an arc so as to descend onto the targets from above, it prevents the intended individuals from jumping up to avoid the attack. A great deal of smoke is created afterwards by the effects of the lava, so should the targets still be alive, a follow-up attack can be conducted while their vision remains obscured.

Trivia

 * The phrase is a pun on the Japanese words  and.
 * In later episodes, the lava produced by this technique appears closer to its manga adaptation, with colour and texture much like its rubber variants while maintaining the same corrosive property.
