Heat Seal

A simple technique that allows infuses the seal with the symbol 暑 (Atsu, Literally Meaning: "Hot") with Fire Chakra. Once activated with the tiger hand seal the seal begins to heat up to extreme levels. If placed directly on an opponent's flesh the heat from this technique could easily leave dangerous burns, as it is roughly around two hundred degrees Celsius. Once activated the seal will continue to emit heat for around five minutes, whereas it will cool based on the material it is placed on (Metal will cool quicker than materials containing high amounts of water). While this seal doesn't have an opposite removal seal designed to remove it, any equally powerful seal removal should be effective. Sakyū has been known to separate opponent's from critical tools by applying this seal onto an opponent's weapons.

While this technique can become quite hot, it usually isn't dangerous unless to an opponent unless they come in direct contact with the seal. For example if the seal is placed directly on the opponent or onto a material that conducts heat, which is in direct contact with the opponent (Like metallic weapons). It should be noted that this seal is invisible to the unaided eye until it is activate, in which it glows a bright orange similar to liquid iron.
