Yūsumi Gugenka: Byakugō Yachihoko

After drinking black ink from the Stone Bowl of Buddha, Inogei's mass increases eight times over, making his body eighty times as dense. Despite his density, his power, speed, endurance and chakra is increased eighty times as well, putting him roughly on par with a used of the Eight Gates. The most notable increase, as noted by the user, is the sheer increase in calories within their body, increasing eighty times as well. The ink effects secondary effects will then kick in, causing the ingested ink to change from pitch-black to pure white, causing a spiral to appear on the users forehead. As the symbol appears, all of the users excess calories are converted to chakra, literally shifting the users already high volume of chakra up one hundred times more. The ink also causes a reaction within the body, fusing all Yin and Yang chakra produced into chakra.

This causes the user to be surrounded by a fine, glowing white aura, which is actually visible chakra. In this state, the user is able to instantly generate ink and use it as an extension of their mental prowess and physical body. It allows the user to see the name and form of anything within their field of vision, even if they are normally invisible, viewing their form in an manner almost as if they were artistically drawn in detail.

After the technique is completely activated, the user's ink turns invisible, only being capable of being viewed by the user, being seen as white ink, though the Byakugan is capable of viewing it. Because of the user's vastly increased chakra, the user gains a healing factor, devoting a good amount of chakra to their cells, causing them to divide and the cell's telomeres to regenerate, effectively allowing them to heal any and all wounds, regardless of severity until they exhaust their chakra, working in a very similar fashion to Tsunade's famed technique. The healing effect is so extreme that it will remove the name and form of foreign objects and materials embedded within the user before using their energy to increase its healing effects.

One the excess chakra within the user is exhausted, the users normally chakra quantity will be untouched, though the user will required immediate medical attention afterwards and rest for a period of anywhere between 2 weeks to a month as their body is entered into a semi-coma-like state. The shock to the users system can be treated with specific medical procedures within the.

Sadao Uchiha eventually killed Inogei with Ryōiki Shinkengen, essentually manipulating the future to where the technique merely failed, resulting in Inogei's death, despite Yūsumi Gugenka: Byakugō Yachihoko capabilities and power.
