Black Sun (Gen Nakaido24)

Black Sun is a powerful ninjutsu harnessed by the power of the chakra within the realm of Ten-Ja. Using the power of the Guardian Beast Chakra Form, the user gathers as much chakra as possible and creates a sphere above their opponent, compressing it into as small as a sphere as they can. Once the sphere reaches critical mass, the user lets it expand into a burning orb of massive size and intensity and drops it upon their opponent. Despite not coming in contact with anything, it was said that the sphere would've been enough to drill unassisted into the planet and destroy anything at its point of impact. The sphere can generate powerful winds beneath it and cause blinding darkness within its vicinity. The chakra has so much saturation, it can pull other chakra into it to fuel it further. The chakra used is so great, it cancels the Guardian Beast Chakra Form and eats away at the users own body, preventing them from ever using it again.

This is Daigaru Meitochi's most powerful technique in Kimza Chronicles, and it was only rivaled and dispelled by Sanhiro Kimza's most powerful technique.
