Also known as: 無明逆流れ
"Avidyāic Reversed Flow"
Signature technique of the blind swordsman Irako Seigen from Shigurui.
Performing this technique involves sticking the sword into the ground before unleashing it upwards in a single powerful vertical strike. The first part of the technique is often parodied in other works, with characters being depicted holding a long-shaped object pointing downwards to the ground while leaning their upper body and head almost 90 degrees to the right, similar to the stance assumed by Irako Seigen.
