NOTE: MODS DELETE IF INAPPROPRIATE. Seeing as how this technique was OK'd to print in Weekly Shōnen Champion by the editorial team, I think it should be OK(?)
Google "Gaia dark tunnel" to find out what the technique entails, I am not linking it here.
Anyhoo, this is a specialized assassination technique used by Gaia(Grappler Baki) that was developed for people of small size. And it is brutal AF. It involves Gaia hiding in a sofa, the target sitting on the sofa,
and Gaia pulling a Xenomorph-like move.
The question is, who can defend against the Dark Tunnel once they have already sat down on Gaia's sofa?
