Probably my favorite technique so far >,>
A technique where one would open 4 portals around oneself, a meter away. A large amount of Keigoku then flows towards oneself, and enters ones system and fills ones Tenketsu with Keigoku. This would literally turn me into a solid manifestation of Keigoku, and allows me to travel through the portals we open (since I am Keigoku z,z). Of course, this means I can only use Taijutsu, and it also gives a bonus to Tai (+15). The technique has drawbacks, like hindering myself to just using Tai, if I use it for longer than two turns and no S rank Nekura techniques, when this is active.
It's great for them sneaky attacks, and when the opponent is already hindered, but also great to dodge some of those deadly techniques, since one becomes intangible in a sense, and you can also do some sneaky shit, since opening portals is silent. Overall, bad ass >,> I remember Better used it against me once.
