Jet, Three-Stage Thrust (ジェット三段突き, Jetto Sandandzuki?) is the Noble Phantasm of Okita Souji.
A miraculous blow caused by over-boosting the jet-pack's internal super engine, MAKOTO Drive.
The three-stage thrust is unleashed at sub-light speed level by means of transcending jet acceleration to exceed physical limitations to cause an event saturation in the local space, and it was originally an attack meant for a single target, but it surrounds the target and annihilates unlawful power.
Due to the over-boosting exceeding the limits, it randomly becomes inoperable after activation.
