Long distance flight, an optimized procedure
Required materials:
- Skywalkers
- Impulse seals
- Gliders
Of these three, only Skywalkers presently exist (talk about getting the hard part out of the way first). Impulse seals will have to be designed by Kagome because only he knows how to make directional explosions
[1]. Gliders can be designed by a civilian craftsman
[2] and tested by skywalker-capable ninja who are safe from the consequences of a failed design.
The procedure:
- Use skywalkers to climb high into the sky.
- Run in the desired direction and take out your glider.
- Deactivate skywalkers and activate impulse seals for extra velocity in the desired direction.
- Angle impulse seals to maintain lift, or alternatively scrunch up legs, activate skywalkers, and leap upwards to regain altitude without losing speed.
While skywalkers are necessary to the functioning of this paradigm of travel, it uses them much less and therefore saves large quantities of this vital strategic resource. Furthermore, with impulse seals providing extra velocity it is plausible for a ninja to achieve speeds higher than they could ordinarily reach with skywalkers and sustain it over long distances. Therefore this paradigm is ideal for high-priority messengers and elite, highly mobile strike teams.
[1] While directional explosions have been the default assumption for how impulse seals are to be created, they are by no means the only one. One of the two notable alternatives is sandbag macerators, storage seals abusing the ability to create exit velocities to generate thrust ex nihilo for a contained system like the inside of a bag. The other notable alternative is omnidirectional explosive seals in a frame that allows the backwards force to be vented into the air, thus still resulting in a net forwards thrust on the person using the seal. Both of these options have potential upsides over directional explosion-based impulse seals, so we must not discount them in our considerations.
[2] Akane's dad sounds like a good first choice, and if he doesn't feel like that's in his area of expertise he could probably recommend someone to us.
