You better have defense against machine guns, poison gas, and whatever Shinjiro and Yagi are packing. A successful raid would mean that the RAI will have guys on every corner. While you shouldn't be engaging the ships directly, they have heavy defenses.
I advise sneak attack, but those air vents are too small for humans and the corridors are straight and brightly it. Also, your RAI character needs to be competent. If he wasn't, he wouldn't be captain of the guard now would he? This does mean that basic precautions have been taken. The standard guard has nightvision, an assault rifle, anti-magic gas grenades, gas mask, combat knife, and body armor.
These guys travel in pairs and sweep up and down as well as left to right. Also, the captain of the guard should be well-versed in good prison guard tactics. These guards are supposed to be good at what they do.
I want to see you crush competent opponents.
Another option is a raid on a convoy. Were the RAI tank battalions retconned? If they weren't, you'll have to deal with a few tanks. For added challenge or audacity, they might store the target IN the tanks, though I see it reasonable for them to use a truck. If they use a truck, what are you going to do about the others you're not taking. That is a truckload of Gensokyoites we're talking about.
I was originally planning on makeing it more of a "smash and grab with a car thats armored like a tank going 200+ miles per hour, equiped with repaired and reworked military prototypes, and with the driver (my character) being an insane maniac" idea, but then a convoy could work just as well with less problems, plus makes more sense that we're just able to make to release 3 characters, and I still can use my escape chase scene too, and it would work with having the girls in tanks for this idea, insted of having a convoy truck, because when you think about it, all of the girls wouldn't be all captured at the same time would they?
Also, if they were to have gunships, would it be ok it one of them was a Hind D? this is just for the metal gear joke of Snake and Hind D's
And one last question, the artifical mana generators, the ones that are used to keep the captured girls alive, are these something like medical equipment that isn't easily moved, or is it something small and compact, and how many cats would one produce?
edit: and I'm going to need someway to pry tanks open without harming the people inside them, wait, I think I got it, and it fits perfectly to what I was oriiginally planning
Also, if people wanted to know why I was talking about military prototypes for the car, my character got them by fixing failed and old prototypes that are in the military junkyard, and most of this equipment gets like 5 shots at max or so due to several factors 1.limited ammo for that weapon 2. the prototype may have not been able to be repaired fully and will break at certain times, 3. possible other influences, as in unwanted matience by a kappa or sabotauge,
either way, the prototypes only go as a jet booster and some high strength armor plating, along with a super engine, either way, this stuff won't last that long in this RP, like half a day or so, and there will be catastrophic faillure of some of these prototypes at the worse points of time,
god I'm such a jerk to my characters at times, all so to see how I can get them out of the situation.
