No there really isn't there are two girls who are immune to it though, once you unlock the disinfection bay though. It completely removes all negative effects from your girls without using all your precious resources for purging kits or bytes from buying them.

Is there one in the memory room? And he who is in The ship aside from statistics...

you use organic cores to refill it, that or you use the fuel cells but you gotta enable them to be able to use them in place of organic cores.

I honestly don't think it can avoid well I think its probably a matter of preference, it adds more features for certain things some of the mutations aren't visible it just tells you what it does while some are visible. You can't really interact with your teammates they interact with you or the other members in your team randomly, or just say their own things sometimes I do kinda wish you could, but you can't interact with your waifus they're just kinda there. Yep I think its pretty obvious you use the monsters to do that sometimes the monsters will randomly attempt to do it and sometimes they succeed the same with Sasha some monsters are more aggressive with this than others with this while others aren't, other times you need to use certain seduction skills to raise their climax rates which make it easier to get Sasha and your girls pregnant like slutty seduce for example is a good skill to use for that and soaking bottom raises pregnancy rate for Sasha. yes despite its name mating call is an attack not a seduction skill well I haven't gotten that far but I would assume that she can't because the Choco horse can't do this either only sash seems to be able to use the Futa mod at least as far as I've seen i would assume that this feature is enabled in the second game but not this one. do everything all the side quest you're able to do this should help with what you're missing this includes rescuing Christy and making her part of your team and just keep doing it with the monsters to slowly unlock everything as well you can make all your prisoners of war into your team mates as well by crafting solutions and doing things with them until they decide to join you just go into the hold and craft solutions from monster parts.  To get into that one planet's base in galaxy 4 you'll need the Futa mod enabled as well to do this you'll need to disable the sex animation in the mods once you do go find the tentacle monster in para ark or one of the various planets that has it and wait till it does implantation once it does click next then click observe also you can disable this and re enable auto sex animation in the mods section press z simultaneously in the Hud once you get into your inventory to cycle through it to see all the mods you have unlocked usually the mod is already enabled when its acquired.

You recover tp by using guard or by using skills like love touch that regen a little or a lot of tp per turn, or both theirs other skills that also give tp  which you can also use but take pw to use or might not it depend on the skill your girls might also have a skill for this but I mainly use these two methods.
