Hard to say.
I'll outline some things we have to complete before this current 'mission' can be resolved.
1. Yukari needs to continue covering some information on the datacore. Just with the topic presently uncovered, there are some details that can be very useful to know.
2. Tom needs to complete the work he's doing on the ship's inner workings. This is important, seeing that was he is doing might be the only thing keeping Miharu together for a time.
3. Miharu will need to reach Nepleslia. Wazu will be handed over. I may need Tom's and Moonman's help with depiction of the Nepleslian authorities.
4. Somewhere along the line, senior officers on Miharu will need to meet to plan on what to do next, setting the stage for the conclusion of the Eve storyarc, Mission 5.
Miyoko and Takuma, I no longer know what to do with them. It seems that rather than help Yukari search, both have contented themselves with reading over her shoulder. The process would've been much faster if both had assisted, and reported on their findings. Itm was my attempt to try and open up the broader storyline being the Miharu's plot to more than just the senior staff's exclusivity... something that appears to have unfortunately failed so far in terms of involvement.
I owe Yukari a post. It'll be up by the time Doshii is back from vacation.
Wazu's matter is left presently in Nyton's and Sanjuro's hands.
I know Masako is considering working with the techs, but if Nyton can get in touch with her, they can try reorganizing their power armor teams following the addition of the newer recruits. Kyou, Tsuya, Kai, Masako and Nyton probably all need to touch base at least to get everyone properly outfitted with their own power armor.
