Alas, it's not pretty, but it shall suffice.
Having given up on any sort of fancy imagery and suchlike for the time being, much less any sort of classification... because, you know, the mun? Is kind of lazy. And now, in no particular order whatsoever:
future_hatsuneMiku's been very helpful and kind to him, explaining how the communicators work. At this point, he's very worried about scaring her off, so he's trying to not be his usual hot-blooded self. He does actually like her company very much, but then, he is secretly both fond of cute things (and she's quite adorable) and very weak to women. Currently a bit worried he scared her when he threatened Poland with a pencil. He's also not sure where he stands after their conversation about him being a nation, but is cool with her being a singing doll. That doesn't change the fact that he would stay his hand in a fight if she commanded it. (This is perhaps the only reason she ranks higher than Romano at this point.) He thinks she has a very nice singing voice after he got to play backing music for her. Also, he's officially decided that he'll have to harm anyone who enjoyed the accidental upskirt shot they got from the communicators during the gravity event.
mezzo_giornoIt's Romano. Finds him to still be the same loud-mouth insufferable brat he knows from his own time-line. Having said that, he does like talking to him, just because of all the arguing. Plus, Romano is fun to rile up. Though right now he's angry at Romano for bringing up art. It's a touchy subject, okay? Also, he now feels incredibly guilty about getting Romano killed during the ghost event. Apparently despite some initial lack of willingness to discuss it, and possibly a bit of fear and trepidation on both sides, they're mostly past this. Thanks to the truth serum, he's even more embarrassed to be around Romano, because apparently it's been noticed that his behaviour is very much like he's trying to court the older nation. Which he's not. At all. Nope. Not him. Especially not after Romano caught him flirting with his younger brother IT WAS AN ACCIDENT OKAY HOW WAS HE SUPPOSED TO KNOW CUTE LITTLE DEUTSCHERBUND WOULD GROW UP TO BE ALL TALL AND MUSCLEY AND KINDA HOT.
charinjo2Finds Gokudera to be a bit of a jerk. Still, the guy told him that he dies, and being forewarned is forearmed... He has since discovered that Gokudera, while really standoffish and a jerk, can be very helpful and informative. Especially in regards to the ID numbers. They'll have to compare notes on more things about the asylum at some point. Though he is a bit annoyed that he wasn't very helpful during the gravity event, they do get along somewhat decently. Even if he doesn't always follow what Gokudera is thinking. During the wings event, he was a bit entertained by Gokudera being so scientific about figuring out how to fly by watching Gilbird. While they still haven't discussed the asylum in depth, he continues to find Gokudera to be a useful ally. At least he gets why Prussia does want to meet with the people who have found the control areas of the asylum, and is willing to help with that plan.
thecutrperidotDr Annuska Simon. The enemy. The veritable Josephine to Linda's Napoleon. He hates her. He totally wants to get to know her on a horizontal surface, and we don't mean psychoanalysis on a special couch. Well, maybe hate is too strong a word, but he'd like her better if she weren't technically the enemy. However, he's willingly going with the whole psychoanalysis thing for now, because he thinks it will benefit him. Besides, he's gotten a good bit of information from her. He likes information.
ueberchargeInfuriating German man who thought it was a great idea to inform him that Prussia ceases to exist. However, he's a really awesome fighter, so he may be able to forgive him this eventually which may make him a difficult opponent. He grows less and less fond of the man the more he interacts with him, though there's a certain level of professional respect there. You do have to appreciate a man who is willing to cause awful and bloody death in the name of... well... anything, really. Science, it seems to be, in the Medic's case. (Though, he does think the man is stupid since he seems Hellbent on willfully ignoring things that are right in front of his face just because they don't fit into his criteria of what a 'logical explanation' is. And Prussia thought he himself had a narrow world-view..)
After suggestions involving cannibalism and a lot of scoffing from Medic about how they are all crazy, lying about things, cowards, etc. he finally got fed up with him and challenged him to a fight. Which ended in a draw, with both of them unconscious.
Oh, and then Medic kills himself over the communicators just to prove a point. But then sees no point in risking death to possibly gain information on how to escape the asylum. Prussia... is beginning to think any conversation he has with the man will invariably end in him wanting to hit his head against the nearest hard surface repeatedly.
uprisingphoenixIt's Poland. As far as he's concerned, Poland should probably be dead, and is honestly beneath his notice. Considering his government is trying to eradicate Polish culture in lands taken during the Polish partitions, it's entirely possible he actually wants Poland dead. He hasn't seen Poland in a while and thus can only conclude that the other nation is no longer in the asylum. Lucky bastard.
rules_the_east...It's Russia. He respects the man, but doesn't necessarily like him any.
unioneitaliaCute female North Italy. Hasn't had much chance to talk to her though.
de_bel_survivorNot quite sure what to think of Kouki at this point. He has been somewhat helpful, but at the same time... Prussia's not sure exactly where he stands with him. After a bit he did decide that Kouki was rather reliable, and definitely one of the more mature people there, despite not really interacting with him much. It's a bit of a shame to see him gone, because that means the supply of useful and rational people in the asylum is dwindling.
ro_eltyeirMiku's hot older sister... er, automatons can have siblings, yes? Well... if nations can he supposes robots can. Anyways! She's definitely reliable, and pretty awesome to talk to the few times they've talked, though he's not quite certain if flirting with her is going to get him anywhere. She was fairly helpful in blocking off the pool area after Medic decided to kill himself to prove there was a 'respawn system', so he has to give her credit for that.
hermaleselfWalks around in underclothes and is really rude. Um. Yeah, that's about it.
rea_nortonTeenage girl. Seems very eager to burn things. Could possibly be useful, but he hasn't really talked to her.
furgottenBABY CANADA OMG WHY SO CUUUUUUUUUUUUUUUUTE?! ehem. He's going to do his best to keep an eye on Canada, because he's sure France would appreciate it.
