Nakamura - herta space station researcher. Subject of study: biology esp, marine lifeforms. Got also assigned leviathan study
Icchan - an octopus that should have 1-2 years of lifetime. Since Naka has his heart broken by Hirose-Hana at the time, he used all his braincells to lengthen the lifespan of his friend. Somehow researched immortality for octopi
Matsumura - herta space station internal auditor. Still annoying and has paid multiple ppl to get Naka's pic as usual. "Annoyed" Naka to the point that there are two swivel chair in Naka's office behind his table
Hirose - a subordinate of Dr Ratio, also a teaching assistant of sorts. Also full support of his two friends being a cringy disaster
Mukai- also a researcher. cyborgs so he can fanboy with grandpapi Welt
Takeuchi - security personnel under Arlan. At some point became friends with Naka. Bullied by both Naka and Mukai when they can. Goes to Naka for help for matters of the heart
Yuuka and Okuda- both in HR. Founder of Matsunaka Club. Became famous enough in the station that it has a grp chat with bets and also a Matsunaka spotted moment with pics/videos if they can get away with it. Footage from the security cameras may or may not have been involved
Kawamura - artist famous in The Blue and Planarcadia. Bullied sometimes by Nihilux for free food.
Tamura - famous director on The Blue. Comes to the station sometimes to annoy his beloved blue haired witch. The trusted director to show the greatness of the Inimitable Beauty on screen
Aokiyama - a researcher on magic. The occult club now has scientific and financial backing. Best research station ever!!! Also still kidnaps Naka for experiments with her bf as her conspirator
Oomori - still assistant of Tamura. Also helps with Hirose when he has a free time then caught the attention of Ratio. (Too thin and too skinny, you need to eat and exercise more)
Hana - a coworker of Matsu. Awkward at first because of Hirose. But she became his close confidant abt his Naka issues. Got up close to Matsu's tendencies. Full support since she is also a friend of Naka (became friends in HS), even if she wishes Matsu lowers his intensity. Main contributor in the grp chat
Matsu and Naka met again on the station. Matsu was very mesmerized at the view of Naka in space. Had to be caught multiple times for stalking and paying someone for Naka pics before he actually realized he was in love. Arlan was worried but had to let it go since Asta was very entertained
Matsumura usually goes for surprise audit and to annoy Naka on a not-date
Asta, Arlan and Peppy are members of the shippers. Asta is a top commissioner for fanarts
One time, they went on a funded research on a nebulae. There were rumored space whale bones (idk the official name in hsr) there. Accompanying researchers were sick of how sweet they were on that trip lmao ("no we are not together stop asking that!" "not together yet hehe". "do not believe that dumbass!")
Naka frequents Lushaka as it is a water covered planet. With Matsu as his (uninvited) company
Naka at one point got on an argument with Herta. He was worried he was gonna get fired (with dozens of breakdowns) only to get promoted as the Peerless Gem is impressed. Matsu heard and was to the rescue, which became a congratulatory party afterwards. (With an almost kiss????)
Himeko visits Naka when she has time for trailblazing the way of coffee mixing. The two somehow enjoy it. Matsu is a frequent victim.
Naka is the closest thing one could say a trusted subordinate of RuanMei. With him sometimes being worried with her staring at nothing or sudden discussion showing what a mad scientist she is and having nightmares after
Naka and Hirose are best friends here. With Hirose fanboying at Danheng, Naka with full support. Someone is unhappy at the background lmao
Kawamura has impressed the Genius#83 with her Art which is why she can go to the station sometimes. Hangs out with the other fujo grp and Naka when she can. Also has decent profit from the station ( esp from Asta) due to the fanart commissions. Has lost some of the money due to scams (She is very grateful to her senior for all her help to become the artist that she is today, so she helps when she can. Too bad Nihilux never learned proper financial management)
Hirose and Oomori will gain lots of muscles due to Ratio's mandate
RuanMei has also assigned the two as babysitters of Stephen Lloyd when he is on the station to varying sucess. Stephen secretly adores this two while bemoaning outloud they are embarrassing.
Naka is a friend of Caelus since he was along there when he first woke up. He will be sometimes assigned as TB watcher (do not touch that trash can it contains deadly chemicals wtf!!! And no you cannot enter the maintenance-waste room). Matsu is not a fan
Takeuchi and Mukai had a raise after the invasion of the station because no one died on that day. Take was then seen limping the day after. Which is a mystery since he should have no injuries during the invasion. Also Mukai was all smiles at that day which was also weird. They were put on separate topics in the general gossip grp chat
Matsu and March also has discussions abt photography and such. March noticed a lot of the photos is Naka. She too became a club of member of the shippers
When the Geniuses have need for a brainless discussion, they default to this two. Screwllum and Herta is quite invested
Matsu invited Naka on a date on penacony. Naka is impressed/annoyed by the audacity. Then Sunday happened lmao. ( They may have been on the same dream with multiple kids that can form a basketball team. Naka was still preggers before the dream got forcefully cut)
There was quite a lot drama on the iron tomb campaign. Naka along with Mukai has an expertise on space weapons which fascinated Matsu previously but he doesn't want Naka to be on frontlines. (Cyrene was also a fan of this two and hopes to personally visit the station eventually to observe the disasters)
There might have been memokeepers that Herta caught at the same time with the memosnatchers but she let them go since they were after mundane memories not Nous.
Also Herta might or might not have a hand on having some of Matsu's confessions going badly, to continue the entertainment as it were. Screwllum shakes his head in exasperation each time.
