right, so... getting back to this, some things (with some subtle differences) from the drama cds applies are as follows:
as already stated, minako viewing and openly referring to the owners of the bookstore as her grandparents; even going so far as to check on michiko after bunkichi's disappearance into tartarus is reported, keeping her company and walking her home until he's rescued. thereafter, she visits him in the hospital until he's made a full recovery.
additionally, bunkichi's misconception that her and ken are "long-lost siblings" is something she comes to acceptβif not occasionally teases ken about from time to time.
lastly, this dynamic applies to maiko as well, who normally referred to her as her "onee-chan." her enjoyment of this is also partly responsible for bringing about the idea to be viewed as her counterpart's older sibling despite being the same person and soul.
it might be a trivial detail, but the station outskirts was not the first and last place she ran into shinjirou. they also reunited at the summer festival that same year before he joined their cause, where he fixed the strap of her geta after aigis accidentally snapped it (fittingly enough, a broken geta is believed to be an omen of misfortune according to japanese superstition).
she's very briefly met elizabeth in passing, leaving her unfamiliarized with her personally as opposed to what she's heard from plenty of theo's horror stories.
getting dragged into student council busywork also meant tagging along with its members and her classmates to school at night to ward off fellow students trespassing for the sake of testing their courage. while the involvement of ghosts made the situation a little hairy for some, she actually found the experience quite fun.
after takeharu kirijou's murder, pharos nearing the final stage of his ongoing metamorphosis started taking a temporary toll on her health, causing her to suffer from frequent fatigue, headaches, nausea, dizziness, and at worst fainting spells. unsurprisingly, she tried braving through it all in order to put her teammates at ease to little avail. she didn't let this stop her defending the dorm and her family of friends from the kirijou security department's raid as well.
the last point brings me to the next: her teammates were also subjected to the kirijou security department's search in regards to seizing the late ikutsuki's things, although this went nowhere subsequently to not just akihiko but her shutting their efforts prior to this raid down as well.
despite dorm rules, she's snuck koromaru into her room for a sleepover before. specifically when the dorm's security system inexplicably malfunctioned and locked its residents in for the night. despite mitsuru being made aware of this, the circimstances at hand during that time canceled out her getting scolded for it.
in further relevancy to the prior point, she still doesn't have a full understanding of that incident since she quite literally decided to just sleep through the event like a stone. she's fully aware of what happened during the cyberattack on the security system from months before this though.
and for future reference, i also want to put a heavy emphasis on s.e.e.s. interacting with others that isn't solely restricted to the main cast either because it's something i really, really like. minako's family of friends have met her other friends and in a franchise whose staple is about forging friendships and human connections, i think it's a very important element to include here.
