I’M SO SO SORRY FOR RESPONDING SO LATE!!!! i don’t know any stl-specific accounts (as in, that’s all they tweet about) but i can direct you to some of my friends that love to talk about it, especially during chapter drops! apologies in advance if you already know some of them:

imane @shinkanes — if you’re an stl fan it’s almost a given that you know imane, she’s part of the team that fantranslates the chapters and has also translated some of takamatsu’s interviews in her spare time! imane’s a shining light and i love conversing with her about stl, if you enjoy my thoughts on it i’m sure you’d love imane’s!

lila @lilatheduckk — if you love shima and deeply analytical threads you’ll love lila! lila makes insightful interpretations of stl, which manifests in long threads or beautiful fics. there’s a good chance you already know lila, but if you don’t please especially look into her works! her grasp on shima is sooo good!

saz @nyoomzz — i think saz is best known in the stlsphere for her wonderful stl art, also for being the world’s greatest yuzumika truther (i am on her side). if you also like slice of life more broadly you’ll enjoy saz’s recommendations!

witty @some_witty_user — witty my friend witty… beautiful and fun art as well as the silliest tweets known to mankind, witty is such a delight whenever they tweet. they actually made a stl picrew as well! if you like silliness and fun art you’ll love witty!

liz @inumakiis — i love liz!!! i look forward to her tweets whenever new stl chapters drop, she also made some hit tweets iirc when the anime was airing (justly deserved!) i love her thoughts, i feel like they sometimes bring about a perspective i hadn’t considered before!

lena @ltejuns — my dear friend lena makes wonderful stl tweets especially about shimamitsu, i also love love love their coloured panel work, it’s beautiful! lena is always a delight to see on the timeline!

tine @egashiramika — i love especially when tine talks about the parallels between skip to loafer and kimi ni todoke, they’re super fun to read! they make a balance of silly and thoughtful tweets, if you’re also a big romance media fan you’ll really like their recommendations!

dante @dantiino — my mukai fan in crime… dante’s tweets about stl lend more to silliness, she never fails to make me smile! not to mention her wonderful art, ESPECIALLY MIKAMUKAI ART! if you’re a fan of mukai and silliness you’ll especially enjoy seeing dante on your timeline!

erin @egaoshira — when the anime was airing erin gave us the weekly gift of a mikacollage, which was a collection of screenshots of mika from every episode… i will always be indebted to her for that. erin’s a huge mika fan like me, so if you like mika you’ll enjoy seeing her! she also makes thoughtful tweets whenever there’s a chapter drop, and is just a wonderful presence on the timeline!

jenny @ultravioletjen5 — jenny’s first posted stl art included shima in the shinji chair and i just needed to follow her. jenny has wonderful art and is also super funny and thoughtful, i love what she has to say about stl!!!

nunu @nunuushi — nunu is so fun!!! their stl art is always a delight and you can tell just hoooow much they love it… i love seeing their tweets about stl whether they’re more silly or more analytical!!!!

lamb @lambcurl — lamb’s skip to loafer art is unbelievably good, i still feel a little starstruck whenever we speak to each other. their shimas especially are just the squishiest!!! i’m sure you would love love love their art!

cowla @carlota_point0 — cowla makes such endearing art and has such a rich insight and perspective on stl!!! i love especially reading their thoughts, they touch on topics that i wouldn’t necessarily think of and are just a delight to see!

kowpop @kowpop — kowpop is run by kkfvjkq and shisa, who i believe are long time stl fans! i know them best from their wonderful stl art and their mitsumi cosplays, both of which always bring a smile to my face!

joy @crumby_joy — WE’RE NOT MUTUALS but i LOVE their stl art SOOOOO MUCH, when they opened a store i literally bought out the entire catalogue!!! they’re also big on aslfua, so if you like both, you’ll really love their tweets!
