hey and sorry for the late response but thanks so much for asking! i haven't met too many people who're both into adashuada and umineko myself and seeing that they do exist is always exciting~

i'm also glad you enjoyed that RS answer, hehe. i don't interact with fandom much so i've always believed my interpretation of umineko to be somewhat subjective. happy if people agree with it 🔥

[spoilers below]

if i'm honest, my favorite adult from the very start was Kyrie, haha. i adore her design, her general demeanor, and seiyuu. so in ep7 Tea Party my brain went "well-well, do we ever not get automatically attached to the villains, huh?" :'> not like umineko doesn't make any major adult a villain at one point or another, of course. but i think Kyrie is the only one whose flaw is revealed to be near-sociopathic attitude, where she holds nothing dear except herself and her future. i mean, one could say her heart-shattering drama was having Rudolf and Battler stolen from her but.. she doesn't really grieve her husband when he's dead in ep7 massacre and says 'welp, now i don't need Ange, cause i only needed her to get tied to that man, yay'. i love villains and all, so this entire twist didn't make her completely uninteresting for me - i still love her psycho chessboard brain, tbh. bu-ut i do wish she ended up being more multifaceted, haha.

for instance, the way Eva's and Natsuhi's personalities are explored throughout the game is on an a whole other level entirely. their major flaws aren't justified/negated but you still feel sorry for them and understand where they're coming from, admitting their humanity as a result. (especially Eva's - she's my second favorite). even Rosa - one of the least likeable adults for me bc horny abusive mother with abandonment issues - gets something akin to a redemption arc in manga's ep8, where she finally remembers herself as a kid and apologizes to Maria.

my third adult favorite is Ikuko/Featherine. she's odd in a fun way, rich-unmarried-recluse-writer (=life goals) and occasionally shares some good thoughts on the reader/writer relationship which, i assume, is Ryukishi's own thinking.

oh yeah, men exist too. Rudolf's womanizer status feels like a bad joke, Krauss is just a stressed and insecure child most of the time (he kind of grew on me after ep4 and 5 though) and Hideyoshi is a ray of sunshine in this entire family who did nothing wrong (except maybe agreed to kill people for money in ep1 and told his son his lover was dead).

the main blocker for my love toward the "servants"' gig is "why the hell did you not persuade that child to use all that money to get a surgery and leave this cursed island to find happiness outside this family?!". i guess the real root of the tragedy is both Genji and Nanjo being submissively gay for Kinzo and obeying the Ushiromiya head like their lives where at stake there or something...

speaking of the culprit - i love how intricately Yasu's worldview and perception of reality is shown in both the novel and the manga. the 'confession' chapters add the necessary nuance to the reality situation which was only implied in the game - and it's a very important part of the angst, imo. Ryukishi likes to say in the interviews that the motive for everything was 'love' and that those who didn't experience love wouldn't believe in/understand Beato's extremes. but despite being a romantic, i'd agree that if a reader only sees Battler's broken promise as the reason for the "killings", everything can feel like an unhealthy overreaction. it's all much deeper and more understandable though when you take into account the very specific and seemingly unsolvable depressed situation Yasu was in (including the "we're all related???" part of the things). the nuance hinted to in the game and explored in the manga really helps to better understand why exactly they felt so cornered and why they went for the "murder"-suicide.

thanks so much for asking about this forever-favorite masterpiece, anon! and feel free to drop by to talk in person in DMs if you ever feel comfortable :>
