Not to gatekeep but yes, this isn't meant for some people. You will hate the MC. Even I found this guy annoying and unbearable. Yet I still felt intrigued on how his story will end. Every character felt real and well done. Though I wish there was more options to interact with each character. Dokudami's other ending made think I could influence others the same, until I found out I couldn't :( After 100% the gallery and achieving all (4) endings, I was expecting that this would be a longer game, but oh well. You still have your imouto. Be happy, genuine, and empathize with other people. Remember that you are not alone, Mai Pen Rai bro, Mai Pen Rai.
ok. the author at least is self aware but, ♥♥♥♥♥♥♥♥ is the read such a slog and so self important just because you know dostoevsky, dazai, hemingway doesnt mean you know your literature--especially since you just mention ♥♥♥♥ by name and not even go talk about *why* you mentioned them in the end i guess the writer knows this as well but idk maybe the point of the protag is to be insufferably pretentious? at least the little sister knows whats up and actually tells him art is good, game concept is super nice, but the writing i just kept having to roll my eyes id still recommend it though, but unfortunately the only people whod actually think this was deep were people who have also a shallower understanding of the literature
All ending Complete 8/10 Even though it’s a relatively short story it still has some really great messages It’s a shame we didn’t have enough time to really get attached to the characters, but the fact that it managed to develop them this well in such a short amount of time is pretty impressive.
I had an enjoyable time reading Sister Other Paranoia, delving into the mind of a cynical protagonist who is afraid of the outside world. He can't seem to form real connections with acquaintances or friends, and keeps everyone at a distance — a man who cannot trust other people, and whose distrust feeds directly into his fear and paranoia of the outside world. He relies on his telepathy to get to know people rather than trusting them. Overall, the novel leans on philosophy and tries to make the reader see the world from the protagonist's perspective — specifically, how he places himself above other people simply because he can read their minds. That said, the novel lacks meaningful character development until very close to the end. The true ending is unlocked by clicking your sister's forehead after playing your first playthrough. Judging by the CG gallery, the coworker is the only side character who gets a happy ending; everyone else reaches their own bad ending as a result of their own circumstances — the one exception being that the MC does actively push each of them toward suicide. In the true ending, I understand that the protagonist needed to open the door, step outside, and learn to fully trust someone without reading their mind — to not see people as black and white. Still, I don't think Nyalra delivered a visual novel that truly stands out. The writing itself is strong, and I came away understanding the MC's perspective. However, it did not clearly distinguish itself through its world building or characters. I feel the game lacks substantial development as a visual novel. The characters seem to exist mainly so the MC can project his own insecurities onto them — his inability to trust anyone (including himself), The interactions between the MC and the side cast often feel abrupt and don't flow smoothly. The coworker's arc is a good example: one such as the MC, lost in his own elaborate thoughts, then it cuts to the mc's coworker simply wishing he could be free of his dead-end shop job, then cuts again to the MC suggesting to the coworker that he should rob a yakuza-run store — with nothing bridging how a quiet wish for freedom turns into a suggestion of robbery. This pattern is captured well in one of the game's own visuals: the MC is depicted as a lighthouse at the center of a web, with each side character reduced to a small animal portrait caught in the strands around him — the coworker as a monkey, the senpai as a bat, the parents as a ring, the crush Botan as a fox, and the childhood friend as a caterpillar. You hover over each panel in as a spider UI with your mouse, which suits the MC perfectly: he never truly want to help each character due to how the progress of each short character's story eventually crack until broken; Botan spirals into suicide from the main character due to her devaluing her own self-worth by sex-dating older men and hides in a fanboy club that worships her like a queen; and the friend never escapes the confines of working for a company until he "flies free" by jumping off a building; and the coworker, who eventually died to consequences of the main character's suggestions to rob a yakuza office; and the senpai can never write a rookie published novel due to his insecurities and the inability to be genuine, drowning in a river nearby because the mc couldn't give him real critique; and mc's parents who eventually hate on each other until they kill one other due to them cheating on one other. In every case, it's the MC's mind-reading, not just his silence, that does the real damage — he talks each of them into their ending, his influence amplifying their despair until it tips into suicide, or in the parents' case, murder. There's even an implication that his sister might be the MC himself, since the only voice he ever hears in his own head is hers, saying "Onii-chan." It almost reads like an autobiography of Nyalra, about learning to see the world as it actually is instead of filtering everyone through your assumptions without getting to know them. Not to mention, the protagonist realize that happy endings are not so bad after all in the true ending. Then, where the hell is my happy endings for each of the character in the second playthrough. Why only the coworker? Conclusion in the true ending does feel unsatisfactory due to how little time we get to spend with the sister. Overall, this didn't meet up to my expectations. Pacing suffers because each character's arcs to resolve so abruptly without sufficient content to build those characters. Would I still recommend it? Yes — but I expected more, having gone in with high hopes after the demo. I thought this would be a 20-30 hour visual novel that deeply explored each side character, especially Botan. Even if it still ended in tragedy, I would have preferred a story that beautifully fleshed out each character's thoughts and behavior through the mind-reading mechanic. Honestly, I expected content that goes into each character's perspective when interacting with the main character for a second playthrough — not a short game that the main character learning to trust himself, coming to accept that humans are morally grey or complicated creatures. Sigh, I am disappointed, though.
