A Sister's All You Need

Every day is full of fun. But something is missing. "My life would be amazing if only I had a little sister. Why don’t I have a little sister...?" These are the musings of little sister-lover and novelist Itsuki Hashima, who only writes works featuring little sisters. Around him gather a number of unique people: genius author/pervert Nayuta, female college student Miyako, illustrator Puriketsu, and the brutish tax accountant Ashley. Each of them hold their own worries, but live their peaceful daily lives while writing novels, playing video games, drinking alcohol, and filing their tax returns.

Even though the title suggests that this is an incest, sister-obsessed Eromanga 2.0 but no, it's not. This anime is totally different. Most of the people must've put this anime on their "Won't Watch" list just by reading the title, but if you have reached till the reviews to check out if this is actually an incest anime, then you've done a good job. This anime is NOT INCEST. Its just that the main protagonist, who is also a light novel author, is a siscon. but fortunately he doesn't have a sister. Throughout the series, he just fantasies about his imaginary little sister, and write it as a novel. This anime is a mixture of slice-of-life, comedy, a little romance and...... ECHII. No no, not little sisters nor underaged girls saying "I love dicks" casually. All the characters are adults except the protagonist's brother who is a high schooler. The adults are like, naked sometimes (ofc girls only) and their excuse is "I can't write unless I'm naked~ Pehe~!"  This might be your favourite anime of all time, or just an average anime passing through, but believe me, just give a try.  Story (8/10)This anime is about some light novel authors, how they live their daily life with their own difficulties and happiness. The story was beautifully presented. This is one things i like about light novels, is that the whole series is based on how they present the story in mere words. It is really intriguing -every episodes ends in a cliffhanger- and makes you eager what happens next. All is interesting but, there were a lot of board games, which are just games and nothing else. No progression, just like a filler. Animation & Sound (7/10 & 7/10)Nothing much in this area. The OP and ED were really good and i never skipped them. The BGMs were ok too. But i really like the Voice acting of the characters, they were well done. Characters (9/10)The whole anime revolves around the characters, and heavily depends upon them. The story moves forward as characters develop. No characters are left out, everyone gets their time to present themselves to the viewers. The interactions between the characters is what makes the comedy and the story moving. Overall (7.8/10)This is nice, chilling and relaxing to watch. The BGMs and the characters set off a nice chill mood, accompanied by the low contrast animation. If you like slice-of-life comedy about light novel authors with some pinch of romance in it, then you should try this.ALSO PLEASE, PLEASE SKIP THE FIRST 3 MINUTES OF THE FIRST EPISODE. If you're piqued, then ill tell you why.  NOT SO HUGE SPOILER, but hey its my job to say it.They just show a story he wrote about two siblings (a bro and a sis) with his weird imouto fetishes. A little hint : the lil sis will be fully naked in the whole scene and the bro uses her bra like a towel after bathing and eats her used panties (not joking here)


i ain't a fan of light novels, i'd rather stay clear of them, especially if they had the word "sister" in the title, i'd avoid it like the plague, just by reading that word in the title, i can imagine what it'll be about, a sleazy deviant incestuous fan service-ish fantasy, which is something quite common in LNs. why do such shows fail miserably most of the time? because the sister is fetishised, and the subject and the themes of the incest relationships are never explored in a mature or a meaningful way. to my surprise, the show didn't have actual incest, instead of that it just has a light novel author with extreme levels of perversion who loves to write incesteous fantasies. jee, it's light novel trash about light novels, LIGHT NOVEL-CEPTION . it can never get cringier than this. But wait, it sure can! The first three minutes of the episode were showing what kind of story our author is writing, and it's seriously fucked up, whoever wrote this thought it was a good idea to have a strong first impression on the audience, but the result is so creepy it ends up having the opposite effect. You can say it's a joke with the purpose of showing how crazy the protagonist's way of thinking, or how much he takes his little sister fetish. But here is the thing, if it was a joke then nobody is laughing, it's pure cringe. And anybody is excused for dropping the show after it, Even if the show wasn't really about that. The show is mostly a comedy focusing on sex jokes and deviant sister fetishes jokes. i'd be fine with the show if that's what it was about, Haganai is another light novel adaption by the same author, and it's mainly harem/ecchi comedy. it's not only about that, it's also trying to have an insight into the light novel publishing industry, something that would be great if the show was more serious about it, but it's not because it's more focused in the comedy. a thing that i appreciate from this show is having adult protagonists and no school settings, it makes for a fresh experience in a Copy-paste medium, where every show is following the same formulas without adding to them. The characters arem't just one note archetypes, they have their own internal struggles and conflicts. But the problem is that the show's mood keeps swinging too much, and with them constantly used for fan service and sex jokes, it's hard to take them seriously. you might say that the presentation is just optimistic, if it was realistic and focused it would be depressing and boring. here is the thing, there is a difference between light and humarous, and between cringy and stupid. Another positive is the decent production values, the show looks and sounds great. And that's all the positive that I can say about it. it's not exactly a bad show, but with terrible first impressions, so many tonal shifts, and tons of fan service, the negative ended up overshadowing the positive, and it made it so it can never be taken seriously, while still trying to take itself seriously, so i can't say it's more than average.
