Synopsis.
College student Sorawo Kamikoshi, in the midst of engaging in her hobby of urban exploration, stumbles upon a strange door in an abandoned building which leads into the Otherside—a mysterious and terrifying world seemingly populated by locations and monsters from internet creepypasta and urban legends. Sorawo nearly dies in her attempt to explore it, but is rescued by Toriko Nishina, a young woman who is skilled with guns, more experienced in regards to the Otherside, and is looking for a lost friend. Sorawo and Toriko, spurred by the payments delivered by a researcher named Kozakura, return to the Otherside to bring back artifacts and deal with the monsters best that they can. As time goes on, the two are increasingly affected by the byproducts of being involved with the Otherside, meet some humans who are trapped within it, and find themselves increasingly affected by each other.

A sophomore at a university in Saitama Prefecture. She loves and has a wealth of knowledge about urban legends and real-life ghost stories. She enjoys exploring abandoned buildings, and discovered the existence of the Otherside through a door she found while doing so. She doesn't have many friends, but Toriko, who she met in the Otherside, invites her to go there to explore, research, and earn money. Her mother instantly died in an accident, and her grandmother and father became devoted to a cult afterwards, causing her to repeatedly run away from home and explore abandoned houses to escape her disintegrating family, which was persuading her to join the cult, but after her grandmother and father died, she is now attending college on a scholarship.

Her character in the story is very positive, but she has a tendency to isolate herself from others, and has no friends other than Sorawo and Satsuki, who was Toriko's tutor.

 A researcher of the Otherside who has a residence near Shakujii Park. A friend of Satsuki's from her college days, she was concerned about Satsuki's investigation of the Otherside because it was dangerous and had warned her many times. When Satsuki ignores her warnings and continues with her research, she goes missing, which makes her angry and frustrated with Satsuki. When Sorawo first meets Kozakura, she looks so young that she gives off the impression of being in grade school, but she appears to be older than Sorawo and Toriko, and is shown drinking and driving a car. As a hobby, she has created an avatar named on the Internet and has been streaming videos. The image of Yozakura is based on that of her friend Satsuki. In the past, she created another avatar based on her own image, but destroyed it due to the increase in the number of fans who disagreed with her intentions. For Sorawo and Toriko, she is a client of the goods they obtained during their exploration of the Otherside, and is in the position of a consultant. The artifacts that Sorawo and Toriko have acquired in the Otherside are purchased by Kozakura, while the funds to purchase them are provided by the DS Research Encouragement Association, a research organization that Satsuki and Kozakura joined to conduct research on the Otherside.

Reception.
Constance Sarantos of "CBR" says that the series breaks the mold of the yuri genre, avoiding common stereotypes of the genre and creating a unique narrative, defying, in their view, "expectations for a yuri anime" as it delves into the horror genre and has a "Relationship built on crime and survival" rather than a slice of life about "interpersonal romantic drama." Sarantos also said that the series shows how well the sci-fi and yuri genres can mix, combining themes of fear and romance, something which isn't often used in yuri anime, with the protagonists having to "work together to defeat frightening foes". Even so, Sarantos stated that while the anime doesn't "deconstruct the yuri genre" it shares storyboarding which "emphasizes intimate moments and loneliness" with "Bloom Into You", "Just Call it Love", "Fragtime", "Liz and the Blue Bird", and "Adachi and Shimamura", among others, utilizing the "emotional scenery one would expect from a yuri series". In that respect, Sarantos said that it is similar to "Kemono Friends" and "Girls' Last Tour", adding that there is an expectation it will "nail the aesthetic of yuri" even though it is an "unconventional yuri narrative". 
Reviewers for Anime News Network shared the sentiment of Sarantos. Caitlin Moore called the series "one of a kind" and a welcome addition to a series of yuri anime about "teenagers falling blushingly in love for the first time", with neither of the protagonists, Sorawo or Toriko, based on stereotypes. Even so, Moore said that the chemistry between them "could have come through stronger", called the visuals a "mixed bag" and said that there has been "a real lack of queer genre fiction in anime" recently, meaning she is "all the more excited to explore it". James Beckett, on the other hand, said that he was only lukewarm to the anime and said that while he is "not asking the show to answer all of my questions upfront", he would like "a little more context" and that he hopes that it "manages to live up to its potential". Similarly, Nicholas Dupree said that he feels the show lost him the premiere, even while he called the two protagonists a "charming central couple", and can't "click with the episode as a whole" while Theron Martin was more positive, saying that the series could be "worth watching" just for the interactions between the two protagonists. Just as positive was Rebecca Silverman, saying that the series was fascinating and creepy, saying it will likely be a faithful adaptation of the yuri manga it is based on, while saying there are "a few little missteps" and would like to know more "about the whole urban legend/internet myths piece" too. Hannah Alton of CBR argued that the series stands apart from the "usual fare" of the isekai genre because it is a yuri series, with the protagonists not trapped in the other world, but can easily move from the real world to the fictional world known as the Otherside, with the danger within the Otherside, which is "populated by monsters from Japanese urban legends" which can't be killed unless someone looks directly at them.
Alton further says the two protagonists stand out in the genre, with Sorawo as a college student who "keeps to herself" and Toriko who is experienced at using a gun, something which violates existing Japanese law, which tightly controls firearms. Alton concludes by saying that while the anime falls into the isekai genre, it is different "from the usual high fantasy adventures in empowerment." Others have praised the anime, along with "Moyasimon" and "Genshiken", saying that this prove that college anime can "offer a different take on "coming of age" storylines than the standard high school tropes" while focusing on "serious adult issues" like interpersonal conflict, struggles over identity, and mental health. Additionally, Christopher Farris reviewed the anime's fourth episode for Anime News Network, noting that the vibes and ideas of the episode fit the series, while pointing to inconsistencies with the storytelling, and stating that within the theme of fear, everything else "works wonderfully", praising the sound design and how it taps into people's fears. Jordan Ramée of GameSpot praised the anime for starring adults, unlike most anime, calling it a "a refreshingly wonderful series" which has a "pretty cute and wholesome romance".
Erica Friedman had a mixed view of "Otherside Picnic", which she reviewed on her blog, "Okazu". She praised the novel series as "an overt mix of Japanese netlore, science fiction, action and horror tropes and a big scoop of Yuri", but she was a "little disappointed" in the anime, specifically criticizing the animation style, disliking what she described as "comedy-action" in the series, and the pacing. Even so, she called the anime "very enjoyable" and praised the voice acting as "superb". Ultimately, she called the animation "unsatisfying", said the story was not "compelling", criticized what she saw as "pointless service" in the series, and said that the anime "feels like a children's version of the novels", giving the anime an overall rating of 7 out of 10.
Silverman reviewed the "Otherside Picnic" manga for Anime News Network, writing that it does not have "some of the issues that
