I was expecting more from the gender bender theme itself, but this anime turned out to be another 1000th comedy about girls doing cute things. All elements related to the topic of gender reassignment, simply drowned in this moe-nya-comedy. In general, just another work of many similar ones, someone will like it. And I'm just disappointed.

Almost rated it a 7, really, I was wondering for the first 2 episodes where this was headed, if it even had a goal, and well it turned into a CGDCT with a gender bender/guys point of view flavor added, and it was quite nice.
The season ended with 'The End' so I guess there will be no season 2 ? that's a shame because I felt there was a lot more to explore and it wasn't all that deep either.

Comedy? Yes.
Slice of Life? Yes.
Getting turned into a young girl as a part of your sister's science (& secret) project might sound like a horrible fate, but this series kinda obviously go the comedic every day life route. Because of this premise, it becomes a story about new perspectives as the protagonist gets to experience being a girl. It tries to charm you with warm colors, “smooth” & moe animation, lighthearted atmosphere with some heartfelt moments and slow burning comedy and also acts as “education” on how to be and live as a girl.
Whether you like the characters or not is what is going to break or make the series for you because of the heavy SoL. If you are not into gender-bending stories then I would suggest you stay away since they do remind you constantly that this is actually a story about a dude.

female, , agoraphobiaAgoraphobia is an anxiety disorder characterized by symptoms of anxiety in situations where the person perceives the environment to be unsafe with no easy way to get away. These situations can include open spaces, public transit, shopping malls, or simply being outside the home. Being in these situations may result in a panic attack. In severe cases people may become unable to leave their homes., humanModern humans are the only extant members of the subtribe Hominina. Together with chimpanzees, gorillas, and orangutans, they are part of the family Hominidae. Terrestrial animals, humans are characterized by their erect posture and bipedal locomotion; high manual dexterity and heavy tool use compared to other animals; open-ended and complex language use compared to other animal communications; larger, more complex brains than other animals; and highly advanced and organized societies., introvertIntroverts are people whose energy tends to expand through reflection and dwindle during interaction. They tend to be more reserved and less outspoken in groups. Introverts generally enjoy time spent alone or with close friends, and find less reward in time spent with large groups of people.
Some of the typical solitary activities are reading, writing, using computers, hiking and fishing. The archetypal artist, writer, sculptor, engineer, composer, and inventor are all considered highly introverted.
Not to be confused as being shy - introverts prefer solitary activities over social ones, where as shy people (who may be extraverts at heart) avoid social encounters out of fear. Like extroversion, introversion is not a black and white measurement, and these people may share some of the same traits than extroverts., JapaneseA character originating from the island nation of Japan., lazyThe character`s favorite activity is doing nothing., loliLoli is a short form of the word Lolita, describing sexually precocious young girls. The related fetish for this is called Lolicon (Lolita Complex)., playing video gamesVideo games are electronic games played on a video screen, normally a television or a built-in screen when played on a handheld machine., twintailsTwintails are type of hairstyle where the hair is gathered into two "tails" on either side of the head.

female, bloodtype: O, adolescentAn adolescent (teenager) is 13 to 19 years old., boin complexA boin complex is an issue with one`s breast size where, instead of the more common issue where a female considers their breasts too small, the female in question feels insecure precisely because of their (greatly) above average breast size. Most commonly, that is related to the amount of male (and sometimes female) attention it brings. This is completely unrelated to and not to be confused with overweight or fat men who are not terribly fond of their manboobs., humanModern humans are the only extant members of the subtribe Hominina. Together with chimpanzees, gorillas, and orangutans, they are part of the family Hominidae. Terrestrial animals, humans are characterized by their erect posture and bipedal locomotion; high manual dexterity and heavy tool use compared to other animals; open-ended and complex language use compared to other animal communications; larger, more complex brains than other animals; and highly advanced and organized societies., JapaneseA character originating from the island nation of Japan., large breastsLarge breasts are breasts a fair notch larger than average, as found in some real life adolescent girls or fully grown women. They are bigger than medium breasts and smaller than huge breasts.
Note: This tag has many anime/character entries that need to be moved to the new medium and huge breasts tags. Please add the appropriate tag and remove this one from the corresponding anime/character afterwards., lethal chefThe character is hopelessly terrible at cooking, and any attempts he or she makes at making even the simplest dishes are spectacular failures., sewingSewing is the craft of fastening or attaching objects using stitches made with a needle and thread., studentA student or pupil is a learner, or someone who attends an educational institution.

female, bloodtype: B, athleticA person good at athletics or sports, who is not necessarily part of a professional/amateur sports team or club., cuteness fangA cuteness fang is a single prominent canine tooth that suggests a cat-like and energetic nature or a state of excitement. Cuteness fangs generally belong to the upper jaw and are more common on females. They tend to not exist in-universe and go unnoticed by characters. A cuteness fang should not be confused with fangs, which are multiple prominent canine teeth, as found in vampires or various animals, or a misaligned tooth, which is a facial misfeature with no relation to personality traits., humanModern humans are the only extant members of the subtribe Hominina. Together with chimpanzees, gorillas, and orangutans, they are part of the family Hominidae.

Often combined with a speed-eating technique that makes food seem to vanish spontaneously from the plate., shoulder-length hairShoulder-length hair is hair at shoulder length, within a few centimetres margin. This hair length is longer than what one would typically, though not always, see on most males. Short hair includes hair that goes no more than a centimetre or two beyond the chin; anything longer is shoulder-length. Typical male hair at the back of the head which reaches the shoulders does not count as shoulder-length hair; the individual hair strands are very short (0-4 cm), and therefore count as short hair., simple-mindedThis character exhibits a `special` sort of intelligence. Be it the inability to comprehend even the most simple of situations, or the lack of common sense found in even a preschooler, the character never ceases to amaze both the show`s cast and audience with their idiocy., studentA student or pupil is a learner, or someone who attends an educational institution. The may be understood to mean only those enrolled in some sort of educational institution, but, in its widest use, it applies to anyone who is learning, including mid-career adults who are taking vocational education or returning to university, or younger researchers or artists learning from a more experienced colleague and mentor.
