Synopsis

Shougo Mikadono's father has just passed away, and now he must become the head of Mikadono Group, his father's company. After completing the training to take over, there is just one other stipulation he must adhere to: he will need to find a girl he loves at his new school and marry her by the time he graduates high school.

Shougo transfers to Miryuin Private Academy, and it seems like he has many girls to choose from, such as Konoe Suruma, the class representative as well as his first new friend; Miyabi Kannagi, a standoffish but kind girl; Rinka Kunitachi, the student council vice president; Mei Sagara, who runs a cafe and dresses like a witch; and Mana Tendou, the student council president. However, there is a complication: one of them is his long-lost half sister, and he has no idea which one, so how can he become romantically involved with any of them?

The ecchi scenes were marvellous, they were very erotic and some of them were coated with a touch of romanticism that made this anime stand out from the rest. Unfortunately all this build up gets thrown out of the window by the stereotypical "friend" or "event" that ruins the mood, nevertheless still a very enjoyable show.

The girls were really pretty and hot, I wish more anime studios weren't afraid of showing nudity as ten years ago... good old days.

Nakaimo gives you a good ending, no the best but still a good one, in my opinion you wont be disappointed considering how the plot developed ...

Mixed Feelings

Nakaimo is basically as average as you can get. So average in fact, I forgot everything about it, including having already seen it, and watched it again. I had this marked as completed on MAL for who-knows-how-long, but could recall literally nothing about it, including the answer to the titular question, “who’s the MC’s little sister?”

This is a PLOT heavy show that is heavy on actual plot. The premise is that the main character’s father has passed away, and he’s soon to become the head honcho at his dad’s company, so he’s going to attend a new, elite school, where he’ll become a refined, adult, ...

Recommendation: Harem garbage mixed with one of the worst mysteries you'll ever see. Don't waste your time. Some spoilers below.

Story: High school student Shogou is being set up as the heir to his father's company, but is given the instructions that he must find a wife by the end of the year to inherit it. Complicating this is the fact that he has a mysterious little sister who is attempting to be the woman he marries, so he tries to find out who the sister is before deciding on a wife because marrying his blood relative would create a scandal for the ... company. If this sounds like the setup for an unusually plot-heavy porn video, I can assure you that it's not written much better than one and has almost as many bare breasts. Though I won't spoil who, you do eventually get an answer to the question of "who is the sister?", but no answer to the question of "who does Shogou marry?". The 13th episode OVA strongly hints at a particular outcome to the latter question, but if you're looking for a scene where one character "wins", you won't find one here.

Inconclusive romance aside, the real sin here is the mystery of the sister, which sounds like an interesting twist on an otherwise generic harem series on paper. However, the mystery itself is so convoluted and poorly written that you should abandon any pretense of trying to solve the mystery yourself. There are multiple fakeouts where characters pretend to be the sister that make no sense at all unless you view them purely as red herrings, because they really don't have any reason to be pretending to be the sister except to fool the audience at home. It takes a bunch of pointless turns, new characters and evidence get introduced out of the blue as plot twists, rendering any attempt to figure out what's going to happen next an exercise in futility. After a few episodes of this, I was just checked out completely on the mystery and did not care who the real sister ended up being. If it was at least interesting, I could forgive some of the bad writing here, but it just ends up being confusing and boring.

Audio/Visual: Below average in both respects. The animation is stiff and generic, and the VA work is subpar for most of the characters. It feels like barely anyone that made this thing was putting in any effort. However, the girls are cute and they're topless pretty frequently, so if you're into that sort of thing, you'll probably enjoy that aspect of it at least.

Characters: All the harem tropes you know and loathe are here. Pervert MC that freaks out at a girl getting close to him but always manages to somehow fall on top of girls and grab their boobs in the process? Check. Tsundere that beats up the MC for seeing them in a compromising situation even though it was their fault? There are 2 of them actually. Girls having literal contests with each other for the MC's affections? Almost every episode. It's almost shocking how cookie-cutter the characters are. Of the main girls vying for Shogou's affections, Konoe is your typical childhood friend, Kannagi is your typical tsundere loli, and Kutunagi is your typical ice queen ojou-sama. There is nothing more to any of them than that. The only sort-of exception is that Konoe initially shows a bit of a playful prankster side that's kind of refreshing, but even that is quickly squashed flat and barely mentioned after a few episodes. Shogou himself is a total blank slate harem protagonist, although somehow even denser than usual and constantly causing problems by jumping to wrong conclusions in the sister mystery. The only characters that are even mildly entertaining are the peripheral members of the harem, the food-obsessed student council president Tendou, and witch-cosplaying senpai Sagara. Neither of them have any romantic chemistry with Shogou and seem to be almost reluctant harem members, showing only token interest in a relationship with him. Thankfully that frees them from the cringeworthy antics of the 3 main competitors and gives them space to just be goofy weirdos that provide the sole moments of entertainment to be found anywhere in this godforsaken series.
