Sunohara-sou no Kanrinin-san

If you’re into the whole shota/Onee-san dynamic, Miss Caretaker of Sunohara-sou might be worth checking out. It’s a pretty chill slice-of-life rom-com about Aki Shiina, a shy boy who moves to Tokyo and ends up living in a dorm run by Ayaka Sunohara, this super sweet and motherly older woman who basically spoils him rotten. Aki obviously develops a crush on her, and that dynamic is the heart of the show.

The characters are what you’d expect from this kind of anime. Ayaka is the busty, caring, sisterly Onee-san who dotes on Aki like he’s her little brother (or more). Then there’s Nana, her younger, gyaru-like ... sister who’s fun but not as over-the-top. You’ve also got Yuzu, the small, serious loli type; Yuri, the pervy yuri girl; and Sumire, who’s into feminine guys and takes a liking to Aki because of his cute feminine looks. Oh, and Nana’s friends are total shotacons but don’t really flirt with Aki—they’re more into teasing...a lot.

The story is really basic, though. Each episode is like its own little sketch, usually focused on setting up funny or awkward moments. There’s a lot of humor about boob sizes (classic) and Aki trying to impress Ayaka with mixed results. There’s not much character development in the anime, so if you’re hoping for big moments or serious romance, this might feel slow. It’s more cute and playful than anything too serious or uncomfortable, especially with Aki crushing on Ayaka.

The art is fine. It’s not the most detailed or amazing, but it fits the vibe—soft and cozy. Ayaka and Nana are definitely the standout designs (for obvious reasons), and overall, it doesn’t feel cheap. The animation does the job.

When it comes to fanservice, it’s what I’d call “light ecchi.” There are plenty of suggestive moments, mostly involving Ayaka being, well, *very* close to Aki, but it doesn’t go too far. It’s more about teasing and playful vibes, so don’t expect anything over-the-top. Nana brings some fun energy with her teasing, too.

Overall, it’s a decent, laid-back show. Nothing groundbreaking, but if you like the idea of an Onee-san spoiling a younger guy or just want a slice-of-life with some light ecchi moments, it’s worth a watch. It’s fun but doesn’t do anything super special.

Do you like waifus? That's pretty much the only appeal this show has. It's not overly ecchi and the characters are all lovable and well-designed, but that's about where my enjoyment ends. There are a few good jokes sprinkled here and there, but many of them have virtually no punchline and might as well end with an "I can't stand it!" from Peanuts, as if it's the character's confused frustration over a bad punchline that is supposed to be funny.

I don't know how this is supposed to be a coming-of-age story for the barely-a-teen MC Aka when almost half of the jokes are him getting ... kind of molested by his voluptuous house maid Ayaka or her younger sister Nana. But if you like gorgeous and idealistic waifus, they've got the physical appeal and moe personalities that will make a sad weeb's heart go doki-doki. It's hard to see what events throughout the school year might have helped him develop into a more mature young man when so much of the series is just goofy hijinks or characters comparing their bust sizes.

Did I mention these beautiful ladies have MASSIVE knockers? Because they sure are going to remind you of that fact quite a bit. Although the first few punchlines around that fact made me genuinely chuckle a little bit. BUT YES! We know you have big boobs and Aka's hormones are finally surging as a young adolescent and he's very embarrassed! Ha ha! So funny!

The side characters play their roles within each story, as well, offering emotional support when needed and providing plenty of genuinely hysterical comedy (and fan service, because duh).

So I can recommend this anime to anyone who just wants to shut his brain off and maybe claim one of these girls as your waifu, because it isn't incredibly engaging story-wise despite having some good highs.

Ah, and Aka eventually wakes up with his curvy older sister crouching over him in her underwear. Sooooo . . . what crowd did they make this show for? O_O

Okay so.... I definitely watched this that's all I can say.
I wanted to find an ecchi anime to watch for fun and didn't even realize it included shota based on the cover and I also have this policy that I don't drop animes since I don't want to.
Like other reviewers have said: if you like big breasted waifus.. that's about what this anime has to offer. Most of the episodes didn't have many interesting things happening, there wasn't really a storyline and A LOT pf the themes kept repeating (like Ayaka wearing a school uniform). This whole anime is basically all of the older women ... molesting this middle school boy and genuinely nothing else.
The art and animation was okay, that's about where it ends. You couldn't really get attached to the characters since most of them were dislikeable.
I do not recommend this for the average viewer however if you like a bland story with little ecchi and a shota protagonist.. I guess this is for you.
Best part about this was that it's only 12 episodes long.
