Synopsis
At 22, college student Tsuyoshi's biggest commitment is to his canned chu-hai collection. That changes when his aunt Yui Koriyama shows up at his apartment, supposedly sent by his mom to make sure he's eating real food. Yui's a married office worker with a sharp tongue and zero respect for personal boundaries, and once the drinks start flowing, things get way more complicated than a family check-in should ever be. One drunk evening later, Tsuyoshi's quiet apartment life is over, and he keeps finding himself in increasingly intimate situations with Yui and other married women who drift into his orbit. This is an 8-episode ONA adapted from a seinen manga by studio Raiose, and the structure is what makes it interesting: it's omnibus-style, so each woman gets her own arc with her own circumstances and personality. The character designs lean toward realistic body types rather than the usual exaggerated proportions, which gives the whole thing a grounded feel even when the scenarios are anything but. There's genuine awkward humor threaded through the intimacy, not just wall-to-wall fan service with no personality. If you've watched stuff like Taboo Charming Mother or Oni Chichi and wanted something with a bit more emotional texture and less melodrama, this hits a different note. It's adult content that actually bothers to make its characters feel like people with messy lives and questionable decisions, which honestly makes it more compelling than most entries in the genre.

How do I read the mangas?
You see her acting all strict and then the alcohol hits and she becomes a totally different person by the end of the night
I think I need a drink after watching what Tsuyoshi did with his aunt because those visuals were way more intense than I thought they would be
It is wild how this show just jumps straight into it, especially since Yui is technically family even if they are not related by blood.
Yui really just invited herself in and started a drinking game that ended with them in bed
My brain was not ready for this because I expected a normal romcom but then the chuhai came out and Yui just went for it
seeing her go from a strict aunt to that version of herself after a few drinks was the best thing, and the soundtrack during that part was perfect
you really have to wonder how he is going to face his mom after what he did with her sister but that ending was intense
that scene where they are drinking and the atmosphere changes so fast was the perfect setup and yui is basically the ultimate aunt trope
I can't believe how fast they jumped into the main hook of the story because usually these shows drag it out for ages, but Yui and Tsuyoshi were already at it by the halfway mark. It felt a bit rushed, but the chuhai lips metaphor was actually a cool way to frame their first intimate night together, and it set the mood well
it was wild how they just showed everything without holding back and yui looks even better in motion than in the art
i was actually stunned when tsuyoshi finally gave in because i thought he would struggle more but he just went for it
i did not think they would go that far in the first episode but yui is definitely something else and that whole drunk scene was wild
the way she just forced her way into his room and then things escalated because of a drink was a lot to take in at once
Yui is exactly what the posters promised and the animation during the actual encounter was surprisingly high quality for this kind of show
tsuyoshi actually going for his aunt after all those years was crazy and the chuhai flavor thing was a weird touch but it worked
you really should not watch this on a bus or anywhere with people nearby because that ending with the aunt is way too much for a normal tv show
that chuhai challenge scene in the apartment had my head spinning because Yui is supposed to be his aunt and she just went for it without even hesitating once
it really feels like watching a hentai with a slightly bigger budget, especially when Yui starts acting like that after a few cans of chuhai and her husband is just nowhere to be found
going from a strict aunt lecturing you about your messy room to doing that on the floor is a massive jump and the alcohol excuse is doing a lot of heavy lifting here
