A boy has such a huge penis that he finds it hard to masturbate. His big sister sneaks into the bathroom and takes a photo of him with the fleshlight he's just broken by being too well-endowed, then sends the image to all her friends and invites them to come around and see for themselves. Suddenly, our hapless hero is the subject of a Little Brother Cock Appreciation Party.

His sister gives him a hand job, then her friends join in.

"This anime is a work of fiction that attempts to depict the stories behind real world racehorses." This is true. It does. Apparently you can tell the gender of the original horse by whether this anime's horse-girl wears a ribbon/hat/other towards her right ear (stallion) or left ear (male).

That said, though, the episode basically just feels like More Anime Girls, but with a loving recreation of horse racing that feels exactly right except that the horses are schoolgirls. Running very, very fast. That was weird. The horse girls have an open day at school, so they show around some younger girls. A girl tells another girl that she's going to be strong and cool like her one day, then a few years later she is! There's running. There's a rubbish token male (the trainer) who I presume is the faceless protagonist character from the original mobile phone game.

Then, at the end, these horse-girls give an idol concert. (Incidentally, there are also live-action Uma Musume idol concerts. The idols wear horse ears.)

This isn't for me. It's a sports anime, combined with idols, combined with Empty Fluff With Anime Girls. Apparently it's better and meatier than Season 1, though.

It's less painful than I'd expected, actually. Girls wear swimsuits and play a song. That's it, really. Whoever edited this gets amazing mileage out of only a single drawing of each girl. Spin it, zoom in and out... anything except actual animation.

The video uses characters from Holo no Graffiti and Hololive Alternative, which are crimes against civilisation.

That was bizarre. Also dialogue-free, although there's a vocal element to the incidental music. A girl appears in a purple glowing light ball. There are a number of these, like flying Christmas tree decorations. She then runs through a town and makes purple magic disappear wherever she goes.

I've no idea what it is, but it's an experience. It would have been soothing had its music been gentler.

It's amusing. I enjoyed it. It's not strong enough to make me watch the rest of the series or suggest that anyone else go looking for it, mind you, with a plot that's just: (a) "meet random weirdos and solve their riddles", interspersed with (b) "nocturnal hentai scenes with Bunny-Ears Girl". Nonetheless, it had enough of a sense of fun and eccentricity to be a laugh.

The episode starts with an ordinary bloke walking down the street... and suddenly being teleported to another world! Orcs are threatening a Bunny-Ears Girl! Can our useless-looking isekai hero rescue her, despite having no combat skills whatsoever? Surprisingly, the answer is "yes". Challenges in this fantasy world are conducted with riddles. "Which animal doesn't belong in the Chinese zodiac? 1. fox, 2. boar, 3. dog, 4. horse."

The male protagonist is a joke in himself. He "talks" in question marks in word balloons, or in nods. Bunny-Ears Girl gains the kind of mind-reading conversation skills I last saw when watching Lassie. "You're going to masturbate so I should show you my knickers?"

There's a bargain-basement anime version of Bananaman. There's a dodgy ghost. Bunny-Ears Girl gets enthusiastic enough about her nocturnal responsibilities to start getting pouty-faced on meeting other girls. It's silly, of course, but there's nothing particularly problematic about this first episode and you could do much worse.
