The song is "Electric Boy" from the South Korean girl group, Kara. They're singing in a mash-up of Japanese and English, though, not Korean. Well, never mind. The song's okay.

The dancing, though, is stiff, immobile and badly rendered. Even the clipping's bad. At one point, Nanako's legs go through each other. Boobs twang. Legs flicker into place, instead of moving. Meanwhile, the choreography is far worse than the original dancing from Kara, which is odd since these MMD videos often copy the original singers' dances. Nanako stays stiff and vertical almost throughout.

Nanako's design is distinctive, though, with that hairdo and those goggles. I bet she's a character from a video game, but I've no idea which one.

Do you like Disney's Frozen? Well, so do the makers of this. Anna's naked and manacled to the wall in Elsa's ice palace. Elsa has an ice cube and a glowing blue ball to insert into Anna's special place.

The CGI reproduction of the original characters is superb.

Iris Thea Eaderlindt is an elven princess. She's transferred to a human school as a goodwill ambassador... but there's no such thing as a male elf. The race is female-only and can only reproduce by crossbreeding with other species. (They can't have evolved like this, surely.) There were problems when they used online dating sites and got in trouble, so the government's set up an "assistance system".

Result: government-approved sex with her teacher. They're both a bit nervous initially.

It's gentle, good-natured nonsense. Everyone's nice. However there's little content beyond the sex scenes, while the genetic/evolutionary premise is absurd (albeit also ripe for fan theories).

A girl has sex, usually while biting a length of green bamboo because she's meant to be Nezuko from Demon Slayer: Kimetsu no Yaiba. She can ejaculate white fluid from her nipples. Any given clip might have up to five penises, some of which are as long as Nezuko's upper arm.

No plot or dialogue.

I watched the full version, obviously, not the cut-down TV episodes... but the latter don't seem enormously cut-down.

A gun-toting special policeman gets married to a novelist with low self-esteem. She keeps wondering what he saw in her. He also has a hot ex-girlfriend whom he might have married, but didn't.

As far as I can tell, this is an anthology series of vaguely romantic one-off stories. I like the idea. I just didn't think this episode was much good. The husband briefly puts his gun to the head of a colleague, although admittedly the guy was annoying. The story being told is a bit trite and not very interesting, although at least it chooses the nice ending rather than the unpleasant one I'd been worried about. The sex is... well, it's sex. Gee. The animation is mediocre.

Maybe the other episodes are better? It's possible, but they'd have to be significantly better to make me watch the rest of this.

It's adapted from a visual novel that also got three hentai OVAs in 2011-12. Don't ask me why they revived it, though, because everything significant here is so generic that you could forget that the characters have names.

The introduction's mildly interesting. Girls with enormous boobs wear bikinis at the beach... but they also appear to have superpowers. One girl has blue skin and purple hair. A talking dog decides to train them, which apparently means "beat them up". Next, we meet the Tsukimi sisters, Maria and Juugoya, who are fighting the Lunarian organisation.

None of this is relevant to the episode.

A boy called Katsuma has sex with Maria, who fondly remembers the time he raped her and took her virginity. Yes, she does. Yes, I did say "fondly". Apparently this felt good. Juugoya then has sex with Katsuma as well, even though he's her sister's boyfriend.
