You can watch this on Hulu, CrunchyRoll, or HiDive.

Our hero wakes to a blaring alarm, only to discover that Miia, a Lamia, is curled up in his bed. She claims to be trying to warm up, but her coils are so tight our boy can barely breathe. Trying to get her to release him he grabs the tip of her tail.

This is effective in distracting her, because it's an erogenous zone. But I wouldn't say it gets her to loosen her grip.

She thinks her darling is frisky this morning. He passes out from lack of oxygen.

This is the cold open for the show.

The opening shows our boy having haremlike close encounters with a half dozen busty monster girls

Miia is here on an interspecies exchange program. Once the government stopped keeping the existence of demi-humans secret, the program was set up to help them integrate.

Our boy is Kimihito Kurusu, and he seems to have accidentally become a host family while his parents are away. Oops. Some kind of paperwork screwup, no doubt.

Smith, the interspecies coordinator drops by. She's noticed that Miia is desperately in love with him.

She's here to remind him about the Prohibited Matters: any injury to the guest is strictly forbidden... and under the current interpretation of the law, deflowering counts.

Not to mention, as the first Lamia in Japan, it would be a diplomatic incident!

So hands off, buster!

Miia doesn't care about the Prohibited Matters, and would fuck him right now.

Except in her excitement, she squoze him a little too hard and dislocated his shoulder. (Smith pops it back in.)

How about a date instead?

Sadly, most places are not Lamia-accessible yet.

This store says it's open for all species.

It's a lingerie shop. Shenanigans ensue.

Miia attracts attention on the street. Some inquisitive, some rude. Kurusu stops her from getting in a fight: the Prohibited Matters go both ways and if she injures someone she'll be deported.

In an attempt to escape unwanted attention, the pair get out of sight... by checking into a love hotel.

This is actually a chance for Miia to bemoan how scary she appears to humans.

Then the interspecies enforcement squad arrives to make sure they're not breaking any laws.

As they retreat, they are met with more mockery, and Miia gets mad. Kurusu determines that while the Prohibited Matters will get her in trouble if she overreacts, there's no law against _him_ punching that asshole in the face.

(I am not a lawyer, this is not legal advice.)

Miia asks him why he did it. Kurusu replies that he couldn't let someone be cruel to a girl like that.

Miia is overjoyed that he truly sees her as a girl despite the species difference and is DTF right now. Only Smith deciding to impose on them for dinner keeps them out of jail.

Papi the Harpy arrives. She's a birdbrain.

She kidnaps Kurusu because she's run away and knows she needs a chaperone. Shenanigans ensue.

When it becomes clear she'll be deported without a host, Kurusu volunteers to save her.

Miia is jealously protective of their relationship.

Centoria Shianus, the Centaur with a passion for justice, hunts down a purse snatcher that has been terrorizing the neighborhood. Of course, due to the Prohibited Matters, she can't actually fight him. She needs a patsy. Kurusu will do nicely.

Shenanigans ensue.

Turns out that riding a centaur is considered an extremely intimate act. And guess what happened?

Centoria decides that Kurusu is her destined master. She asks him to call her Cerea (her family and close friends do,) and moves in.

Smith lets drop some news: the interspecies exchange act may soon be revised to allow marriage. They just need a good test case.

The girls are sure they'd love to be a test case. But only one of them can be.

When a full moon sets their animal instincts loose, shenanigans ensue.

A slime girl appears. They name her Suu.

It's not clear how much mentality she actually has at first. She mostly seems to mimic others.

But when one of the neighborhood children is nearly hit by a car, she shows her own sort of heroism.

Meroune Lorelei (Mero), a mermaid, arrives.

I think we're blaming Smith for all the monster girls being in one house.

Miia is worried that Mero is a rival for Kurusu's love. (Shenanigans ensue.) But Mero is only interested in tragic love stories. She wants to lose.

Miia is molting and having trouble. Can Kurusu lend a hand? (Yes.)

Papi is going to lay an egg. A documentary filmmaker/pervert wants to film it, for science. (Or so he says.) He goes too far and gets thrown out on his ear.

We see him report to his boss: a spider-woman.
