High school student Alice Sakaguchi encounters an obnoxious seven-year-old boy named Rin Kobayashi, who takes a shining to her. At the insistence of her family, Alice grudgingly becomes Rin's babysitter. Oddly, sparks start flying between them.

While on one outing, Rin and Alice wind up having coffee with two of her classmates, Jinpachi Ogura and Issei Nishikiori. Alice learns that they too have recurring dreams about the doings of a group of seven humanoid alien scientists who observe Earth from their moon station, having been marooned there after an interstellar war.

Alice, Jinpachi, and Issei successfully seek out two others, Daisuke Dobashi and Sakura Kokushou, who have had the same alien dreams. Daisuke and Sakura explain to them that they are all the reincarnations of the very good-looking alien scientists, who, though they were very good-looking, died tragically of a deadly virus contracted while observing Earth from the moon.

The reincarnations are as follows:

Alice is Mokuren, who listens to plants and animals, who loves Shion, who is nonetheless the love interest of Gyokuran and Dr. Shukaido as well, who is now a hapless brunette instead of a hapless blonde.

Jinpachi is Gyokuran, who loves Mokuren, who has ESP but can't control it unless he wears earrings.

Issei is Enju, who was once a tele-pathic woman in love with Gyokuran, who is now a pathetic man in love with Jinpachi.

Sakura is Shusuran, who constantly chews out Issei/Enju for being so tele-pathetic.

Daisuke is Hiragi, who is the team leader and linguist, who does nothing other than explain tangled background information to the audience.

Two members of the team, Dr. Shukaido and Shion, are still missing, but it should be noted that at this point Rin is flying around without the aid of a plane.

Rin is terrorizing a rich kid named Takashi with the aim of gaining control of the Tokyo Tower, whose current renovations are under the direction of Takashi's father.

Rin, through psychological melees, bullies new architectural plans for the renovation of Tokyo Tower into the hands of Tamura, Takashi's body guard.

Rin is Shion, who was the moon station's bad-boy engineer, who once enjoyed reciprocated love with Mokuren.

Haruhiko, Takashi's faithful friend, is Dr. Shukaido, who was painfully jealous.

Both were members of the alien scientist team that dropped dead one by one from an insidious virus as Dr. Shukaido worked frantically to create a vaccine. By the time he succeeded, only he Shion, and Mokuren were left, and there was only enough vaccine to inoculate one of them. Dr. Shukaido gave Mokuren a placebo and the real vaccine to Shion, dooming Shion to nine lonely years on the moon station.

Finally, Shion succumbed to the virus and was reborn as Rin. Rin/Shion wants revenge on Haruhiko/Shukaido, the love of Alice/Mokuren, and to blow up the moon station using a modified Tokyo Tower.

Alice has ceased to believe that she is Mokuren, despite the fact that animals and plants talk to her. She begins attending school choir practices instead of alien moon people club meetings.

Issei/Enju confesses his love for Jinpachi/Gyokuran, kisses him, is spurned, and cries about it to Sakura/Shusuran.

Issei/Enju and Sakura/Shusuran rescue Haruhiko/Shukaido when he tries to kill himself.

Tamura figures out that Rin/Shion and Haruhiko/Shukaido are aliens with ESP.

Tamura allies a human telepath, Mikuro, with him in his defense of Haruhiko/Shukaido against Rin/Shion. A massive psychic battle ensues. Rocks fly, lightning crashes, fire blazes, but no one gets croaked.

From his post-battle hospital bed, Rin/Shion has a trippy flashback to his alien youth that clarifies his psychological development.

The battle won, Tokyo Tower remains unmolested. Alice/Mokuren, Jinpachi/Gyokuran, Issei/Enju, Sakura/Shusuran, Daisuke/Hiragi, Haruhiko/Shukaido and Rin/Shion are all still alive, are all still single, and have given no clear indications of their future plans, other than a vague, tragic allusion to Rin and Alice going to the beach together sometime.

This OVA opens with an intriguing premise and the promise of interesting character development. But none of this comes to fruition. The eventual maturity of the characters, and even the conclusion of the story itself, simply never occurs, leaving the irritating feeling that six and a half hours of concentration on the exploits of sixteen major character have been completely wasted. But it is not only disgust at a lack of an ending that triggers this unforgiving thumbs down. None of these characters turns out to be very interesting, and many of them are down right annoying.

Stripped of the characters that are intended to drive it, the narrative is as moist and flimsy as one of Issei/Enju's tissues. A reasonable viewer will, assuredly, overlook a number of flaws if the crux of a story is gripping, but "Please Save My Earth" asks its audience to make too many leaps of faith and contains too many inconsistencies to be credible. And without even one strong chord binding it together, director Kazuo Yamazaki breeches the integrity of the concept.

Questions abound about:

WHY...

... did the aliens stay on the moon rather than come down to earth considering their own civilization had been blown to smithereens and they had no place else to go?

... were they observing Earth in the first place?

... didn't the moon base's advanced alien ventilation system filter out the virus, and for that matter, how did it invade the moon base to begin with?

... once he was vaccinated, didn't Rin/Shion's repeated exposure to the virus maintain his immunity to it?

... does Haruhiko/Shukaido try to kill himself?

... does Haruhiko/Shukaido try to kill himself by jumping from a safe height into a slow moving river, unencumbered by cement galoshes or even bulky clothing?

... was this series called "Please Save My Earth?" There seemed to be a thread of conservationism running through the plot indicating that if we don't change our wicked ways we are doomed to interstellar war just like these fictitious aliens, but it was never made clear exactly how that was supposed to happen. What was the point of that?

... does Rin/Shion want to blow up the moon base? How will that save the Earth?

How coincidental that ...

... the last three aliens to survive on the space station were the three in the most feverish love triangle.

... they were all reborn in Japan, three of them attending the same school.

How absolutely incredulous is it that ...

... Dr. Shukaido could only come up with one vaccine.

... seven random scientists could all be so good looking.

... men weep so frequently, so suicidally, over nothing.

... Alice/Mokuren, with her room-temperature cream of wheat personality, could be the object of so much abject affection.

But maybe this is all unfair. "Please Save My Earth" is beloved of many, and it can be enchanting, though it is bereft of even one solid virtue. "Earth's" body of useless tears and mucus squishes through the iron frame of its premise, leaving the residual feeling that the only reason people enjoy this anime is that they'll buy into any half-assed story which includes pretty boys and a love triangle.

Love it? Hate it? Buy it.
