Compilation of short stories:

Hotel: Since 2079 (2006)
It is the year 2272 A.D.

A computer continues to live on in order to complete a mission in a world where all life, including Mankind, has gone extinct. This is a record of those 27 million years of its heroic struggle.

Present (2006)
Hanako suffers from a terrible disease. After awakening from a deep slumber, Hanako has only three days to live.

Subete wa Maguro no Tame datta (It Was All for the Tuna) (2008)
Tuna have become extinct and Jun Shiozaki will do everything possible and imaginable to bring them back.

Set in modern-day Japan, our main character Noriko finds out that she is pregnant with her lover Matsumura’s baby. He, however, is an important doctor with a family and everything already. Noriko wants to have the baby, but Matsumura says that it’s actually a rapidly growing cancer and that they have to remove it immediately. It might also be neither of these things…

A "Diadem" is a word for 'crown' that has its root in Greek. "Stephanos", which appeared in "Mandala" 01, was also a 'crown'. It seems that we could consider this the second work in a continuing series of shorts that should perhaps be called a "Crown series".

Some of you people are too serious. Propaganda my ass. Global warming wasn't the main message in the story. yblees summed it up. Imo, for a one shot, it drew emotion, it provoked thought, it delivered. Nuff said.

Reading the earlier comments about the global warming message - I get the feeling those readers may have completely missed the story of the "person" who against all odds, over an unimaginable period of time, stayed unwaveringly true to the memory of it's most important people in "his" life.
I rarely give 10 ratings, but this definitely deserves it.

I wasn't expecting much from this oneshot but when i started reading it i felt that the author made a great story. I recommend that fans of sci-fi manga read it.

The story could fit All Gore><

I agree with the commenters below... It does seem like something All Gore will talk about and such. And also, that's it's clearly a statement...

So, regarding the manga itself..
Art- not so good, avrage, maybe less.
The story, no, the idea was good, and some of the written was good.
But it was carried out quite poorly, I must say.
Some strange comedic moments, and stuff like that...

About the ending
Spoiler (highlight to view)
It said that the computer saved the spesimine of a human DNA. I think it was better off without any human DNA left, because humans do only destruction, and reviving them is just ... Shouldn't be done...

Global Warming vs. Life Eternal.   
Rating: 5.0 / 10.0

At first glance, I almost would've guessed it was Al Gore's work. "You pulled the trigger, killing the earth with your GW!"

But. At the end I had another thought about this in mind. Maybe it was unintentional; maybe GW was the only thing that he wanted to come across.

Life is eternal. The Circle of Life. We created a machine, became extinct, and then that same machine created/restored us. Man, who had destroyed the world, would create the very thing that would restore it.

It's how I see it. I prefer Poetry over Propaganda. ... Then again, I don't like poetry either.

-edit- Christ, I don't remember this one-shot at all, and my own review didn't help at all...

Purely Propaganda   
Rating: 2.0 / 10.0

It goes without saying that this is a political piece. While I in general dislike reading pieces that are overtly political -- rather than stories that integrate political themes into the backdrop -- I am generally willing to overlook that so long as the author can provide us with either an entertaining story or a deeply thought provoking outlook.

Hotel provides us with neither.

The story is just too short and it's like reading from a diary where entries come only on blue moons and are lacking detail to begin with. What little we see of the characters actually does make them seem interesting, but they are badly underdeveloped for the sake of emphasizing the political nature of the story. If anything, I think making the characters more dear to us would have helped emphasize the political message AND make it a better read.

As far as the story, Boichi's (the author) message is simply "global warming will cause a huge and unavoidable disaster." That's it. There's no scientific discussion, no thought provoking insight into the nature of man, and no proposed solution other than self-annihiliation for the sake of the planet.

Compared to authors like Masamune Shirow (author of Appleseed and Ghost in the Shell) who engage the reader with deep philosophics, the difference is clear.

My rating: 2/10

This story takes a highly speculative theory (note: global warming is not speculative; a sudden and irreversible catastrophic climate change is) and presents it as a fact to show us that we are dooming ourselves, but even that message is unclear given the very last scene, which indicates that technology might save us as well. In short, this story is purely propaganda.

The redeeming aspects are the characters, who I desperately wanted to see more of, and the art, which ranks among the best I've ever seen in any manga ever. But drawing good pictures does not make good manga.

If you want to read an environmentally driven story, you're much better off checking out Nausicaa or Blue Gender.

while reading this, I was listening Peter Gabriel's The Drop. mixed together, it had a great impact on me. I love the idea and artwork. short but full of meanings.

This one-shot is brilliant. The artwork is beautiful, the story tight and compelling. It also carries an important message - and is truly touching, as well. Sci-fi at its best, as well as manga at its best. A brilliant work.
