From Adachi's Universe:
We start with our main protagonist, Shichimi, bidding farewell as he readies for his journey into Edo (on our Earth, Edo was the old name of Tokyo before it became the capital of Japan). His mother has just died, only leaving him a walnut and a request for him to go to his half-siblings. Shichimi bids farewell to a sternly old man, who is a firefighter. We can tell this from the symbol on his cloak. This symbol is also on Shichimi's cloak. Upon reaching the town of Edo, Shichimi meets a mysterious man, who ridicules the peace of the world as an illusion.

[From Entropy]:

This is a story about aliens. Yes, aliens. Choi Sera houses displaced aliens in her home, where they all pretend to be UFO fanatics in order to explain their eccentricities. Sera’s job is to teach these aliens how to live in human society—not that difficult on the surface, as they ostensibly look like humans (except for the three fingers on each hand thing). They look normal, and they can communicate with earthlings via a translator that looks like a hearing aid, but can they act normal?

The answer to that is a resounding no. Watch as Sera tries to school the emotionless twins, Seunghyun and Seungmin (really clones) on dating (with disasterous results), tries to keep Hyunwoo out of trouble, and keep them all from being taken away by the UN alien hunter who’s on to them. And what happens when a translator breaks?! Find out in Safe Again Today!

Prince Kanmen is very persistent; and Sumire who is caught in between various fiancées, older brothers, younger brothers, obsessive SM handmaidens and pop stars, he may just end up marrying Prince Kanmen out of sheer exhaustion!

Nanami Sekai gets scammed out of every penny he has, left only with a pair of boxers and a 3,000,000 yen debt. He then meets a girl, Ritori, who offers him a deal that seems too good to be true: she will take care of his debt if he will be her captain and help her with her job.

[Note]
It seems that this manga has been discontinued because the author became incapacitated during serialization and was not able to keep 2 series running.

The story revolves around Taiga, who doesn't have memories from further back than two years ago when his parents died in an accident. He lives with his sister, Tsubame, whom he finds out is from outer space with the job of protecting him as he possesses the Origin Heart.

Our hero Vash the Stampede disappeared for two years after blasting a crater onto the moon above the desert planet he saved from annihilation.

Note: Nightow changed publishers to Shonen Gahosha and the series continued to be serialized in Young King Ours magazine. Due to the original publisher retaining the name Trigun, Nightow had to change the title to Trigun Maximum, which isn´t a sequel but a new name for the rest of the series. The first 3 volumes were published under the title 'Trigun' and the entire series compiled into 14 books as 'Trigun Maximum' (the numbering was also restarted when the title changed).
