But one day, his already bad luck takes a sudden turn for the worse.

[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!

Quoted from 4dawgz (the scanlator)-
"So there's a magazine called Gelatin where various manga artists are given some coloring crayons and then told to draw whatever they want in full color. The plot for this is about a guy and a girl who go on a mission to retrieve a pair of shorts from an island... aaaaand that's it. All you'll find is a nice slice-of-life story and lovely colored pages."

In a deserted place, wish upon coins, then laugh loudly three times, your wish will come true... The carefree and outgoing Eu Hee secretly likes a girl; however the person she likes is another senpai. If this isn't ridiculous enough Eu Hee decided to help her confess to her crush! A sweet and light-hearted tale, the Mi Sa-Lyn's first oneshot after her Debut.

She's the most popular girl in school, but what all the guys don't know about Akari is that she's actually a yaoi-crazed doujinshi artist... and her subjects look an awful lot like some boys from school. from snoopycool

4-koma manga

One day, an un-named ordinary high school girl (her name is left to your imagination), meets Cheko, a maid sent forth from a village of maids. Cheko the maid can melt, fly, remove her head and violate physics.

Surrounding the "ordinary high school girl" and her strange little maid are yuki-onna's who hate cold, a cute squid that can speak, moe yankees, tsundere maid assasins, ecchi lesbian teachers, trap yuki-otoko's, gentlemanly yakuza and many more.

She calls herself Sexy Voice. To most of the world, she's just Hayashi Niko, an ordinary schoolgirl - but when time permits, she lives a double life as a hired investigator/spy. To help her, she has recruited the rather unlikely assistant she calls Robo, a geeky lump of a man who doesn't really know why he feels the need to do everything she tells him to. He just does it. Together, the odd team solve a number of cases for Sexy Voice's employer, an aging gangster.
