So I just started and got caught up on this really bizarre manga called Arachnid. It's a bit hard to read at first, with a strangely emptying-depressing atmosphere and unnecessary fan service in the beginning (with a few NSFW panels, these being the hardest bits. The beginning in general has a heavy creepy rapey guys sort of theme, kind of like stuff you'd find in post-apocalyptic stuff), but the coolness of the MC's weapon should keep you reading for a bit. Also, the MC is named Alice and uses a jackknife thing that can detach its blade. The thing is that this manga has a HUGE bug motif/theme going on, the MC's being a spider. Her knife-thing shoots out the blade end, to which it remains attached via an infinite spool of spider thread. If you haven't guessed, Alice's bug motif is a spider.... Arachnid, title drop. So it's interesting, especially for us, since she kind of looks like our resident rainbow puppeteer and even uses the threads like marionette strings.
So why should you keep reading?
The premise becomes more and more ridiculous, especially past chapter 18 or so when the first arc kicks in. What starts as a sort of theme just goes off the far end into sheer ludicrousness, into the realm of extremes. In a Kill la Kill sort of way. There's also a character in it who's the biggest Kamen Rider chuuni I've seen in manga/anime yet. And a character who has a COCKROACH theme... and she's a girl. In fact, the characters in general kind of have a Touhou-esque-quasi-expy-ness to them.
If you can get past the beginning creepy NSFW bits, then you get to experience your suspension of disbelief-shoulders getting dislocated. Then you set them back in and accept, only for the next chapter to re-dislocate them again anyway with new ridiculousness.
TLDR; A random story about Wikipediac anthromorphic bugs (mostly girls +2 chuuni Kamen Rider nerds) thrown into a pit against each other.
Also, I recommend Mangahere.co because of its tsukkomi system where you get to post comments on the manga pages; kind of like a static niconico, except instead of groping your way through the site trying to register an account in Japanese, you just need to type in a simple Captcha key. Comments are pretty golden. A few shitposts now and then, but its the internet full of humans, what do you expect.
edit:
Ah, there's another one I forgot about: Cahe [sic] Detective Club. The title is based on the MC's inability to properly pronounce 'Cafe' 「カフェ」, becoming 'Cahe'「カヘ」. It's similar to the likes of multi-story segment chapters like Azumanga Daiou, in that each chapter is separated into a slice-of-life-y comedy shorts. But with a little more emphasis on linear progression of events. I avoid 'story', because of no plot, like many in the genre. I read it just for some light-hearted comedy and fun. It's nothing super exciting or amazing, but it features references to stuff I like (more on that later) and even a cute, rather original (compared to typical manga/anime), romance between two main characters.
The premise is basically that the school only has space for one more club, and 5 freshman girls each have different ideas. They decide to just create one giant detective-gaming-tokusatsu-dress up-cooking cafe. If you couldn't deduce already, those were the primary defining traits of each of the main cast girls. I like mysteries, games, Kamen Rider, maid outfits, food, and the cafe is a fairly amusing Local Hangout spot, so all is well with me. Obviously this is where the references come from, though most of the comedy comes from character quirks (which is granted, given the genre once again). Interactions between the characters drive the comedy and is actually pretty fun to follow along with. Especially because of how much of a little troll the MC is.
It's actually kind of therapeutic in its light-heartedness. The completely ineffectual fanservice is pretty parodical. I do recommend.
