The anime of Id Invaded had one of the most interesting concepts I've seen in anime (though I'm definitely biased because sci-fi, detective, subconscience are some of my favorite themes) Anyway, even though I really enjoyed the series, the ending left me a bit unsatisfied, like they could continue the story even more. So I found out that there's a manga version ( and after waiting for some time to be it fully translated I finally got to read it today yay) The manga is a sequel so you're supposed to watch the show first, so if you haven't watched it, stop reading, a give it achance (if you have time and want to read something fresh, because I feel like this genre is very rare nowadays)

Ok, so for the people who have watched the series,
Does this manga answer your questions and give a proper ending to this story?
Nah
I really hope they do announce a sequel
Was it good?
Yep, the case was interesting. Though I feel like it raised more questions than it answered.

The ID well was very thrilling, you could constantly feel the danger. Personally, I've always loved the investigations in Id well more than the ones in reality.
There were some beautiful drawn panels with Kaeru chan that left an impression on me.

Overall it was a nice short read (it included also a theme that I really like but I don't want to spoil it)
It's not anything mindblowing or breathtaking, you can definitely skip it if you want.
But if you really liked the show, like I did, give it a shot. Or maybe you can add it to your plan to read and after some time has passed, you can read it just to remind yourself of the series' atmosphere.
That's all folks, stay safe :)
