Chapter 1-5 spoilers*

Arakawa under the bridge is a story about a high social status person who one day almost drowns. After having been saved by a girl, he promises to repay her by becoming her lover and so he suddenly starts living under a bridge with a group of very bizarre people, including his lover who claims she's from Venus.

Just with this premise, it kinda seems like shit but don't be fooled. It's a very good seinen manga with a lot of comedy (if you're into this type of random comedy). All the characters, behind their bizarre personalities and appearances have hidden backstories which you learn more about as the story goes on. Their sanctuary, their place of comfort is under the bridge. The whole mystery is developed really well and each person has their own unique past and demons, especially our MC's lover, but...

As the story goes on, about halfway through the story, it's as if the author had no clue what genre she wanted this manga to be. Whether she wanted this to be seinen, mystery, or just comedy or sci-fi. It ended up being a pretty big mess, which is a pretty shame since this manga could've been a really huge masterpiece
