Baccano!

Both of them have large cast of characters. Also, the full story is divided in different pieces through each episode...like a puzzle. And both have suspense, mystery, and really gory scenes.

Mononoke

If you liked the story about a man wandering around from place to place, "saving" people from supernatural creatures, then Mononoke is for you. But Mononoke has bizarre scenes, really artistic detalis, and also...it's a dark version of Mushishi.

Abenobashi Mahou☆Shoutengai
|
If you like twisted plots, and funny scenes all the time. You'll like this series. It's made by Gainax too, and have many references to many pop cultural manga & anime stuff. It's a weird comedy, but you'll have a good time with Abenobashi.

Ergo Proxy

Many questions about life. Many things that you can explain with words...but sometimes you can't just explain in a normal way. Life or death? Good or evil? What is the meaning about the most small things in the excistence. If you like weird stuff...you will love Ergo Proxy.
