Nice combo from both Watanabe Akio and Shingo, like Soul Taker combined with Zetsubou Sensei.

Another anime from the duo( Akio and Shinbo )
Soultaker


and Uchu Senkan Yamamoto Yohko


Akio has been one of my favourite character designer, and i like the concept of shinbo works especially in zetsubou sensei. Will watch bakemonogatari once the hype is over.
