Sekkachi Hakushaku to Jikan Dorobou (せっかち伯爵と時間どろぼう)
New manga by Koji Kumeta (Sayonara Zetsubou Sensei, Katte ni Kaizo, Joshiraku) serialized in Weekly Shonen Magazine (since 2013)!
More of the same style as Katte ni Kazo and Zetsubou Sensei, black humor and timely gags.
Raw chapters (12 onwards)
Volume 1 on Amazon
Volume 2 on Amazon
(I've ordered these 2. Amazon Japan ship books overseas.)
I saw chapters 1 and 2 (probably poorly) English translated.
