"Zerosen" is a Japanese old-fashioned high-school teacher comic. Author is Atusi Kase. This comic is in WEEKLY SHONEN MAGAZINE (Kodansha Ltd.).
Author Atusi Kase has a big hit comic "Chameleon" (カメレオン/Kamereon). He has not changed a bit since then. But that is fine with us. Sometimes it's wise to be not changed.
