MCLAREN VALE, Australia — The hugely popular comic book series "Kami no Shizuku" ("Drops of God") that follows the international adventures of two brothers in pursuit of the perfect wine was largely unknown in Australia.

That was until one of the country's oldest wineries got a mention.

The "manga," approaching its fifth year of publication, is penned by the brother and sister team Shin and Yuko Kibayashi, who write under the pseudonym Tadashi Agi.
