The November issue of Kodansha's Afternoon magazine is announcing on September 25 that Makoto Yukimura's Vinland Saga manga is getting a collaborative web anime with Vap's web anime Ponkotsu Quest . Vap will post the "Pon Kotsuland Saga" anime to YouTube on October 24. The magazine is also revealing a key visual for the crossover anime.

The announcement reads: "This is a limited one-episode collaborative-like 'thing' linking Vinland Saga and 'that'." The collaborative anime will star Keisuke Matsumoto as all the characters. The characters, whose names are a combination of Vinland Saga and Ponkotsu Quest characters, include:

Kakufinn (pictured left in above image holding a sword)

Imuladd (pictured above left on Kakufinn's head)

Tsuchikell (pictured center as teddy bear)

Kuronute (pictured below right with purple cloak)

Jijōkotsu (or auditory ossicles, the small bones of the ear. Pictured bottom right)

Ponkotsu Quest previously produced a collaborative short anime with the live-action Gatchaman film. The Ponkotsu Quest anime features the following characters (listed from left to right in below image): Kuronuma, Tsuchida, Kaku, Imura, and Mitsui.

Kodansha Comics, which publishes Yukimura's Vinland Saga manga in English, describes the manga as follows:

Thorfinn is son to one of the Vikings' greatest warriors, but when his father is killed in battle by the mercenary leader Askeladd, he swears to have his revenge. Thorfinn joins Askeladd's band in order to challenge him to a duel, and ends up caught in the middle of a war for the crown of England. From the creator of the classic Planetes manga comes this epic, highly-anticipated tale.

Yukimura launched the series in Weekly Shonen Magazine in 2005, but Kodansha moved the series to Afternoon later that year. Kodansha published the manga's 16th compiled volume in Japan in June.

Kodansha Comics released the sixth omnibus volume of the manga in English earlier this month, and it will release the seventh omnibus volume in December. Kodansha's license of the series only extends to the end of the seventh omnibus volume, so publication of further volumes will depend on sales of those two books.
