Kodansha decided to make another printing of the January 2014 issue of Aria magazine, which launched Hikaru Suruga and Gan Sunaaku's Attack on Titan: No Regrets (Shingeki no Kyojin Gaiden: Kuinaki Sentaku) spinoff manga. The first printing of the issue was already five times greater than the magazine's usual print run, but after the second printing, the issue will now have 10 times more copies than usual.
The issue's first printing shipped on November 28, and the second printing will arrive in stores around December 16. According to the Japanese Magazine Publishers Association, Aria had a verified monthly circulation run of 13,667 from July to September, before the Attack on Titan spinoff launched.
The Attack on Titan: No Regrets manga focuses on Levi's past, including his first encounter with Commander Erwin and how he entered the Survey Corps. The manga is on the cover of both the January and February issue, which ships on December 28. Suruga is drawing the manga, and Sunaaku (Gargantia on the Verdurous Planet) from Nitroplus is in charge of the manga's scripts. Sunaaku is also penning Kuinaki Sentaku (No Regrets) visual novels that are shipping with the third and sixth Blu-ray Disc volumes of the Attack on Titan television anime series.
Hajime Isayama's original Attack on Titan manga has already inspired Saki Nakagawa's Attack on Titan: Junior High (Shingeki! Kyojin Chūgakkō) spinoff comedy manga series and is inspiring the Attack on Titan: Before the Fall manga by Satoshi Shiki that is based on Ryō Suzukaze's light novel series of the same name. Vertical is publishing the light novel series in North America.
Kodansha Comics is publishing Isayama's original Attack on Titan manga in North America, along with the Attack on Titan: No Regrets and Attack on Titan: Before the Fall manga. It is also publishing the Attack on Titan: Junior High manga and the Attack on Titan Guidebooks: INSIDE & OUTSIDE.
