Due to Yū Sasuga's Health
This year's 14th issue of Shueisha's Young Jump magazine is revealing on Thursday that Yū Sasuga and Kenichi Tachibana are putting their Terraformars manga on hiatus on March 9 due to Sasuga's health issues. (This year's 15th issue of Young Jump ships on March 9th.) The magazine's editing staff added that the two creators are aiming to resume the manga this fall.
In addition, the manga's 21st compiled book volume has been delayed indefinitely from its planned May 19th release. Pre-orders for the limited edition of the volume, which was slated to include an original anime DVD, have been halted, and all previous pre-orders are being cancelled. The magazine, as well as its website and Twitter account, will announce an exact date for the manga's return, and for pre-orders of volume 21, at a later date.
Sasuga and Tachibana launched the original Terraformars manga in 2011. Shueisha shipped the manga's 20th volume on February 17th. Viz Media is releasing the manga in North America, and shipped the manga's 14th volume in September.
The first 13-episode television anime series adapting the Annex 1 arc of the manga premiered in September 2014, while the Terraformars Revenge sequel TV anime premiered last April. Crunchyroll streamed both series as they aired in Japan. The manga also inspired a two-episode OVA series in 2014 that adapted the manga's Bugs 2 arc. The episodes shipped with the manga's 10th and 11th volumes.
The manga also inspired a live-action film that opened in Japan last April.
