The March issue of Shueisha's Saikyo Jump magazine will announce on Friday that Izumi Todo (a collective pseudonym for the Toei Animation staff) and artist Naoya Sugita's Majin Bone manga, as well as Capcom and Yasuki Tanaka's Gaist Crusher manga, will both end in the magazine's May issue, which will ship in Japan on April 3.

Sugita launched the Majin Bone manga in Shueisha's Saikyo Jump magazine in January 2014. The series adapts Bandai and Toei Animation's television anime series of the same name. Yuusuke Murata (Eyeshield 21, One-Punch Man) provided the original character designs for the anime. The anime series premiered in April, and Crunchyroll streamed the series as it aired.

The anime's story follows ordinary high school students Shōgo Ryūjin, Tyrone, Antonio, and Luke, who are known as the White Bone warriors. With their special Bone Cards they defend Earth from the evil Dark Bone, who has come from the darkness to destroy their world. However, the true identity of the "enemy" is still uncertain.

Shueisha published the first compiled volume of the Majin Bone manga in July.

The Gaist Crusher manga is part of a larger cross-media production that involves a 2014 3DS action game, a 2014 television anime series, and more. In the story, Gaimetal, a metal ore with high amounts of pure energy, was discovered 50,000 meters (160,000 feet) underground in 2047, and mining began all around the world. However, Gaist — metallic lifeforms whose bodies are entirely encrusted with Gaimetal — emerged in 2055 and began attacking people. In 2064, Rekka, Hayato, Kurama, and Siren are among those who suit up in Gaist Gear and battle over 100 varieties of Gaist creatures.

Studio Pierrot produced both the in-game cutscenes for Gaist Crusher and the TV anime series, which began airing in 2013. Tanaka launched the manga in both Shueisha's Saikyo Jump and V Jump magazines in 2013. Shueisha released the manga's fourth compiled volume in September.
