This year's March issue of Kodansha's Monthly Shonen Sirius announced last Tuesday that it will debut six new manga series and a one-shot manga in the coming months. The new series include an original work by Ryukishi07 (Higurashi no Naku Koro ni) and manga adaptations of Concrete Revolutio, Odin's Sphere, and Chaos;Child . In addition, the magazine will debut Haruka Tomoyama's manga adaptation of Yūgo Aosaki's Undead Girl Madafarce novel and Yoshitsugu Ohara's Gata Girl manga. Gata Girl will debut in the May issue on March 26.

The magazine also promised a "big title" announcement in the next issue.

Ryukishi07's new project title is not yet determined. While Ryukishi07 is handling the original story, Yukari Higa (Shina Dark - Kuroki Tsuki no Ō to Sōheki no Tsuki no Himegimi, Mahō Senki Lyrical Nanoha Force) will draw the manga itself.

The Concrete Revolutio manga will focus on side-stories that did not appear in the anime. Mutsuki Nago is drawing the manga based on the story by Shou Aikawa and Studio Bones.

The first series premiered in Japan on October 4. Anime Consortium Japan co-produced the anime, and it streamed the anime on Daisuki as the anime airs in Japan. Funimation Entertainment also streamed the anime. The second season is slated for April.

Funimation describes the story:

What if superhumans were real? Even better, what if every fabled superhuman existed at the same time, in the same place? Titans from outer space, life forms from a mystical world, phantoms and goblins from ancient times, cyborgs created by scientists, relics that rose out of the ruins of ancient civilizations. In another Japan, it's not just a question of "what if"—it's a reality. Some of the superhumans choose to keep their identities a secret, while others bask in their superhuman fame. Jiro Hitoyoshi, member of the Superhuman Bureau, keeps track of their doings.

The Odin Sphere manga by Tomoyuki Hino will adapt Atlus and Vanillaware's 2D action RPG of the same name. The two companies first released the game for PlayStation 2 in 2007. Odin Sphere Leifthrasir , the HD recreation for for PlayStation 4, PlayStation 3, and PlayStation Vita, shipped in Japan in January and will ship in North America in 2016.

The game's story centers around a war between the kingdom of Ragnanival, led by the king Odin, and the realm of Ringford, led by the queen Elfaria. Their war has devastated the country of Valentine, of which only scattered ruins remain. The story is told from the perspective of five characters whose stories intertwine: Gwendolyn, valkyrie and younger daughter of Odin; Cornelius, prince of the neutral country of Titania; Mercedes, daughter of Elfaria and princess of Ringford; Oswald, a shadow knight and agent of Ringford; and Velvet, a survivor of Valentine's devastation.

The Chaos;Child manga will be an official spinoff centered on Mio Kunosato. The game's main scenario writer Eiji Umehara is also writing the spinoff, and Futsū Onshin ( Cannibal Junk ) is drawing the manga. The release date for the manga has not yet been revealed, but the magazine mentioned that it will precede the planned anime adaptation.

The original game is 5pb. and MAGES' fourth science-adventure title, after Chaos;HEAd, Steins;Gate, and Robotics;Notes. Chaos;Child first debuted on the Xbox One in 2014, followed by ports on PlayStation 4, PlayStation 3, and PlayStation Vita in Japan on June 25, 2015. A PC port is slated for this April 28.

In the psycho-suspense story, after a magnitude-7.8 earthquake hits Tokyo's Shibuya ward on November 6, 2009, a black fire spreads and causes mass panic on the day of the earthquake. The sudden disaster that becomes known as the "Shibuya Earthquake" kills 3,851 people and injures 30,927 more.

The game is set in a reconstructed Shibuya district in October 2015. A string of mysterious deaths occurs in Shibuya amidst the reconstruction. People begin to take notice as the strange events start on the same day that chaos broke out in Shibuya with a certain incident five years earlier. The events are called the "Return of the New Generation Madness."

Finally, Shonen Sirius announced that A Channel creator bb Kuroda will draw a one-shot manga called "Torikorooru" in the April issue on February 26 as part of the magazine's 10th anniversary celebration. The story will be about girls at a magic school.
