12 Beast (Japanese: トゥエルヴビースト, Hepburn: Tueruvu Bīsuto) is an ongoing Japanese action adventure shōnen manga series written and illustrated by Okayado.[a] The series is published by Fujimi Shobo in Japan, and by Seven Seas Entertainment in the United States.


Touga Eita is a highschool student and video-game otaku. He is the heir to the Touga style Ninjitsu, and he has never kissed a girl. All this changes when a voluptuous girl with wings and taloned feet named Aero appears and calls on Eita to help save her people-the harpies of Re-Verse-from the merciless onslaught of giant robot monsters known as Gigas. Aero reveals that she was sent to find him, by his missing brother. Eita will follow his newfound harpy friend into a whole new world, filled with monster girls and fantastical creatures beyond his wildest dreams.


  • Eita Touga (とうえい, Tōga Eita): A teenage boy who just wants to be left alone to play video games. His grandfather is a ninja, who wants him to inherit the dojo (despite his refusal to do so), and trains him every day. Touga suffers from a severe inferiority complex, due to his elder brother seducing every woman he comes into contact with. After being summoned to Re-verse, he obtains a gauntlet from Asterio that has the power of fusing with any of his companions, to increase his powers.[2]
  • Aero (エアロ, Earo): A female Harpy who asks Eita to help her save her world, taking him to Re-verse and becoming his first traveling companion.[2] She is the first to fuse with his gauntlet, providing him with extreme speed and strength.
  • Jawea (ジャウェア, Jawea): A female Harpy war leader who has her doubts about Eita, but joins him nonetheless as his second traveling companion, and eventually comes to trust him. During the battle for the fish-people's village, she lost her right wing and decided to leave Eita's party. It should be noted that before leaving she exchanged email addresses with Eita.
  • Asterio (アステリオ, Asuterio): A female Minotaur and master blacksmith who forges a new gauntlet for Eita and later joins him as his third traveling companion.[3] When she fuses with his Gauntlet, she grants him the ability of metal remolding.
  • Steela : A Sea witch, with the lower half of an Octopus. She joins them and provides them with transportation in the form of her house, a huge hermit crab, whose shell functions as her house. She sleeps in a jar.
  • Freki : A member of the werewolf clan, and the fifth addition to Eita's gang. Freki is the werewolf clan's strongest lone wolf, due to the fact that she hunts alone, resulting in her feared reputation, this is actually a façade, and she is really just very shy. She attempts to start a conversation with Eita when trapped in a cave, but only distances herself. They later escape with the golem. When Freki combines with Eita's gauntlet, it allows Eita to control and utilize smoke.
  • Theta : A golem that Eita and Freki find inside the cave they are trapped in. It is revealed that she made the cave after her mechanized suit was damaged. She asks the pair to help her repair it by giving her materials that can be absorbed by the suit. She joins Eita and Freki after they are rescued. Soon after, she sheds her mechanized suit and reveals her true form, a small girl with large metallic hands, before proceeding to help Eita take on the Divine General Vajra and it's pilot, Hunter.
  • Kouki Touga : Eita's elder brother, his endless womanizing is what ends up turning Eita into a recluse. Not wanting to inherit his grandfather's dojo, he left a year before the story begins on a "worldwide-girl experiencing trip". It is revealed that he actually came to Re-verse, his current location is unknown.
