The Daimakai (Great Hell)

Yamino Ryuuse

Yamino Ryuuse A sorcerer and servant of Gokurark. When he fails his first escape attempt, he slips Yamino Ryuuse out to work on freeing him. Yamino Ryuuse then posseses a skeleton in a school science lab(seemingly the same school that the Ganbare team attends) and summons Makaijuu(Hellbeasts) via a magic tome and the chalkboard in the lab. He also created a human-looking form for subterfuge purposes. (Mostly information collecting) After his master's defeat, the surviving portion of Gokuark embeds itself in him, granting him more power and a slightly altered form. From this point on, until the other two demons free Gokuark from his body and restore Gokuark's power, he is able to convert pre-existing objects directly into Makaijuu. During this period, he has a bout of amnesia, during which he(in himan form) and Aiko fall for each other. After regaining his memories, he seems to forget about it until a picture of them brings it back. He denies it, but at the very end it does seem as if he finds a "heart" after Gokuark betrays him and turns him into a koala.

The Three Great Demons

Gokuark The first of the three demons, originally sealed in the shrine at Koutarou's home. The leader of the three. After his initial defeat by the Ganbare Team, he hides himself within Yamino Ryuuse, until his revived brothers pull him free once more.

Seiyark The second of the three demons. He had been sealed by the El Retendor statue in Rio de Janeiro, Brazil, until Yamino Ryuuse broke the master seal in Japan and freed him and Retsuark. Has control of Lightning.

Retsuark The last of the three demons. He had been sealed near the Great Pyramids of Giza until freed by the breaking of the combined seal in Japan. Has the power of demon summoning.
