In the "Great Day" group, all members can be divided into two categories: combat mechanical angels that focus on force, and auxiliary polyhedra machines that can be used as weapons to combine with living things. In order to reseal the resurrected "Intruding Demon", the "Great Day" sent different types of auxiliary "Great Day" members to each tribe after uniting the four clans of "Relic Style", "Kaoru Wind", "Lava", and "Jewel Knight", in order to enhance the combat power of each tribe.
The "Great Sun Prismatic" that is derived from the gem was sent to the camp of the "Jewel Knight", and its body contained the power of endless thunder and lightning, like a huge battery.
Through the unique fusion power of the Gem Knights, the leader of the Gem Knights, "Jewel Knight White Crystal", was combined with them, and a new Gem Knight Light Prism was born.
The prism gives the white crystal the power of thunder and lightning representing destruction and fury, coupled with the original outstanding physical strength, the strength of the white crystal can be said to have been qualitatively improved.
The "Great Sun Star", which is good at destruction, was sent to the warlike "Lava" tribe, and this auxiliary Great Sun Mechanical Lifeform, which inherited the performance of the Battle Angel, can be said to be a pure killing weapon.
The Great Sun Star body was combined with the lava tribe's combat expert "Lava Stone Man", using the homologous power used by both lava and the big sun, and a warrior named "Lava Star Gunner" was born.
This time the combination is actually reluctant. In the confrontation with the "Intruding Demon Man", the Oishi Man experienced a fierce battle, not only lost his legs, but also caused the heart fire to be extinguished due to the excessive use of power, in order to continue the life of the Oishi Man, the "Great Sun Star Body" that was supposed to be a combination with the Lava Ruling King was combined with the Oishi Man.
The "Great Sun Sphere" was sent to the Kaoru clan, which was also assisted by the Alliance. Unlike other armed polyhedra robots, the Great Heliosphere is a functional auxiliary mechanical angel.
As one of the few combat-type talents of the Kaoru clan, Liz's activity on the battlefield was recognized by Ōhime, and Liz was qualified to wield the "Ōhi Sphere".
With the power of the same tone, the "Great Sun Sphere" and the warrior of the Kaoru clan, "Kaoru's Swift Wind Liz", gave birth to a new warrior "The Ball Wind of the Great Kaoru Wind".
The "Great Sun Tetrahedron" was sent to the "Relic" tribe. Tetrahedron is an armor-type robot that can take damage in combat in place of the Fitter.
Noelia, the leader of the "Legacy" clan, became the master of the "Four-Sided Sun". According to the plan of the Great Day, the four polyhedra mechanical angels were originally prepared for the leaders of the four tribes.
However, in the process of merging the "Great Sun Tetrahedron" and Noelia, the power of the evil ritual obtained by the "Relic" clan from the "Intrusion Devil" was used, and although a powerful warrior named "Evil Relic Four-Armed Devouring Demon" was born, Noelia also took the opportunity to transfer the evil thought of "Invading the Devil" into the body of the "Great Sun Tetrahedron".
