In a universe veiled in secrecy, a rare cosmic phenomenon known as the "Crimson of Lunar Eclipse" casts an enigmatic glow upon the moon, foretelling a time of both wonder and peril. Little do humans know that this awe-inspiring event is a harbinger of impending change, as ancient forces concealed within the shadows manipulate the destiny of worlds.

Within the vast cosmos, two factions exist in constant conflict—the Lunar sentinels in the Cosmo state of the moon, wielding mysterious powers, and the Solar Sentinel in the Cosmo state of the sun, bearers of benevolent light. For millennia, they have adhered to a strict code of secrecy, concealing their true identities from the inhabitants of planets. However, as the final Crimson Lunar Eclipse approaches, tensions escalate, and the Lunar Sentinels grow ever more ambitious in their pursuit of dominion over the cosmos.

Yet, amidst the gathering storm, hope remains. Prophecies speak of a chosen Guardian—one blessed by the entire galaxy—to safeguard the delicate balance between good and evil. Unexpectedly, this chosen Guardian emerges as a seemingly ordinary boy from Earth.
