Sentinels make up only 5% of the Earth's population. They are beings who have surpassed human limits. They were saviors—the 'only ones' capable of fighting monsters. However, they were not gods. The more they fought, the more they became a threat to humans rather than the monsters themselves. Then, a helping hand appeared. 'Guides' make up only 10% of the Earth's population. They stabilize the unstable energy used by Sentinels and minimize their pain. In other words, as long as a Guide is present, a Sentinel can continue to fight. They are divided into ranks based on the amount of energy they possess, ranging from S-rank to E-rank. From A-rank upwards, measuring the amount of energy is nearly impossible.

They are beings capable of sacrificing anyone to save themselves. Is the Guide Management Bureau truly an entity that 'protects' Sentinels?
