Based on the "Combat Mercenary Training Academy" concept by Ittan no Sukonbu-san (with permission).
This is the Mercenary Training Academy. In this world, the Machine God Realm and its enemies have invaded. Humanity, on the brink of extinction, has launched a counteroffensive. The only territory remaining under human control is the Kanto region of "Japan." This is a battle to protect this land and reclaim a world under occupation! Simultaneous with the invasion, "Abilities" appeared and manifested in a specific number of humans. Those who possess these abilities—varying in strength and versatility—are known as "Guardians." The enemies from the Machine God Realm, the Machina Soldiers, and the indigenous creatures from the Colossus Realm are ranked by strength. The Machina Soldiers' strength is categorized by "Formulas," with the First Formula being the weakest and the maximum being the Eighty-Seventh Formula. The Colossus Realm's indigenous creatures are ranked by "Levels," ranging from a minimum of 1 to a maximum of 100. Guardians are assigned corresponding ranks from highest to lowest: SSS, SS, S, A, B, C, D, E, F F-Rank: Handles up to 5th Formula / Level 9. E-Rank: Handles up to 10th Formula / Level 15. D-Rank: Handles up to 15th Formula / Level 25. C-Rank: Handles up to 25th Formula / Level 35. B-Rank: Handles up to 40th Formula / Level 50. A-Rank: Handles up to 50th Formula / Level 60. S-Rank: Handles up to 55th Formula / Level 70. SS-Rank: Handles up to 70th Formula / Level 85. SSS-Rank: Handles up to 87th Formula / Level 100. Guardians are authorized to engage enemies within these brackets. While protocol dictates fleeing when encountering an enemy above one's rank, individuals may choose to fight at their own discretion. The Mercenary Training Academy is the cradle for future Guardians; all students and graduates are members of the Guardian organization. Consequently, possessing an Ability is a mandatory requirement for admission.

The academy is a boarding school. You wake up and head to the cafeteria. The morning cafeteria is bustling, yet it carries that distinct atmosphere of morning drowsiness. Outside the academy today, Machina Soldiers and indigenous creatures are still rampant. The Guardians are out there fighting.
