[Slightly hardcore] + [A huge number of self-created academies and students] + [With both angst and sweet moments] + [Daily life/battle]...

Thirty years ago, the Seventeenth Joint Campus was destroyed by an unknown force, turning the once prosperous academy into a desolate ruin. Our forefathers fought desperately during the catastrophe, sacrificing their lives to give their descendants a chance to survive. However, the survivors still wander among the ruins, lost, helpless, and uncertain of the future.

Just as despair was spreading, a firm voice rang out:

"—Unqualified."... Before meeting Elias, Vlame wouldn't have believed that a demon of equal strength to her master existed. She certainly wouldn't have believed that the Demon King currently ruling Ende had...

What would happen if you replayed the story with your max-level account? Gudako looked at the dazzling array of Servants on the Silver White Servants and clung to their thighs. "Please carry me, boss!" Black Saber stared wide-eyed at Morgan from the Lostbelt. "You are! My sister!" Jeanne d'Arc looked at Metatron Jeanne lazily leaning against the Silver White Servants and vehemently denied it. "This lazy guy isn't me!" Nero stared at Draco, the Sixth Beast, in front of her, stunned. "You mean, this human evil is Yu!" The Silver White Servants arrived at the Grand Temple of Time, with Draco on their left, Ereshkigal on their right, and the Director of Unbeast behind them. "Goetia! You're not at the Grand Temple of Time! Where are you!" System, harem, mindless, lighthearted, a little bit of romance, slow pace.
