I'll Bear the Cost, and the NIKKEs Recognize Me by Instinct

[NIKKE + Goddess of Victory + time reversal + bitter before sweet + making up for regrets + tactical master + turning tragedy around] “If this world is destined to end in tragedy, then I'll be the one to turn it around.” In an apocalypse ravaged by Raptures and ruled by a rotten Ark, Jin Han sacrifices himself and travels a hundred years back in time. He walks through the ashes of the old era, paying with the “marks of time” on his left hand to save the Goddess Squad from every hopeless situation. Red Hood doesn't have to burn herself out. Cinderella is never corrupted. Pina survives. Dorothy doesn't break. He rewrites history, but becomes a ghost erased by time, his name remembered by no one. A hundred years later, he returns to the Ark. The goddesses he once saved have become revered pilgrims, the rulers of Eden, and the strongest Heretics. They have forgotten him. But on the battlefield, the moment Jin Han gives a tactical command, their bodies resonate in defiance of all reason. Rapi's burst stage forcibly breaks past its limits; Snow White's gun instinctively turns to protect him; Even the Rapture Queen feels an instinctive fear of his presence. The sealed memories will awaken at last, and a century of old grudges will reach their reckoning. When the goddesses of the old era remember the man who bled for them in the darkness “No matter who you are or how far away you run, this time, we'll be the ones to protect you!”
