When the hustle and bustle of the comic exhibition ended, Lin Xiaomo and three friends woke up in a white light and found that the world had been turned upside down.
On the streets of Yokohama, supernatural powers are constantly clashing; the demon slayers' blades are shining with the fire of faith; within the barrier of the Magic College, undercurrents are raging... Not only have they traveled through time, but they have completely transformed into their own COS characters - Dazai Osamu's strategy, Nakahara Chuuya's gravity, Edogawa Ranpo's wisdom, and Yosano Akiko's healing, all added to them.
However, behind this "gift" is a heavy mission. A mysterious being named "Mirror of All Realms" informed them that they have become "world restorers" and must go to those story lines that are on the verge of collapse due to the invasion of "high-dimensional poisons" such as "travelers" and "system holders" to set things right.
But repairing the world is far from simply killing monsters and upgrading. They must:
Walking the tightrope between performance and self: Being deeply affected by the personality of the character, when should you enter the drama and when should you wake up?
Making a choice in an ethical dilemma: cold-bloodedly "fix" everything, or take the risk and find a better possibility?
Facing the threat from "comrades": Other teams of restorers have different philosophies. Is it difficult to tell whether they are friends or foes?
From the battle of wits in "Bungou Stray Dogs" to the faith in "Demon Slayer", from the redemption in "Jutsu Kaisen" to the questions and answers in "Fate/Zero"... Their footprints are all over the world. Lin Xiaomo gradually discovered that their journey through time was no accident, and that the source of the collapse of all worlds pointed to a common secret.
