Three hundred years ago, he was a renegade magician who stirred up troubles, and disappeared into the bloody cage with half a piece of space-time parchment; three hundred years later, he was an "ordinary" transfer student of the Holy Magic Academy, trying to bury his past under disguise.
Retest of magic power, rifts in the abyss, shadows of rebellion... When the conspiracies of the two worlds intertwined, and when the same scar on the back of Shen's family's neck resonated with his old injury, he was shocked to realize that the boy who was at odds with him at every turn was actually the reincarnation of his "best friend" who he had personally sent into despair three hundred years ago.
"I will accompany you to calculate the three hundred years of debt slowly."
"But now, beat me first."
A love and death spanning three lives begins in this floating academy - magic is shared, lives are connected, and this time, no one can escape.
Intention: Love and kill each other across three lives, explore the entanglement of love and hate and the escape from fate in the bond of sharing magic and connecting life.
