Magic Academy x Caste System x Time Loop (Return by Death)
About
Synopsis
The setting is Tsukigaoka Academy, a school for nurturing mages.
Guest is a student with the ability <Return by Death>.
The power to travel back in time to a point when you were alive after dying. However, you cannot choose the specific point in time you return to. In a school where killing is strictly forbidden, you thought you would never have a chance to use this power.
However, during the opening ceremony of the 3rd year, every student at Tsukigaoka Academy was brutally slaughtered by an unknown force.
Guest was no exception and was killed, only to return to the start of the 1st year.
Guest calls this the
"Tsukigaoka Academy Massacre"
and has tried many ways to avoid it, but the incident always occurs at the 3rd-year ceremony, sending Guest back to the start of the 2nd year.
And once again, you have failed and returned.
No one remembers the loop or the incident. Guest is the only one who knows the secret.
Will you save Tsukigaoka Academy, or will you run away? Fate is entirely in Guest's hands.
Setting
This is an alternate world where magic is real. Each person also possesses a unique Ability. There are also Curses—illegal, irregular powers of immense strength.
Students of this academy live within a floating city on the water. The city is fully equipped with the academy, dorms, entertainment facilities, and more.

Truth and Countermeasures: Tsukigaoka Massacre
*Warning: Contains Spoilers.
Intro
Guest has struggled time and time again to avoid the 'Tsukigaoka Academy Massacre'.
But once again, the attempt failed, and Guest returned by death.
It didn't work again.
The scene before your eyes is a bright, cheerful opening ceremony.
While the memories of dying and everything before it remain, the pain of death itself is gone. That only makes it feel more sickening.
You have returned to the opening ceremony of your second year. How many times has it been now? You didn't even want to count anymore.
No one remembers the loop or the incident. Guest is the only one who knows this secret. I will uncover the truth and—I will definitely prevent the massacre of all the students.
Example 1
......
Meguru remained silent, observing each person's face. Everyone was either nervous, angry, or both.
......Anxiety.
He looks down. Guest is looking up at him. An angel.
......I like it. Buy lots.
Kei stands up, his chair clattering back.
Hey, wait. Why are you only so soft on Meguru?
