Their restricted abilities are refreshed every week.

After fifteen years of hard work, Shirakawa Haru was reincarnated after being randomly stabbed in the neck by a passerby in a swordsman's uniform before he had time to enjoy his life.
Seventeen years later, he has a strong physique, a strong will, excellent academic ability, and extraordinary charm. He can even become the final boss of the sword battle suit.
So he was full of confidence:
"——Please, let me enjoy my youth for once."
But gradually, Shirakawa Haru discovered that something seemed to be wrong with this world.
Her younger sister, Yuki Suho, can adjust other people's favorability at will and hypnotize others remotely.
Oguruma, a new transfer student, can stop time all over the world with a wave of his hand, and then do whatever he wants.
The seemingly dignified and cold vice-president Toyokawa Shoko can actually change common sense and play scary games in private.
……
What's even more outrageous is that Shirakawa Haru discovered that their restricted abilities not only evolve, but are also randomly refreshed once a week!
This is a market, the other side is fully open!
Facing them who were surrounding her and sharpening their knives, in order to avoid the ending of being divided into five equal parts, Shirakawa Haru took a half step back and turned around and ran:
"Youth and the like should be left for others to enjoy!"
