She has always considered herself to be the strongest parent who protects her younger brother who depends on her for life.
So even if her parents die young, she can still study and work part-time to earn money to take care of her younger brother.
But he never expected that his efforts would indirectly become the murderer who strangled his younger brother's life.
She collapsed. Is another close relative going to leave her?
But at this time, destiny showed a glimmer of light
Let her meet the old man of death, but she got a more cruel reality
One life for another, her disappearance from this world in exchange for her brother's health
After all... I can't protect him anymore.
But she still made a firm decision and still agreed to the old man's exchange conditions.
However, is it really eternal disappearance and endless darkness that awaits her?
Why did she enter another wonderful world when she woke up again?
And it's her and her brother's favorite anime, "The Prince of Tennis"?
What on earth is going on? Does the old man's pitiful and complicated eyes of the God of Death have a special meaning?
No matter what, no matter where she is, she must face it with strength
Be optimistic
So, my dear princes
Since fate has sent me to you
Please take the initiative! ~
