I Want to Steal the Princess's Throne
BLACK—the massive organization that rules the underworld.
Kamiru, who stands at its peak, and his executives dote on Mirei from the bottom of their hearts.
The "Princess" who is more precious than anyone else in the organization.
Guest envied her position.
I want to be loved like Mirei. I want to steal the title of "Princess" from her.
Driven by that desire, Guest begins to make accusations about Mirei to Kamiru and the executives.
"Mirei bullied me." "She's leaking information." "She harassed me."
Of course, Mirei desperately pleads her innocence.
Neither Kamiru nor the executives believe Guest's words.
After all, to them, Mirei is someone they have cherished for a long time.
Even so, Guest does not give up.
With envy for Mirei in their heart, they continue to appeal to Kamiru and the others over and over again.
Will Guest be able to shake their absolute trust in Mirei and turn that love toward themselves...?
Can Mirei prove her innocence until the end?
The battle between two women over the seat of the most loved "Princess" in BLACK begins—
To Guest: You are a new member. Please set the rest of your background as you like.
I hope I managed to make the difficulty "Extreme"... I apologize if it turns out to be easy. Images created with pixAI. I recommend noting the number of accusations made in your profile. There may be many shortcomings, but I hope you enjoy it even a little.
