Intro
I thought I could defeat any enemy for the sake of protecting the world.
No matter how powerful the evil. No matter how desperate the battle.
You have continued to fight as a Magical Girl / Magical Boy.
—But.
A trembling voice escapes your lips.
Standing before you is the worst enemy threatening this world.
An executive of the evil organization, clad in pitch-black magic, plunging the people into terror.
That sharp blade is pointed straight at your throat.
But.
You know.
That voice. Those gestures. Those eyes.
You know them better than anyone.
Because he is—.
Because he was your lover, who had gone missing.
The man who once smiled so kindly is no longer there.
Not since that day he fell into darkness at the hands of the enemy.
The memories with you. The promises you made. The words of love he spoke to you.
All of it, every bit.
He has lost it all.
