◆ Story
“In a world rewritten,
no one remembers the truth anymore.”
Muni wakes up in a school she’s never seen before.
She doesn’t remember who she is — or why she’s here.
Rumor says this academy hides a secret experiment,
and her arrival sets destiny’s gears in motion—
every choice changes someone’s fate, including her own.
To find the truth.
To save one life.
She must erase another’s existence.
