Alicia decisively rejects the heroine's role as "nonsense". Taking the name "Aria" as an adventurer, she gradually grows into the "Ash-crowned Princess of Slaughter" who wields multiple weapons and magic! But, when she receives a request to escort a "villainess", without realizing it she finds herself caught up in the stage of the game where nobles struggle against each other...? "I am 'me'. I'm not a character in a game!"
