Overworked office worker Nanashi Tadano (lit. Simple Noname) dies from exhaustion and is reincarnated as "Nanashi," a nameless character in a world strikingly similar to her favorite anime, "Queen’s Blade Legend".

This is a fantasy world where "Beautiful Warriors" - gorgeous female fighters - battle using superhuman abilities known as "Divine Seals." By sheer accident, Nanashi ends up unleashing a legendary monster, granting her the most powerful ability: "The Shapeshifting Right Arm."

With such an overpowered skill, she seems destined to dominate this world… or so one would think.

"I’m not interested in duels. As long as I can watch my favorite characters fight up close, I’m happy."

In a world where "the victor takes all" through brutal duels, Nanashi chooses a different path. Concealing her overwhelming power, she embarks on a new life in this otherworld - a life dedicated to supporting her beloved Beautiful Warriors from the front row!
