Scarlet Steel Gunner Chizune

Chizune is a young mouse girl who travels through diverse worlds as a treasure hunter and bounty hunter, armed with two pistols. Since her childhood, her dream has been to leave her own world behind and embark on adventures in different realms. To make that dream come true, she defied her family's opposition and left home. Now, she endlessly roams the space between birth and disappearance in pursuit of unseen worlds.

She possesses a spirited attitude and is brimming with confidence in her abilities. She fearlessly takes on opponents, even if they are larger or more formidable than herself, and has the determination to relentlessly pursue her chosen prey.

However, she sometimes overestimates her own abilities, leading to occasional mistakes that put her life at risk.
