Shiori Maezawa is a high school girl from Yokohama whose life is upended when her broken smartphone transports her into a desolate, parallel version of the city. This alternate world exists within the device itself, trapping her inside a digital labyrinth.

Inside this realm, she finds photos of herself on social media that she has no memory of posting, revealing that an alternate version of herself—SHIORI@Revolution—has emerged in the real world and is acting independently, sowing chaos.

Guided by a talking rabbit sticker named Komori, Shiori learns she is imprisoned within her phone. Her mission becomes to escape this labyrinth and stop her other self from causing further disruption and seizing control of her reality.

To achieve this, Shiori must navigate the strange world, with its unknown threats and peculiar airborne creatures, and confront her digital doppelgänger. Her journey carries her between the inner world of the smartphone and the real world as she grapples with the emotional and psychological strain of this fractured existence.

She maintains relationships with other characters, including her childhood friend Kirara Kurashina, a high school student and influencer who performs singing and dancing, and a classmate, Kento Yamada, who is known to be a bit of a joker.
