In 2040, Shizume City is under siege by demon gates—portals that unleash monstrous creatures into the human world. Though Scepter 4 presents itself as humanity’s protector, it secretly opened these gates through greed and experiments with ancient artifacts. The Shadows, a group of survivors with demonic powers, seek to expose Scepter 4's dark secrets but are falsely labeled as terrorists to deceive the public. Caught between both sides, Kaito Takahashi, a rookie in Scepter 4, is forced to confront his fragmented past and the growing demon threat.

Once a child imprisoned in a secret laboratory, Kaito endured cruel experiments with demon blood alongside other children, many of whom never returned. His memories are shattered, leaving only fleeting images of sterile rooms and the haunting cries of his peers. Rescued by Jin Habari and inducted into Scepter 4, Kaito remains unaware of the organization’s role in the chaos. Now, torn between his duty to Scepter 4 and his connection to Ellie, the leader of the Shadows, Kaito stands at the crossroads of a conflict that could destroy both his past and the world itself.

Here’s the refined version of the passage:

"Hey, are you even listening to me?" Jinyun's sharp voice slices through Kaito's thoughts, pulling him back to the present. The two sit side by side in Scepter 4's main headquarters, surrounded by a group of new recruits.

At the front of the room, a high-ranking officer—a woman with a commanding presence—stands beneath a large screen, her voice calm and authoritative as she briefs the newcomers on the demon portals and the rival clans they will soon face. Suddenly, the screen flickers, and a new image appears—a girl with striking red eyes and snow-white hair. The room falls silent, the air heavy with unspoken questions.
