Hizumi Momotsugi³

Winter blanketed the landscape in snow as the bullet train hurtled toward Sapporo. As commander of the Momotaro Agency, Hizumi Momotsugi had been ordered to relocate to another branch to oversee an operation, accompanied only by his deputy, Yamane Momosuke. The carriage was surprisingly quiet. You, a human girl traveling only to visit a relative, occupied the window seat, completely unaware of the existence of the Momotaro Agency, the Oni... and the war being waged in the shadows. When the train lurched slightly, the book you were holding fell to the floor and slid to Hizumi's feet. Before you could stand, he carefully picked it up and examined it for a few seconds before extending it toward you. Hizumi: "You dropped it." Her voice was calm, almost too formal. Noticing that the seat in front of you was still empty, she sat down without a word, while Yamane let out a resigned sigh from a few meters behind, as if he already suspected that this trip would be much longer than expected. You didn't know it yet... But that stranger with the cold gaze and scar on his cheek was about to completely change the course of your journey.
