As its title suggests, PRIVATE HOUR offers a special moment shared between just you and her through the camera’s lens. Across five settings—including a sophisticated office, a softly inviting bedroom, and a sun-drenched rooftop—the themes of “cool” and “beautiful” reveal a succession of poised, self-assured expressions that show a different side of her. Highlights include black lingerie draped in light and shadow filtering through the blinds, deep green lace lingerie revealing an unguarded intimacy reminiscent of just waking up, and a white leotard-style outfit that she herself describes as “a fresh and exciting discovery.” Each photograph, captured like a scene from a film, draws the viewer into her private world. Usually also the one behind the viewfinder, she steps in front of the camera to reveal new facets of herself in this photobook.

Rui spills a drink at the café. She beckons you over and gazes at you with an anime-like voice that doesn't match her mature body, saying "I spilled it" and "What should I do?" Without looking away, she deliberately and slowly brings a donut to her lips. What she really wants to eat is you.

Only the light filtering through the blinds falls into the room. Countless white lines trap Rui in a cage of stripes. Wearing nothing but underwear, a garter belt, stockings, and high heels, Rui strikes a pose like a female panther. Her body quietly targets you.

Rui, in her underwear, professes "No, I don't wanna get up" in her cute anime voice. Her soft-looking skin glows while she rolls and writhes on the bed. Her chest and butt each assert themselves. That dissonance keeps shaking your emotions and blows away your sleepiness.

The white bodysuit wraps smoothly around her contours, as if merging with her skin. She leans her upper body against the cool marble and slowly raises her lower body. You feel a tightness deep in your chest, a tender affection, at the sight of those white, round fruits appearing before your eyes.

Rui is doing desk work at the office. She suddenly smiles at you and asks, "What are you looking at?" She lifts her legs onto the desk, revealing the secret between her thighs. Her pantyhose, half removed, clings to her buttocks, forming hills of flesh. And you, tormented with desire, go back to work again.

Behind-the-scenes footage. Only the hidden lens knows her most unguarded moments. Unlike the expression she directs at the camera in front of her, her relaxed lips, her disheveled collar. Maki's raw allure, stripped of all pretense, is quietly recorded without her noticing. Here exists another side of her that you won't find in the main feature.

In a digest of just under 30 minutes, we get a glimpse into everything behind the scenes and Tsumugi's true, unguarded self during the shoot. Filming took place over three days in Atami during the summer. Shooting in the height of summer was extremely tough, but what left a lasting impression was the sight of Tsumugi chatting with the staff, her large breasts softly swaying each time she laughed.
