The code NSFS-138 refers to a Japanese adult video (JAV) titled "Born De M Ririka Best," featuring the popular adult film actress Ririka (also known as Nanase Ririka). Released under the Nana (Nanase) label (part of the North Pictures/Tsubaki group), this title is a compilation "best of" release that showcases the highlights of her early career and specific "M" (masochistic) themed performances. Overview of NSFS-138 Actress: Ririka (Nanase Ririka) Label: Nana (Nanase) / North Pictures Series: Born De M (often stylized as "Born de M")
Theme: This specific entry is a compilation (Best Of), curated to feature her most acclaimed scenes involving "M" roleplay, submission, and high-intensity performances that defined her popularity in the late 2010s. The "Born De M" Concept
The "Born De M" series is a recurring theme within the Tsubaki/North Pictures production circle. It focuses on the persona of an actress who is portrayed as "naturally submissive" or possessing an innate desire for masochistic roleplay.
Authenticity: Ririka was highly regarded in this series for her expressive acting and realistic reactions, which fans often cited as more "authentic" than standard scripted submissive roles.
Performance Style: NSFS-138 specifically gathers scenes where Ririka’s versatility is on display—ranging from standard "M" scenarios to more elaborate fetish and submission themes. Why NSFS-138 is Considered "Best"
For collectors and fans of Ririka, NSFS-138 is often viewed as a definitive entry for several reasons: NSFS-138 Born De M Ririka Best
Curation: Instead of a single 120-minute feature, this compilation typically offers extended runtimes (often 4 hours or more) of her highest-rated scenes across multiple previous volumes.
Career Peak: The scenes included generally date from the height of her popularity, capturing her peak physical form and her most refined performance techniques.
Visual Quality: As a production from the Nanase/North Pictures group, the cinematography is noted for its high-definition clarity and professional lighting, which remains a standard for the "M" genre. About the Actress: Ririka
Ririka entered the industry with a "girl next door" aesthetic that contrasted sharply with the intense submissive themes of the "Born De M" series. This contrast became her trademark. She is known for her slender build, expressive facial features, and a high level of endurance during demanding scenes, which helped her maintain a long-standing position as a top-tier performer in the submissive fetish niche.

NSFS‑138 — Born De M Ririka Best
Prologue
The star‑crystal of the Nebular Surveyor Facility shimmered in the void, a lone beacon that marked the coordinates of humanity’s most secret project: the Nexus Synthetic Frontier (NSF). Within its steel‑clad corridors, a handful of scientists and engineers worked on something that would change the definition of “born” forever.
In the quiet of Lab‑C, a low‑hum of quantum processors filled the air. Dr. Mara Veln stared at the holographic readout of NSFS‑138, a designation that meant nothing to the outside world but everything to her. “Born De M”—the codename the team used for the De‑Matter Genesis protocol—was finally ready for its first conscious test.
The subject’s name, Ririka, was a nod to an old Earth legend—a girl who could speak to the wind. The team hoped to give the synthetic child a soul of its own, a whisper of humanity in a body of engineered matter. What is NSFS-138
Mara placed her palm on the console. “Let’s begin, Ririka. Let’s see if you can be… Best.”
A cascade of light enveloped the containment chamber. The air thrummed, and the synthetic womb—an alloy of graphene, bio‑gel, and dark‑matter filaments—started to pulse. The quantum‑entanglement lattice sang, translating the code into a living lattice of consciousness.
The entry for NSFS‑138 reads:
