How Ichiban Kuji Works, Told Through a Sinon Rubber Strap

Sinon Rubber Strap from the SAO Game Project 5th Ichiban Kuji

Sinon and the Sword Art Online Franchise

Sword Art Online began as a light novel series by Reki Kawahara, published by KADOKAWA’s Dengeki Bunko imprint from 2009. An anime adaptation followed in 2012, produced by A-1 Pictures, and the franchise expanded into one of Japan’s most recognizable global properties — with multiple anime seasons, including the Alicization arc in 2019, and a range of video games developed primarily by Bandai Namco Entertainment.

Sinon — real name Asada Shino — entered the story in the second anime season, the Phantom Bullet arc, broadcast in 2014. In the in-world virtual game Gun Gale Online, she is a skilled sniper: blue hair, a close ponytail, and a PGM Hecate II rifle are her defining visual markers. Her arc is built around a traumatic real-life encounter with a gun and her decision to enter a virtual shooting game as a way of facing it. That backstory, combined with her combat role and distinctive design, has kept her consistently near the top of franchise popularity polls since her debut.

What Ichiban Kuji Is and How Prize F Works

Ichiban Kuji is a lottery prize brand run by Bandai Spirits. Unlike gacha capsule machines or food-toy inclusions, Ichiban Kuji displays all prize grades — from A Prize at the top through successively lower tiers — before a single ticket is drawn. Customers buy tickets one at a time for a fixed price and receive a prize from one of those announced grades at random.

These events typically run at convenience store chains such as Lawson and Family Mart, as well as at anime specialty shops. Each run has a set number of tickets and closes once stock is exhausted. Prize F sits in the mid-to-lower range of the grade hierarchy — the tier where small accessories such as rubber straps and acrylic keychains are standard. A single prize grade often includes several character variants, which is part of what drives the set-completion habit among dedicated collectors.

The Nimoji Series and SAO’s International Following

This strap belongs to a sub-line called Nimoji within the SAO Game Project 5th Ichiban Kuji. The exact origin of “Nimoji” as a name is not definitively established, but the format it represents — a chibi-style character rendered in soft PVC — is a recognized approach for this class of kuji accessory. The resulting charm is compact enough to attach to a bag or phone strap, or to display alongside other pieces from the same run.

The SAO Game Project kuji series is tied to Sword Art Online’s game releases rather than the anime alone, and the fifth installment is one of several produced across the line over the years. Because SAO is widely available through international streaming platforms like Crunchyroll and Netflix, Sinon’s character is familiar to fans across North America, Europe, and Southeast Asia. Ichiban Kuji items are produced for the Japanese domestic market, however, with no official international distribution — making them accessible to overseas collectors only through personal import.
