Why fans love it: It combines the “big sister / big JK” energy with actual useful life lessons — not just drama.
Last week, Ayumi made good on her promise. The event, dubbed “Project: Amethyst,” was revealed across her social channels in a cinematic 12-minute video titled “Big JK, This is for You.”
Here is how she returned the favor, broken down by lifestyle and entertainment pillars.

She is bridging the gap between lifestyle (healthy living, financial planning) and entertainment (production, directing, acting).
In the fast-paced ecosystem of Japanese digital entertainment, “favors” are often transactional—a retweet here, a brand plug there. But every so often, a story emerges that transcends the typical influencer exchange. This is the story of Big JK and Amemiya Ayumi, a tale of reciprocity that has captivated millions, not just for its scale, but for its soul. Last week, Ayumi made good on her promise
It started three months ago when Big JK, a towering figure in Tokyo’s nightlife and streetwear vlogging scene, extended a career-altering hand to rising star Amemiya Ayumi.

In an era where lifestyle content often feels curated to the point of emptiness, the “Big JK / Amemiya Ayumi” exchange stands out for three reasons:
Ayumi collaborated with underground Tokyo designer Hanae Mori (no relation to the late couturier, but a rising star in gender-fluid streetwear). She commissioned a 10-piece capsule wardrobe for Big JK, inspired by his two loves: vintage Americana and Edo-period samurai armor.
