A MASTERLISE Uzui Tengen

The first image of the lottery shows Uzui in full battle mode. He stands with his legs planted wide, both chained cleavers raised, wearing his sleeveless uniform, jewelled headband and the bold make-up around his left eye. The MASTERLISE line is Bandai Spirits' larger, more detailed prize figure range, so expect a figure with real presence on a shelf, with sculpted muscle definition and plenty of movement in the ribbons and chain. Given how popular Uzui has been since the Entertainment District arc aired, this is likely to be one of the most wanted prizes in the set.

Siblings of Demons: the full line-up is coming

The subtitle "Siblings of Demons" points to Gyutaro and Daki, the Upper Rank Six demons who share one rank and fight as a pair. Bandai Spirits has confirmed that the full line-up has been decided but is holding back the details for a later announcement, so the remaining prizes have not been revealed yet. Previous Demon Slayer kuji have mixed figures with towels, acrylic stands, art boards and small charms, and the arc's neon-lit pleasure district setting gives plenty of scope for striking designs. We will share more as soon as the official line-up is published.

Happy birthday, Uzui Tengen

The official Demon Slayer account celebrated the day with a new ufotable mini-character illustration of Uzui. It shows him in a cheerful chibi style on a theatre-style stage, framed by a "Happy Birthday" arch and dated 10.31. It is a fitting tribute to a character who loves to be flashy.

Uzui Tengen Birthday Festival 2026

ufotable is running a full Uzui Tengen Birthday Festival 2026. This year's theme is "everyone is the star on their birthday", and the new birthday illustration shows Uzui taking centre stage. The ufotable WEBSHOP has released four event goods, including a three-dimensional stage acrylic stand that recreates the illustration and a showy rosette. In Japan, the Demon Slayer collaboration cafes are giving a luncheon mat to anyone who orders the birthday menu, ufotable Cafe TO GO, ufotable DINING and ufotable CINEMA are serving limited drinks with novelties, and the ufotable MOCKTAIL BAR GINZA has a special birthday mocktail that comes with a coaster.

An illustration gallery and a birthday stream

To round off the celebrations, ufotable has opened an Uzui illustration gallery on its Pinterest page, collecting many of the character illustrations it has drawn of him over the years, including new artwork. There is also a special birthday stream on the ufotable YouTube channel that looks back at Uzui's scenes from the Tanjiro Kamado, Unwavering Resolve Arc through to the Hashira Training Arc. The stream is only available until 23:59 Japan time today, which is 14:59 UK time.

The TV rebroadcast continues

For anyone following the full TV series rebroadcast in Japan, Mugen Train Arc episode 4, "Insult", airs on Fuji TV and other stations on Sunday 1 November at 9:30 Japan time. It is a good reminder of how the story builds towards the Entertainment District arc that inspires this new kuji.
