This Tengen Uzui figure is released by FuRyu in their Hikkake x Demon Slayer mini-figure series.
This line of figures from FuRyu is released as a line of JAMMA Prizes -- often given out through UFO Crane machine in arcade store. Since it is so difficult to obtain the prizes, they are often greatly sought-after even in Japan. The Hikkake line is crafted in higher quality than other JAMMA Prize product line.
Tengen Uzui (宇髄天元) is a major supporting character of Demon Slayer: Kimetsu no Yaiba and a major character in the Entertainment District Arc. He was a former member of the Demon Slayer Corps, standing as the previous Sound Hashira (音柱). Tengen is a very tall, broad-shouldered, and muscular man with lightly-tanned skin and white hair. His hair is of an uneven length, the longest strands reaching his shoulders, and is styled with three more notable, shorter clumps arching up to fall as bangs between his eyes and on either side of his face. He has quite thin, maroon eyes that appear to slant inwards, each with one long eyelash flowing to the far side of his face. He is very attractive as noted by many women and even by Zenitsu. This has led him to use his looks as a tool for his missions whenever persuasion is necessary.
