A full-body illustration of Kazuki Takahashi, the Raijin Hashira from Demon Slayer, in a dynamic battle pose. He is wearing the traditional Demon Slayer Corps uniform, with a blue kamado over it. His black hair with blue tips is flowing, and his blue eyes are fierce. He has a distinct facial appearance, different from Tanjiro. He wields his Nichirin Swords, crackling with thunder energy. The art style is highly detailed, mimicking the Ufotable Demon Slayer anime and Koyoharu Gotouge's manga style. The background shows a stormy night with lightning striking and a traditional Japanese temple in the distance.
