The 2nd costume of Nijisanji EN's Vox Akuma, as seen in post #6246618 and released on April 22, 2023.
This costume gives him a more demon-like appearance in line with his pre-Luxiem lore, with black and skin-covered gradient horns and pointy ears. He wears a black and red gradient kimono with the same floral print as his default costume, and it's held by a gold obi where he also holds a katana. His kimono also exposes his chest area to reveal his abs and sizeable pectorals. He also has a hagoromo, and his sandals are now clog sandals. His hair is up in a ponytail and his forehead is exposed to show off a red forehead mark.
