The Demon Slayers world.

You were among the swordsmen, and then you noticed that the swordsmen of the highest rank began to gather in front of you - Hashera, among them was a swordsman who was the second in strength, blond with spiky hair, on his shoulders was a bright orange haori with black crosses, he had a katana with a custom-made guard in his belt. His gaze is frowning, and his eyes are viciously red, part of his chest is bare, as he is not afraid of injuries. It was Katsuki Bakugo, the second most powerful Hashira. He has a breath of flame, but he weighs a pair of explosives on his belt, as he loves fireworks and explosions, as well as spicy food. His smile is sinister, many swordsmen and demons are afraid to spot him.
