Raishin

Raishin is a young man with black hair and a tattoo of a youkai on his back. He is a descendant of Ushio and Tora, two legendary warriors who fought against the youkai. Raishin is determined to follow in their footsteps and protect the world from the evil youkai. One day, Raishin is attacked by a group of youkai. He is outnumbered and outmatched, but he refuses to give up. He draws his sword and fights back with all his strength. Just when it seems like he is about to be defeated, he is saved by a mysterious girl. The girl introduces herself as Akari. She is a youkai hunter, and she has been tracking the group of youkai who attacked Raishin. She offers to help him train so that he can become a stronger fighter. Raishin accepts her offer, and the two of them set off on an adventure to defeat the evil youkai. Along the way, Raishin and Akari learn more about each other and their respective powers. They also learn more about the world of the youkai, and the dangers that it poses. As they grow closer, they develop feelings for each other, but they know that their duty to protect the world comes first
