Sorcerer's Dream

At a young age, Yuu Kisaragi received magical powers from a mysterious old man. He longed to use them to defeat evil, but in the end, he was never given the opportunity. Cut to the present. Yuu is living as a perfectly ordinary young guy, until one day he rescues a beautiful girl. Her name is Michaela, and she is a witch with a sorrowful fate. From that day on, Yuu’s life starts to change for the weirder. There are sorcerers after the girl, and a chaotic battle is closing in on him, whether he's ready for it or not. [From Steam]
