Alive

Akira Hondou was shot to death by the U.S. military for a crime he did not commit. However, he somehow survived and became a teacher at a girls' high school. The objective of his assignment to this school? The key to that is in the hands of Hibiki Tsukishima, an ordinary high school girl in the art club... The story accelerates as Hondou, an out-of-the-ordinary egoistic gentleman, gets involved in his surroundings. (Source: Cygames, translated)
