My Undead Lich and Me

Betrayed by the man he had called his best friend and fellow Hero after defeating the Church's number one enemy, the Lich of Dekoir. Keino wakes up having lost all the skills he had gained over the two years he had spent in Kyriaki since being summoned from his own world with two of his classmates. Now he finds himself awakening in a body that is not his own, the only way Keino will be able to take his revenge now will be through siding with the person he would least suspect.
