Ishi ni Usubeni, Tetsu ni Hoshi

Gath is known as the most powerful warrior in the land because of his innate immunity to the deadly poison secreted by magical creatures, which has earned him the name "Iron-blood Gath." During a mission to subdue such creatures, he encounters a young Medusa who is drawn to him because his resistance makes him unaffected by her petrification abilities. In a rare move, Gath chooses to bring her back to the capital with him.
