The adventurer Soyuz accepts a certain request from the guild and meets Lena, a girl whose body is covered in severe scars. Using a mysterious healing power known as "Life Sharing," Soyuz heals her wounds and gives hope to a girl who has long suffered abuse as a slave.

Because of that danger, he believes Lena should choose to live freely on her own. Yet her feelings for him turn out to be far deeper than he expected... Endowed with miraculous power, what choice will Soyuz ultimately make?
