Xie Chen nodded in agreement. Soul Eaters are really a headache. For not only can they devour grim reapers and humans, but also souls. Well, souls are what they wanted to devour. And it just happens that humans and grim reapers, as well as the animals even, have souls.
So, the Soul Eaters also wanted to eat them.
"You are right." Xie Chen muttered as he and Gu Shi watched the battle scene between the Soul Eaters and the junior grim reapers.
