As soon as this strange voice starts to talk Yuu loses the control of his body. It is strange but even though his body moves it doesn't follow his will. What he doesn't notice are the changes of his body and his aura. His purple eyes change its colour. The purple of his eyes turn as reed as blood and the white of his eyes turn black. Around his body a a dark layer appears, that looks like his body is producing and can't keep it in. The last visible thing that changes is his hair. His black hair loses its colour and turns as white as snow.
The pressure he gives off draws the attention of every ninja present. The attacking group stops to laugh and is surprised. "Isn't that the kid? The description said purple eyes, black hair and around 4-5 years old... but the old man told us that he has a special ability to control shadows. That strange aura could be what he meant, right?" As he said that the other men agree with him, but are not sure what to do.
Before someone can do anything Yuu's body moves different from before. It doesn't move forwards or sideways, it is going down. He isn't falling down, his body is going through the ground. His body disappears in his own shadow. As his body is gone everyone is shocked, especially the enemy sensor ninja. "What did he do? I couldn't sense his chakra as he disappeared! Where did he go?" As he turns around he suddenly goes silent.
Yuu jumped out of the man's shadow and thrusts his arms out. He pushes a completely black blade through the throat of the man. Before he can react the life in his eyes extinguish. Everyone is silent. The only sound is inside Yuu's head. [Host killed ???. Host gained 35 experience points. Host successfully used an advanced technique of 'shadow unification' and used it in battle. Your proficiency of 'shadow unification' gained 50 points. 'shadow unification' reached level 2. As your bloodline limit reached the next level your capacity of absorbed shadows increased by 5. You can now absorb 5 shadows]
Yuu can hear the system, but he is frustrated because he can't kill them himself. He can see everything that is happening but he can't feel his body. It is like he is sealed in his mind while someone else controls his body. Either way, he has to use his new acquired shadow to support his body or he will die. While Yuu is alone in his mind, deciding what to do, his body is still fighting against the four men.
After he killed the sensor ninja the other men, that were cought off guard before, are taking a battle stance and one of them is dashing towards him. A voice sounds in his head and Yuu's body starts to grin. A second black item comes out of the ground and lands in his hand. While the man is dashing towards him he throws the shadow kunai and sinks into his own shadow again.
While the man evades the kunai, which disintegrates as it touches the ground, he hears a wretched scream. He turns around and sees one of his comrades with a bleeding shoulder, while the other lies motionless in a pool of blood. As he looks around he can't find the boy and the other ninja of the hidden mist disappeared too. All he can see is the silhouette of the three ninja.
As he looks around he sees something moving next to him. As he turns his body to face it his vision on his left eye turns dark and he can feel enormous pain. He falls down and screams: "Please stop! We will leave you alone, so please stop!" Tears run down his face as he starts to think about his brother. "I have a family so please let me live so i can see them again!"
He holds his hand above his bleeding, blinded eye and looks up. In front of him is the boy he was tasked to capture. A kid that completely eradicated his whole squad. As he looks the kid in the eyes a cold feeling spreads in him. He can't see even a glint of mercy on the face of this child. "Plea-" Just as he was about to beg for his life again the boy thrusts his blade trough the other eye. This time it goes so deep it cuts trough parts of the brain.
The last living member would be the man with the bleeding shoulder but he already lost consciousness from the shock. If he doesn't wake up he will bleed out in less than half an hour. After this massacre Yuu finally gets back the control of hos body. To his surprise everything he can feel is extreme pain. His whole body hurts.
All he can see before the system alerts him are a few figures coming towards him from the direction the enemies came from. He can't tell who they are because before they get close the system tells him [Host has forcefully used an ability of his bloodline limit that his body can't handle yet. Host's control of his bloodline limit isn't high enough to use this ability yet. That is the reason for the oain host is feeling right now. To save host's organs from damage the system will shut host's body down] As the system finishes it's sentence everything goes dark.
