Fight or Flight

Yurina, whose arm was covered in blood from slicing the young adult, turned her head, slowly, but distressed toward Satoya and Sendo. Her eyes were lifeless, as if she had given up on, face freshly covered in blood, a sign that she already killed more than it seemed. She was also shot multiple times, signified by the bullet holes with blood still soaking the fabric of the lab coat, even soaking the . 

"Satoya, do you know her?" Sendo asked urgently, as he was quick to notice Satoya's face of pure shock. Before Satoya answered reluctantly, Yurina lunged toward Satoya in a savage, almost barbaric manner. Sendo shoved Satoya to the side before clashing with her, "this strength is not natural..Is this the use of some kind of drug?" Sendo contemplated, although Sendo wasn't inherently struggling on focusing on Yurina, he was more so focused on Satoya. 

Yurina then kicked Sendo back, before she swung her sword at Satoya. Satoya barely managed to block the slash, but was nearly crushed against the wall from the sheer force of the blow. "Just run, please." Yurina thought, pleading with Satoya, and Sendo to free herself, or atleast end her suffering. 

Back then, shortly after Yurina officially became "Roland's first assistant," Roland knew she'll inevitably rebel in the future, so he created a drug that increases her adrenaline, and forces her instincts to take "fight or flight" responses, except it forces her to fight until she dies, still consciously witnessing everything she done, while also feeling the pain of every injury or wound she is inflicted with. 

The drug that Roland injected her with just recently took effect, but coincidentally, she was found by a group of soldiers and armed young adults. This led to her, without any control on what she was doing, while also feeling every pain she was inflicted, to massacre the group of people. 

Sendo while Yurina was focusing on Satoya, held his sword back, before he channeled a light violet flame with electricity emitting from it (plasma), then thrusted his sword from the distance toward her, sending a precise blast of plasma. 

Yurina maneuvered in a flexible, nearly inhuman way around the plasma blast, then charged toward Sendo instead. Satoya, despite being attacked by her, his mind was full of concern, questions emerged in his thought process, "what happened to her?" "Why is she fighting like this?" "What did Roland do to her?" 

Sendo's calling woke Satoya up from his deep moment of thought. His voice, demanding answers, asked Satoya, "who is she?" As Sendo and Yurina fought, "the way you reacted to her implies you know her!" Sendo continued, with him holding back, blocking every unnatural attack from Yurina, who started weeping, even though her face was locked in a state of distress. 

"Her name is Yurina," Satoya said, he was still thinking of the possibilities of the atrocities or drug Roland might've given her, but most importantly, "is there any way to help her?" Sendo continued to clash with Yurina, the two exchanging blows, Sendo was obviously stronger by a mile, but he was holding back, he needed to know if she was important to Satoya, and if he needed to hold back or not. 

"I don't know her completely, but she is a forced assistant of Roland." Satoya added on, his voice was helpless and frustrated. Sendo felt the burden of the situation, but his mind remained calm. He had to incapacitate her, even if she'll end up suffering in pain from it, and he couldn't come up with any other possible solution, even if they both ran, her unnatural and inhuman speed (boosted by adrenaline) would mean she'll catch up to them.

Satoya held up his sword, but Sendo held his arm out, "I know you're trying to save her, but thinking too long might get you killed.." Sendo said, assuring him that he'll handle it before Sendo went into a stance, then engulfed his katana's blade with light violet plasma. 

"Unlike Ludwig, I'll spare her, but I might need to incapacitate her." Sendo said, before he looked back toward Satoya, making sure he understood what he meant with him nodding his head slowly. 

"Since she is right hand dominant, and the way she is fighting.." Sendo thought deeply, before he lunged past her, cleaving her right side and arm in a crescent shape, with the plasma crackling in the air like fireworks, "that means I can spare her while also leaving her incapacitated till the drug wears off while also making sure she won't be a major threat in the meantime." Sendo thought as he turned back toward Yurina who fell on the ground. There wasn't an enormous amount of blood, as Sendo covered his blade with blazing plasma, essentially cauterizing the wound.
