Midori continued to run away from the motel, but she suddenly stopped to run.
"It's not like they'll pursue me anyway" thought the green haired girl, while walking.
She hesitated, something was bothering her about what she did. Midori tried to ignore this unpleasant thought.
"I won't go back to save her, Takechi-san can die, I don't care about her!"
The green haired girl suddenly stopped walking. She was in front of a park. Still confused about what happened, she sat on a bench to think. She took off a flask from her jacket. It was another antidote.
"I don't have this second antidote to save her anyway, that wasn't what I had planned, I don't have to save her…"
According to Midori's plan, she was only supposed to use Shiena as bait to lure Otoya. The serial killer was her target since the beginning, Midori never had the intention to let the brunette die. She was sure that Otoya would use the antidote for herself. When she gave the flask to the serial killer, the green haired girl was ready to shoot her if she took the antidote. She had her gun behind her back, ready to kill Otoya by surprised. Midori had planned to give the second antidote to Shiena, because she couldn't let the brunette die.
"This teacher, Kamikuro or something like that, she didn't want Shiena-san to die, she would kill me if I kill her. I already have Yukarin's assassins after me, no need for another person after my life"
Midori never had the intention to give the second antidote to Otoya if she decided to save Shiena, because she was sure that the serial killer would never sacrifice herself for another person. The green haired girl wanted to see Otoya's true self before killing her, she wanted to see how this monster could be selfish. It was a true shock for her that Otoya gave the antidote to Shiena, she didn't expect this at all.
"I don't have to give her the other antidote, because I didn't even plan to give her in the first place! She deserve to die, why am I feeling like I was the bad person in this story? Dammit, why should I save Takechi-san, I hate that girl!"
What did she say? She hated Otoya? Since when Midori is able to know what feeling she had toward someone else?
"I hate Takechi-san…yes, I'm sure, I truly hate her! This is the first time that I'm sure of what I feel. Then, it's normal to let someone you hate to die, I did nothing wrong!"
"Nothing wrong? You are about to let die someone who sacrificed her own life for the one she loved, even if you can save her life. You always say that Takechi Otoya is a monster because she caused pain to the people who loved her victims, but this is exactly what you're doing to Shiena-san!"
Again this voice into her head, probably her conscience or something like that. Midori couldn't accept this guiltiness, she refused to acknowledge that what she did was wrong. She fell from the bench on her knees, putting her head between her hands, desperate and totally confused.
"This isn't me the monster, this is Takechi-san! She killed plenty of innocent people, me I only killed bad people. Takechi-san isn't innocent, I don't have to spare her life!" shouted Midori.
"Since she's with Shiena-san, Takechi-san only killed one person, and it was to protect Shiena-san. If she didn't kill anymore, what's the point of killing her? It would only bring pain to Shiena-san"
Midori suddenly rose up and violently kick a rocked that was on the ground in a fit of rage.
"Dammit, I hate you Takechi Otoya, I hate you so much!" screamed the green haired girl. "I let some of my things at the motel's room, I should go back anyway, so maybe I can give her the second antidote when I'll be there. Maybe."
Midori began to walk, heading to the motel. She suddenly began to run.
"I should hurry, otherwise it would be too late!"
When Shiena regained her body's control, she approached from Otoya, who was agonizing on the bed. The serial killer felt like her arm was in fire. That was an unbearable pain, but she forced herself for not screaming, because she didn't want to make Shiena feel guilty.
"Otoya…why? You'll die, why did you save me?"
The serial killer, despite the pain, found the will to smile to her girlfriend.
"Because, otherwise, you would be the one who died, and I can't allow this"
Tears began to roll down on Shiena's cheeks, when Otoya's eyes became wet.
"Please Shiena, don't cry. Otherwise, I'll also…" said Otoya, before crying.
They both cried. The brunette cried because her loved one was dying, while Otoya was crying because she was devastated to see the sadness on Shiena's face. Suddenly, she grabbed Shiena's waist with her valid arm and hugged her.
"I know that it's a selfish request, that I have no right to ask this, but can you stay with me until the end?" asked Otoya. "It would be less painful if I can feel you by my side, Shiena"
The brunette didn't want to see Otoya die, but she couldn't refuse her dying wish. She pressed her forehead on Otoya's forehead, trying to suppress her sob.
"I love you, Shiena…"
The serial killer suddenly closed her eyes, while her limbs became weak. Shiena was scared, she thought that Otoya was dead.
"No, don't die, don't leave me, Otoya!" cried the brunette.
Shiena noticed that she was still breathing. Otoya was only unconscious, she was still alive, but not for long. The brunette didn't want to accept this fatality, she didn't want to let her girlfriend die without trying at least something to save her life. Shiena spotted a piece of string on the nightstand and had an idea. She took the string and tied it around Otoya's arm, the one that was poisoned. Shiena tied the string over the place where Otoya receive the poison. She tightened it enough to stop the bloodstream into the serial killer's arm, stopping the poison's spread into her body.
"I love you too, Otoya, and this is why I won't let you die!"
Otoya woke up, noticed the string around her arm.
"Shiena, what are you doing…?"
"There have other way to get rid of poison, not only an antidote"
The brunette noticed the knife that Midori forgot and took it.
"If I make you bleed enough, I could evacuate all the poison inside of you" said Shiena.
The brunette approached the blade from Otoya's arm. Her hand was shaking, to intentionally hurt her girlfriend, even if it was to save her life, was stressing for Shiena. Suddenly, Otoya gently grabbed Shiena's shaking hand.
"Please, do it. I don't care if it hurts, it can't be worse than now" said Otoya.
Encouraged by Otoya, Shiena pressed the knife where the syringe was stung. The brunette made a deep incision on Otoya's arm. A lot of blood came out. The serial killer rose up from the bed, letting her blood running down her arm, creating a blood's pond on the floor. The blood loss was too important, Otoya began to feel terribly dizzy. Shiena caught her before that she fall on the floor.
"How long…should I let my arm bleed?" asked weakly the serial killer.
"Until you don't feel burn sensations anymore" answered Shiena.
With her uninjured arm, Otoya hugged once again the brunette.
"Thank you, Shiena"
"Oh, I forgot that there were homemade ways to get rid of poison" said a familiar voice.
Shiena, still holding Otoya, turned back and saw Midori into the doorframe. The brunette couldn't find any word to express the rage she had toward the green haired girl.
"Well, since you don't seem to need help, I'll just go. Sorry for the bother" said Midori, before leaving the motel's room.
Shiena laid her girlfriend on a chair and took the knife.
"When you won't feel the burning sensation, stop the bleeding" ordered the brunette, before pursuing Midori.
The green haired girl climbed on the motel's roof, waiting for Shiena. She didn't have to run away, she was the one with the most dangerous weapon between them. The brunette joined her on the roof, holding the knife. She gave a furious gave to Midori, showing an urge to kill.
"This is the first time that I see you with such a murderous gaze, Shiena-san"
The brunette didn't pay attention to Midori's provocation and approached from her, with the intention the stab the green haired girl. Midori took out her gun and forced Shiena to stay back.
"Stay away, or I'll shoot you" menaced Midori.
Shiena didn't listen and continued to head toward the green haired girl. Midori began to panic. She was expecting that the brunette would be scared and leave, but it wasn't the case. Shiena suddenly began to run, while pointing her knife. She was so angry that she didn't feel any fear, and she also knew that Midori was a terrible shooter. Midori began to recoil. She didn't know what to do, everything was too quickly. Shiena tried to strike Midori with the knife. The green haired girl recoiled too much, she was already at the roof's limit. She lost her balance and fell from the motel, before crashing on the ground. Fortunately for her, the motel only had one floor, the fall wasn't mortal. Midori stay on the ground, unable to move. Shiena headed to the staircase, she still had the intention to kill. Midori hardly rose up and began to limp. She walked along the wall to support herself. In her hand she had the flask, that wasn't broken. She felt a sharp pain into her leg and fell on the ground. The antidote rolled near her. She realised too late that she lost her gun.
"Stay where you are, Sasoriza!"
Shiena was holding Midori's gun. She had the green haired girl at gun point, ready to shoot her.
"Let me tell you a secret, Shiena-san. I'm no longer a member of Collective Dismissal, so you won't have any problem with Yukarin if you kill me"
"Why are you saying me this?"
The green haired girl began to smirk.
"To be sure that you won't hesitate to pull the trigger. I prefer to be killed by you, by your own will, rather than by one of Yukarin's puppet" answered Midori.
Shiena approached from Midori and pressed the gun on her forehead.
"I'll kill you because of what you did to Otoya. Not only today, also for the torture that you have done to her! I don't care if you betrayed our group, what you have done is unforgivable!"
While Shiena was ready to kill Midori, the brunette noticed the antidote on the ground. The flask was still not broke. A doubt appeared into Shiena's mind. Why Midori came back to the motel? It was quite stupid. She should have a reason, the green haired girl wasn't stupid enough to come back for nothing, in view of the danger.
"You had…two antidotes? Why did you came back Sasoriza, what was your purpose!?"
Midori couldn't tell the truth to Shiena, that she came back in order to save the serial killer. She preferred to die than admit it, it would be like admitting that she was wrong, and her pride couldn't take it.
"It doesn't matter anymore, just pull the trigger Shiena-san. I tortured and almost killed your girlfriend, why are you hesitating? What are you waiting for? You want me to beg? Then, please, finish the job quickly, you coward!"
"To kill or not to kill, that is the question" (citation from Fire Lord 626).
I'll be busy for the rest of the week, so next chapter will be only next Monday, sorry if I let you on a huge cliffhanger (well, I already told you, I'm a sadist)
The real question is: What Shiena's teacher has to do with this story?
