My System: An Evolved Computer I Made With My Unique Ability—

Midori's little sister, Miya, had always been sickly ever since she first came to this world. And of course, it didn't help that they were poor and the only thing they could do was look after her with great care since they couldn't afford hospital bills. And it's not like Miya was terminally ill, she just has a weak constitution so she easily gets sick. Because of that, it's quite a normal occurrence when she gets sick.

But today out of all days, Midori could tell that Miya was more ill than she used to be. He immediately rushed towards her side and grabbed her by her hand, ignoring the crowd that surrounded her. "Miya, what are you doing? Hang tight the ambulance is over here."

With a weak nod, Miya forcefully smiled towards her brother, her eyes fluttering. Even though she's still on the verge of death, Midori could tell that she was trying to fight whatever it is that's destroying her body. But even then, her hand already felt lifeless and cold, making Midori bawl his eyes out.

"Son, we've called the ambulance two minutes ago. But at this rate... I don't think they'll be able to arrive in time. We didn't know what happened to her, she just suddenly collapsed and coughed up blood." Their dad said, his eyes still swollen from all the tears he shed.

When Midori had the time to look around, he tried to analyze if something really went wrong, or maybe she had probably eaten something bad and it was more than enough to put her in a critical state. That was explainable. However, based on everyone's expression, they really did not know what happened to her. Midori felt bad for raising his suspicions on his family members but he couldn't help it. After all, Miya wouldn't get sick that quickly unless something really happened. Now he knows that something really did happen but it wasn't connected to anyone in the room. It was just an unknown accident... or probably a premeditated one but the culprit is yet to be identified.

"Big brothe— cough!" Miya weakly uttered with a pained expression on her face, coughing up blood in the process. But this time, the blood wasn't a nice red color. Instead, it had the color and appearance of black tar and its viscosity was different from that of blood since it was more syrupy. Midori's pupils dilated as he patted his sister on the head while leaning in to hear her better. He was perfectly aware that the best thing he could do right now was tell her to save her energy and stop talking but seeing that she was trying hard to tell her something, he just couldn't do it. By now, everyone was already bawling their eyes out since they could already foresee her dying. At most, she only has a few seconds to live.

"What is it? Come on, Miya, you can say anything to your big brother." Midori's eyes welled up with tears but he tried not to show a weak side to his sister so he suppressed his tears. That didn't stop it from falling though since a split second later, two rivers of tears were already streaming down his cheeks and snot was falling from his nose.

"P...poison... I... take care of... i love you all, big br— " Miya said as a single tear fell out of her eyes.

Midori could've sworn that he heard the steady beep of the heart rate monitor as it signaled the loss of detected heartbeat. A scream echoed throughout the room as Midori grabbed his sister by her head and bawled his eyes out. Everything flashed before his eyes as he clearly remembered when his youngest sister was born. Because most of the time, he would look after his sister when his parents aren't at home. Whenever she was sick, the first name she'd utter was that of Midori's name and for sure, Midori would run to her aid and take care of her, cook food for her, and watch over her until she feels better.

And yet now... Midori was too late. He could imagine his younger sister calling out to her and yet he was nowhere to be found since he was at school. He couldn't even take care of her in her last moments on earth. And by the time he arrived, she was in no condition to talk. Midori continued screaming while clutching the lifeless body of his sister. For the first time in his life, Midori was in an uncontrollable berserker state, and yet he wasn't rampaging. He was just angry and grieving, not even moving a muscle even though his body forcefully told him to run amok and destroy everything in his path. In a matter of seconds, his body grew thrice his size, and yet he was still holding his sister as gently as a mother elephant caressing her newborn calf.

But just when he was about to lose himself, something in his brain clicked and his vision changed drastically. Instead of seeing everyone normally, he perceived everyone as if everything in their body was see-through. If he wanted to look at the muscles, then he could see it, if he wanted to look a little deeper, he'd be able to see the bones of everyone in the room. And it didn't stop there, he could even see the nerves and their electric signals that travel to the brain.

No sooner had he looked towards his sister, did he see that something was wrong within her body. Somehow, some sort of black tar was filling up her lungs, blocking her breathing and scraping her lungs every time she breathed. It looked worse compared to how it is viewed outside and he couldn't help but hold his breath. And he also found out that...

... his youngest sister was still alive. The only reason why she was limp and lifeless-like was that she suddenly fell unconscious— a normal response by the body when someone's having difficulty breathing. This response has even made a person drowning survive since the body would actually slow down the breathing just enough to keep the brain alive. Even if it was slow and the heartbeat was close to being undetectable, the person is still alive.

Midori wanted to sigh in relief but he knew that his younger sister is still not out of danger, not until that dangerous substance was removed from her system. Without thinking too much about it, Midori focused on her lungs and tried to see what the root cause of the problem was. That's when he noticed that his hands were glowing a weird greenish color which encompassed his younger sister's chest area. Little by little, the mysterious liquid in her lungs started to dissipate. It was slow and Midori couldn't bear to watch as his glowing hands did its wonder. At that point in time, he wasn't even thinking that he just discovered his other superpower. All that was in his mind right now was that he had to save his sister no matter what.

With another ear-piercing scream, Midori's glowing hands shone brighter until it almost filled the room. He focused on getting rid of the dark liquid in his sister's lungs then after that, he started repairing the bleeding in her lungs and the scratches the liquid caused on it. The longer the time passed, the stronger his healing power got and somehow, he wasn't the least bit exhausted. In fact, he felt more energized before that he continued healing and healing her sister until she was rid of every ailment and her weak constitution.

By then, Midori had already lost his mind and no one can stop him. He was just screaming and letting his healing powers run wild. It was obvious that he was using his berserker superpower along with her healing and that made him an unstoppable healing machine. His parents and siblings, who've been watching the entire thing, panicked as they tried to stop them as they could. But of course, they knew that no one in their family had the ability to stop Midori from rampaging... and also, if they were to attack him, it might unnecessarily cause Midori's anger to be directed at whoever did it. That's why the entire family couldn't do a thing as they painfully watch the entire process.

Pretty soon, however, the ambulance came, and in came the Nurse who was on duty that day. The moment he saw what was happening in the house, she immediately fired a soft light beam which interrupted Midori's energy flow and it temporarily stopped him from what he was doing. In that instance, Midori got back to his senses and realized that he had gone to berserker mode once again. This time, however, no one got hurt, instead, the result was the direct opposite of what he was expecting.

"Big brother... it's okay, I'm already fi— big brother? BIG BROTHER!!!" Miya turned from being gentle to panicking as her older brother slipped into unconsciousness and collapsed right in front of her.

For a change, Miya wasn't the one admitted to the hospital that day. Instead, it was his brother who got admitted and as an icing on the cake, it was actually his first time being admitted to the hospital.
