Iwasaki entered a voilet portal dungeon. The place was relatively isolated, so there were no people near that portal. Akira went inside too.
Iwasaki went directly to meet a person in the forest of the dungeon. That man had four subordinates with him. Upon laying his eyes on the man, Akira's heart pounded.
A mixture of rage, sadness, and also happiness for finding him so quickly made Akira anxious, and it jogged his memory. 'Your mission is to kill Haru Haruka, the fallen beauty.' That sentence resonated with Akira's thoughts continuously. As he remembered that man's old face, again and again, Akira's rage knew no bounds.
Ding
Akira received a system notification from the system but he couldn't care less. The man suddenly turned towards Akira, sensing his killing intent, but the man didn't find anything.
'I let my killing intent out. He must have noticed. Should I run?' At that moment, Akira suddenly realized. 'Why do I want to run?' He had been trying his best to hide his identity, but why was he even afraid to use a fake identity? Akira stood up with determination. 'There are only a few ways to change user names, but I know most of them. So why should I be afraid of even using a fake identity?'
They noticed Akira when he came out. "Is that Black Bear?" the boss man asked.
Iwasaki was shocked due to painc. 'Why is he here? Did he follow me? No, the boss will kill me at this rate.'
"I have wanted to meet you, Black Bear," the man in the black suit said with arrogance, as if he were someone above everyone else.
"So you are the one that sent a lackey to follow me. That was dangerous; I almost killed him when he followed my brother. You are the final boss of this group, right?" Akira took out needles into his fingers.
"Oh! Let's see your skill," said the man without any sort of fear in him, but Akira knew that was all a bluff. That man would never let his guard down, even when killing a real ant.
'Black Mamba, I must kill you today,' Akira thought while remembering the order to kill Haruka. It was Black Mamba who gave the order.
The four men rushed to kill Akira, but Akira skillfully threw the needles, which were attached with strings. They surrounded the four men due to his string control skill. Then he clenched his fist, cutting the four men into pieces in a matter of three seconds.
A system notification came, but Akira didn't pay attention. Black Mamba didn't flinch and clapped, impressed. "Nice string control there."
'Bastard, you are the one who taught me. You might find that in hell,' Akira thought as he walked towards him. Both of them were extremely patient and observant.
Black Mamba was the one who taught everything related to fighting and killing to Akira in the organization. The head of the Heavenly Snake organization was named Heavenly Snake.
Under him were his 15 direct subordinates, and only they knew who Heavenly Snake was. They all had names of snakes, and Black Mamba was one of them. Akira didn't know the amount of loyalty they had for their leader, but he guessed he was so powerful that they wouldn't dare to betray him.
These 15 subordinates were independent and could raise their own subordinates. Black Mamba specialized in raising subordinates through blackmail and hostage methods.
His favorite was Akira, although he couldn't make him his successor due to Akira's persistence in protecting a hero named Haru Haruka throughout his time in the organization. He raised him to be stronger than his successor.
No one actually knew how powerful Akira was; even Black Mamba lost track of Akira's strength at some point, and the only reason why he could still control Akira was due to Iwasaki's skill.
As Akira came three meters closer, suddenly Black Mamba threw needles and skillfully controlled the strong strings attached to them and wrapped Akira, but when he tried to tighten it, the strings became looser and fell down.
That still didn't flinch Black Mamba. He saw as Akira reached one meter closer and threw a needle with his right hand, but the deck of cards stopped it. That block sent wind ripples due to the speed, but there was not a scratch on the first card.
Black Mamba was already below Akira with a deck card between his left hand's two fingers, trying to slice Akira's stomach, but Akira was in no rush as he could see that move in slow motion.
He blocked it with a dagger that conveniently appeared in his right hand while swinging. At the same moment, Akira caught Black mamba's head with his left hand and pushed it to his raising knee while pushing away the dagger and card clash aside.
But that kick was stopped by a string barrier two inches in front of Black Mamba's face. Black Mamba threw another needle with his right-hand fingers, but the pack of deck stopped it again.
For Iwasaki, only afterimages were left to see. The wind ripples that came didn't match with the afterimages. At that moment, he understood what kind of monster he tried to mess with.
Akira already had a needle in his left hand, which was holding Black Mamba's head at that moment, and poked Black Mamba. After feeling that poke, Black Mamba stepped back and took out a potion trying to detoxicate himself, but Akira stopped attacking.
That surprised Black Mamba for the first time, but he still took the antidote.
*Cough*
Black Mamba felt incredible corrosion happening inside his body, and his body lost connection with his mind. He collapsed while he was still conscious. Why wouldn't Akira know his outdated antidotes after 14 years?
Iwasaki was terrified to see Black Mamba, a terrifying man, just collapse in a matter of seconds. A sword appeared in Akira's hands, and he pierced it into Black Mamba's head and got completely relaxed.
Iwasaki's body moved on its own to run away feeling that Akira might ignore him for a few seconds. Akira slowly turned his head while taking out one card from the deck. His hand slowly moved like throwing while his palm was 90 degrees.
In the end, he would flip his palm at incredible speed, which would send the card at high speed and pierce Iwasaki, but suddenly Iwasaki got stabbed by a sword in the heart.
Looking at that, Akira lost grip of the card. Before the card fell down, he reached there and sliced Iwasaki's head before he died. Akira caught the head and used a lot of power to make the head into a liquid state.
Haruka lost the grip of the sword due to the fear of murder. Akira caught her arms and yelled, "No, I killed him." Then he hugged her, but she couldn't process it after that.
'It's too late to say that,' he thought and said, "He is a big criminal. He ruined many lives in my nightmare. You did a good thing." He patted her head while using detection to see if anyone was around. He got relaxed after not sensing anyone.
"He is a monster, no need to feel bad for killing him," he said softly.
*Ding*
A system notification came, and Akira saw it while still holding Haruka. She was silently shedding tears without letting out a sound.
She was not crying because of the guilt she was feeling at the moment but because Akira must have gone through more than that. She blamed herself for being so ignorant all this time, for not realizing the depth of his struggles.
The reason why he became so selfish, the reason why he kept insisting on keeping their identity secret and getting strong as soon as possible, must have been significant.
She wasted her time thinking about something totally useless while letting him suffer alone, she couldn't forgive herself at that moment.
Yes, she didn't like killing people, but once she saw Akira do it, she decided to take the same path. Getting closer to Akira was her natural instinct, and to do that, she naturally thought she should follow his lead.
**Error
You killed Black Mamba. You completed the quest.
Reward: All items in Black Mamba's and his lackeys' inventory and their coins.**
Akira was shocked and confused by that message. There was no such thing as a quest in this system. That was the first time he encountered it. 'Inventory materials can never be taken by a second person no matter what. Just what is this error message?
There is only one possibility. This locket is the only item that can't be kept in inventory. Maybe this is the cause of the bugs I am getting, but now it gave me a quest. Is it helping me to take revenge? It even improved my inventory space to fit all the items.'
**Error
You caught a Munarilla. You can place this in a human's ear to make them players.
Warning: There is a high chance of getting investigated by operators. Strongly advised to let it go.**
Generally, all panels would be in blue, but this panel was in red. 'What?' Akira looked at his left palm. Although his hands were red with blood, there was something red moving.
'This... did I get it from Iwasaki's head? What if this is the reason why everyone was able to awaken the system? And operators, who are they? Hey, can you hear me, error message?' There was no response. Akira threw that thing away.
Although he was motivated to give it to his parents, whoever these operators were, they must not be from Earth. If they could create such a thing, he would be no match for them.
At that moment, he only had one goal in mind: to calm Haruka.
