Those years when I was looking for my father in Yokohama

"Before that, tell me your name first!"

For a moment, Saiki Kusuo had the illusion that he was more important than the world in the eyes of the Demon King.

"I'm Saiki Kusuo." After the introduction with a wooden face, Saiki Kusuo ignored the weird and terrifying illusion and continued to urge.

"Quickly tell me why you want to destroy the world this time."

He obviously arranged everything for the Demon King, didn't he?Isn't it good to go on step by step?Well, why do you have to blacken it?

"Saiki Kusuo..." After repeating the name, the beautiful future demon king explained to him with satisfaction: "I don't want to destroy the world."

Saiki Kusuo glanced at the lifeless surroundings, and then looked at the Demon King: "Look around and say it again!"

There is no living thing around, okay!

The Demon King choked on his sharp rant.

"Okay, okay." The demon king seemed to give up resistance, lowered his head and said in a low voice, "Whether I have thought about destroying the world or not, as far as the result is concerned, I am indeed the culprit."

"I don't want to." The demon king repeated again, and then he covered his eyes and sighed: "But I really can't bear it anymore - it's so uncomfortable, so painful, I'm going crazy!"

"What the hell is going on?"

Thinking of the prophetic dream, he has been observing the recent situation of the devil, why didn't he find something wrong with the devil?

"My body is condensed by pure power." The demon king, who covered his eyes, suddenly changed the topic, and said in a low tone: "I don't know why I came to this world, and how I lost almost all of my power. Only The little bit of strength left is only enough for me to keep my body still."

"Can you understand? That sense of emptiness and emptiness that is extremely lacking in strength?" The demon king put down his hand, and his purple eyes looked at him hopefully: "I have been enduring this kind of pain, wanting to make up for this emptiness— — But no, no matter what, the recovered strength simply cannot make up for the daily consumed strength!"

"The difference between gaining and losing power is getting bigger and bigger, and I can only walk towards extinction step by step—"

Saiki Kusuo had never felt this way, and he could only keep silent when faced with the demon king's confession.

The fiery eyes of the alluring demon king gradually cooled down. He closed his eyes slightly and repeated again: "I didn't intend to destroy the world!"

"It's a pity that I didn't find my father during this journey, but I got to know many shining human beings, and got a lot of help and companionship from them—I didn't want to bring disaster to them, so I chose to die by myself."

Looking at the indifferent Demon King, Saiki Kusuo suddenly understood something.

"But I didn't expect that at the end of the depression, I fell into a deep sleep, but the instinct of not wanting to die turned me into an irrational body, recklessly harvesting human life, so as to survive..."

"... until I woke up, the world became like this."

The Demon King looked at him quietly: "Although it was not my intention, it is an indisputable fact that the world died because of me. If you want to kill me...you can do whatever you want."

Anyway, he couldn't find his father either.

There are no fathers in this world.

As for going to other worlds to find it—for him who does not have the power to travel through worlds, how easy is it?

The bigger possibility is that after he destroyed the world, stepped into the space tunnel again, got lost in it, and died after exhausting his strength.

That being the case, the appearance of Saiki Kusuo at this time is another kind of relief for him.

It is not shameful to die at the hands of the same clan.

Telepathy has no effect on the demon king at this time, and Saiki Kusuo, who doesn't know the demon king's mental journey at this time, fell into deep thought.

"This time it's because the strength can't be replenished—"

Saiki Kusuo stared at the Demon King sharply.

"But you didn't mention the reason before!"

The Demon King was a little confused by his incoherent words, so he heard Saiki Kusuo continue: "I took you away from Yokohama this time, and you destroyed the world because your power couldn't be replenished, but you were in Yokohama. Then there is no such trouble!"

Facing the stunned demon king, Saiki Kusuo made a conclusion: "This proves that compared to the peaceful Tokyo, the chaotic Yokohama is more suitable for your recovery. Yokohama has what you need!"

Having said all this, the Demon King has already reacted, showing a clear chuckle: "So that's the case, it's not the first time you've seen me."

As he said that, he seemed to grasp some hope, and his eyes on Saiki Kusuo became bright again: "Kusuo can travel through time, right?"

Without waiting for Saiki Kusuo to admit, he said to himself: "If you don't want the world to be destroyed, go back to the time when I first came to this world. Kill me who was weak at that time, and this future will no longer exist!"

The face is delicate and beautiful like a flower, and the charming devil smiles very beautifully.

But the words that came out of his mouth were terrifying and extremely vicious.

Saiki Kusuo was in a complicated mood: "...that's you too!"

Is the Demon King so mad that he won't even let his past self be spared? !

The Demon King just smiled, with a gentle tone, but with an undeniable momentum: "If you want to save the world, you have to listen to me, Kusuo."

"Only by the death of me in the past can you truly save this world."

"Otherwise, you can only see a future where the world is destroyed."

"After I control the whole world, you will no longer be able to travel through time."

"This future will become an established fact that cannot be changed—"

"I——will eventually destroy the world!"

The familiar words similar to those before made Saiki Kusuo breathless.

……

Saiki Kusuo returned to his timeline.

It was the morning after he sent the Demon Lord to the orphanage.

But the future he has just been to has told him the cruel fact that this still cannot save the world.

Thinking about the words of the future Demon King, Saiki Kusuo rarely felt grief and indignation.

[Did I owe you in my previous life! 】

So let the devil torture him like this for the rest of his life!

But no matter how sad and angry, Saiki Kusuo still took off the suppressor on his head——

【Time back】

***

One night more than three months ago——

After many adjustments, Saiki Kusuo finally measured the exact time when the Demon King came to this world.

Hiding in the dark, he saw with his own eyes that in a hidden alley in Yokohama at night, after a crack in space appeared and disappeared in midair, a purple-black flower that looked like a mandala slowly fell from the air. .

At the moment when it was about to fall to the ground, the delicate and mysterious flower turned into a human form——

It was a childish and delicate child, who looked about eleven or twelve years old by visual inspection.Wearing a large purple-black quaint robe, long black hair hangs down behind him.

The little boy slowly opened his eyes, revealing a pair of purple eyes full of bewilderment.

But this daze only appeared for a moment, and there was no trace of emotion on his face anymore.The emotionless purple eyes scanned the surroundings, and he walked out of the alley lightly as if he was weightless.

...he wasn't even wearing shoes.

【...Is it really a person from another world? 】

Seeing the erratic pace of the young demon king in front of him, who didn't show it on his face, but cried out weakly in his heart for discomfort and pain, Saiki Kusuo, who was still a little bit resentful, suddenly felt complicated.

【To kill someone or something, it’s better to kill an underage kid... Even if the devil king is not a human being, I am a human being! 】

Thinking of what the future Demon King said, Saiki Kusuo said that the concubine (crossed out) could not do it himself.

[Since you are not human, don't wear human skin.Wearing such a realistic human skin, isn't rounding it up just asking me to kill someone? 】

[I'm not a murderer, I'm not interested in killing people, thank you! 】

Having said all this, it was still a certain superpower who refused to admit the fact that he couldn't do anything to the Demon King.

[...It's not that I can't do it! 】

Thinking of this, Saiki Kusuo still kept his invisibility and chased after him.

Then, he witnessed a scene where the demon king seemed to be lured/abducted by someone, but in fact the other party was influenced by the demon king to become a tool man.

The Demon King who had just appeared in Yokohama was coaxed into a car by the old leader of the port mafia and taken away.

However, Saiki Kusuo clearly heard the voice of the Demon King who was relieved to have found a temporary asylum.

[It's really weak. 】

At a glance, he saw through the true face of the demon king who was trying his best to cover up at this time, a strong outsider but a dry man in the middle.

【... But I'm not used to shooting little ghosts. 】

Saiki Kusuo once again rejected the proposal of the future Demon King.

In the days that followed, Saiki Kusuo stared at the extremely weak Demon King with inexplicable and complicated emotions.

He saw with his own eyes how the young Demon King, who didn't understand anything at first and was crying out for pain and discomfort in his heart, endured the pain bit by bit and tried to relieve the pain with sleep——

【Yeah, I'm not your guardian, I won't love you】

Said something indifferent, but Saiki Kusuo stretched out his hand to frown on the bed, murmured about his father in his heart, and the young demon king, who was sleeping restlessly, quietly tucked in the quilt.

Then, at the moment when the Demon King suddenly woke up, he teleported back home.

……

Yokohama does have an existence that can restore the power of the young Demon King, that is, the dead breath in the mouth of the Demon King.Let Saiki Kusuo visibly see with the naked eye that the Demon King has recovered from the extreme weakness at the beginning to a state where he is still weak but not in danger of life.

He even had the energy to learn a strange language with the old leader, and then ordered the old leader to help him find someone.

Looking for a person with no exact name, unknown image, and abstract appearance—that is, the father of the devil.

【So you went to another world to find your father?What kind of script is this for little tadpoles to find their mother.But this father is really unreliable, he actually asked a kid to cross the world to find his father. 】

After making complaints about the unknown father of the Demon King, Saiki Kusuo began to think about the possibility of helping the Demon King find his father, reunite their father and son and leave this troubled world, so as to save the world.

[Obviously impossible! 】

[The future devil king has destroyed the world and he didn't see his father's shadow, so he probably isn't in this world at all]

Saiki Kusuo couldn't help feeling even more tired when he thought of the previous scene where the future demon king quietly waited for him to kill him.

[Why is the devil so difficult to serve?If the cake is gone, the world will be destroyed, if human beings are too ugly, the world will be destroyed, if there is not enough energy, the world will be destroyed... Will you destroy the world one day because you didn't find your father? ! ! 】

Thinking about the demon king who could destroy the world because of nonsense reasons such as not having a cake, Sai Mukusuoxiong did not doubt the possibility that the other party would destroy the world because he could not find his father.

——He is really a demon king made of iron, in a world of flowing water, he is right as a tool man.

【... Let's destroy this fragile world together with the Demon King! 】

Thinking of the end, Saiki Kusuo, who had been forced to be a tool man many times but was useless, finally couldn't help but want to kill this evil devil and this fragile world.

Come, let's die together!
