Ultimate System Creator

"I'm bored. Even after becoming the inheritor, I didn't feel entertained but empty inside."

Keith muttered as he looked at the picture of a certain pink-haired yandere girl that he cared about so much.

"If you were still alive, I wouldn't be this bored. I wouldn't feel empty, as your love made me feel whole."

"Even when I killed you, I hate to admit it but I regret it. I, who swore that I would never regret anything, regretted that I had killed you. How ironic."

"But…"

Letting out a soft mutter filled with exhaustion, Keith gazed at the world, which was soon coming to an end. The sun had already become a black hole and was several minutes away from devouring planet earth.

"If I hadn't killed you, wouldn't you have killed me?"

Thinking about his girlfriend's twisted personality, Keith couldn't help but let out a sigh.

"After all, I had killed your sister. She was your only family, yet I took it away from you."

"But deep down inside, I know you love me and you also know that I love you. Even if others deem our relationship as toxic, I always say that's just what we are. And that's what makes us Keith McDowell and Sherry Blossom."

After dealing with all of the shitty people who went against him and his girlfriend, Keith no longer cared about their opinion.

Caressing the photo of his girlfriend, Keith reminisced about his memories with her.

"I know that even if you had killed me, you would have done that because you loved both me and your sister. I know that after you killed me, you would kill yourself afterward."

"After all, what's the point of living when all those who are dear to us, could no longer accompany us in our life?"

Keith allowed himself to fall on the ground, and his back landed on the ground. Laying his body on the hard rocky surface, he looked up at the sky that was currently being devoured by a shade of black.

"Only when you lost something dear to you, will you yearn to obtain it again?"

He donned a smile that was devoid of any emotions but it emphasized the emptiness he felt inside his heart.

"I remember the time that you kept on saying that I'm a know-it-all."

"Well, I admit that you are right. I had indeed known that this would be the outcome after I killed you. I knew the consequences of my actions yet I still did it."

"I sacrificed you just for a book."

Holding the brown-colored book in his left hand, Keith opened it and bit his thumb.

Golden-colored blood oozed out from his right thumb and he used his blood as an ink to write on the End Note.

"I'm bored. I might as well end this timeline and achieve a timeline where it is as chaotic as possible."

"When there is chaos, unpredictability follows. And only when a know-it-all like me can prevent myself from predicting the future, would it be more entertaining."

"Others fear the unknown. But I seek it as my entertainment to uncover it!"

While Keith muttered that to himself, his surroundings disappeared in an instant.

Anything, whether it was planet earth or the black hole in outer space, had ceased to exist. Every existence within Keith's universe had ended aside from himself and another entity.

A teenager wearing a tattered black cloak with black chains hanging on it appeared in front of Keith McDowell. The two of them were currently in the realm of nothingness, and the scenery was filled with nothing but the color of emptiness.

Afterward, the teenager kneeled on one knee toward Keith. Lifting his head, his brown-colored hair fluttered as his brown-colored eyes showed reverence and worship towards Keith.

"My lord, will you continue the cycle?"

In response to the brown-haired teenager's answer, Keith shook his head.

"No, Ende. After resetting the timeline countless times, I found out that the end is inevitable."

"After becoming the Universal God Of Insurmountable End, I found out that everything that happened in the past was within my control."

"After all, I created the End Note. I am the Universal God Of Insurmountable Doom."

Emptiness filled Keith's existence, as he found out that he was only delaying the end, but not preventing it.

He didn't expect that after he reached the Final Stage of End Note, he awakened his memories that he had sealed every timeline reset.

The End Note, which caused the entire universe to fight to the death for it, was his own creation.

And the so-called Universal God Of Insurmountable End was just his former identity.

"Ende, how many timelines did I become the Universal God Of Insurmountable End."

Keith asked his most trusted servant.

Ende, the servant of End, immediately answered his lord's question.

"Including the first timeline where this all began, at least 1,053,069th times."

Hearing Ende's answer, Keith sighed.

"How about the timeline when Sherry became the Universal God Of Insurmountable End?"

"It had never occurred, my lord. In every timeline, you manage to successfully kill her to reach this outcome. Not once did you lose your qualification as the Universal God Of Insurmountable End."

Receiving Ende's reply, Keith no longer hesitated.

"Ende, make sure that in the next timeline, Sherry becomes the Universal God Of Insurmountable End. The only way to break this cycle is to reach that outcome."

"It just so happens that I made a deal with Lord Zenchi to allow him to influence my universe."

"Just follow the usual plan but with minor changes. I will let you keep your memories while I will no longer seal mine but erase it entirely."

Ende frowned after hearing his lord's words.

"My lord, please think this through! Can you trust the entire universe to that woman? What if she betrays you after becoming the owner of this universe?"

Keith scoffed at his servant's questioning as he decided to answer his servant's doubts.

"You retained all of your memories for every timeline, right? Since when did Sherry ever betray me?"

"In fact, I betrayed her too many times, and not once did she betray me. I am a failure as her husband."

"Fortunately, I have already found the end to this vicious cycle. I no longer need to make her suffer for my sake."

With no hesitation, Keith wrote his final words on the End Note.

Afterward, Keith's existence disappeared and the only thing that remained was Ende and Keith's End Note.

Picking up Keith's End Note, Ende opened it and read his lord's final words.

[Everything listed on this End Note will END]

[1. The original timeline.]

[2. Keith McDowell's memories and qualifications of becoming the Universal God Of Insurmountable End.]

[3. The possibility that Sherry will NOT become the Universal God Of Insurmountable End.]

[4. The possibility that Sherry will NOT become a regressor with all memories of this timeline.]

[5. The code 0 protection mechanism of the universe.]

After reading it, veins bulged on Ende's face.

"Seriously? You want the protection mechanism of the universe against anomalies to end?"

"Bruh, my lord is too irresponsible!"

Although Ende complained, he continued his job as he fragmented the Final Stage End Note into several First Stage End Notes.

The realm of nothingness was being filled with space, time, and other concepts and creations until the universe reverted to normal.

"Sigh, time to fulfill my lord's orders."
