Overluck MC

Sai closed his eyes and when he opened them, he saw that he was at the bottom of the ocean. He wasn't teleported to another place. He just went inside his mind.

There he can hear whispers.

"Steal." "Deprive." "Destroy." "Vengeance." "Take it all." "Show no mercy." "Kill them all."

Those are whispers of repulsive impulses. But those are not from him, they are from the evils he absorbed during his childhood until 'end', as for why and how he did it is another story.

After looking around for a while, he saw two white silhouettes.

"Umu. So, you two are souls used to repair mine, no? Since I dive in the very depths of Abyss, my body is destroyed and only my soul is left. Normally, I should have been destroyed but my soul managed to exist, but that doesn't mean it is perfect condition. My soul should be damaged very badly. And when someone dragged my soul out, they used the two of you. Well, that answers how I ended up on Earth. Anyways, I don't have any ounce of gratitude or anything since I was reincarnated out of my will." Sai walked pass the two silhouette and headed to the deeper levels of the ocean.

Suddenly, the two white silhouettes started a cyclone. A white crystal appeared between them and the three of them fused. A bright light is produced by the fusion. When the light dissipated, another Sai appeared. Unlike the original Sai, this Sai has white hair and red eyes. His school uniform is white and blue in contrast to the original Sai's black and red.

Even with that commotion, Sai still continues to walk, ignoring the White Sai.

White Sai realizing this, sprinted to Original Sai's direction with haste. He conjured a white broadsword and attempts to slash Original Sai's head.

Original Sai, who knew White Sai's attack through his Flawless Skill disappears before the sword reaches him.

"What?!" White Sai is shocked with what happened.

Original Sai appeared behind White Sai placing his left hand at White Sai's left shoulder leaving his left hand's index finger directed upwards. When White Sai look at the Original Sai at his back, his left cheek was poked by the index finger.

"It's dangerous for you to swing that sword at someone's neck, you know." (Original Sai)

"Quit mocking me!" White Sai said in anger as he attempts to cut Sai's head once again, which failed again.

"Whoa." Original Sai dodged that slash and appeared 3 meters away from White Sai.

"Ah, I see. So that's how it is. You fused yourself with my Superego and managed to keep a separate consciousness of your own, huh. Since you took the initiative to fuse yourself, I was able to know who you are. A composite being of Ruggiero and Sigurd, right? And your motive this time is to make sure I will not be able to gain back my inhumanity." Original Sai speaks as he smirks at White Sai.

"You are wrong." (White Sai)

"Huh?" (Original Sai)

"We do not intend to stop you. Our aim is to replace you." (White Sai)

"Eh?" (Original Sai)

"You are someone who killed all living beings and destroyed world once. In addition to your chaotic state of mind, it is possible for you to do it again." (White Sai)

"Wait a minute. Can we just solve this through discussion just like how civilized people do things?" (Original Sai)

White Sai did not listen to Original Sai and disappeared. He appeared in front of Sai suddenly while in an offensive stance.

"Oh crap!" It was too late for him and White Sai quickly stabbed him in his c.h.e.s.t.

"Guh…!" Original Sai vomited blood.

"This time, we will seal ourselves and will never risk the world of our power." (White Sai)

After confirming Original Sai's death, White Sai draws his sword but his hand was grabbed by Original Sai.

"Just kidding~! Do you really think that I was killed by a mere parasite that is leeching on my Superego?"

"Impossible?!"

"It's not impossible. I got Ego and Id on my side. Even if you got my Superego, this still my mind, my territory."

"Tch!" White Sai forces to get away from Original Sai but Original Sai's grip was too strong.

"Want to run away? No way. You wanted to replace me, right? Then, why don't you do it now?"

"Let go!"

"Well, well, since you have given me a good idea, it's a shame to not use it, no?"

"Idea?"

"About the replacing stuff. I remembered that I got the Heroic Spirits, Brynhild and Bradamante. Indeed, I can overwrite their feelings, but that alone would be boring, right? Thus, I decided to make them fall for me, reveal my 'identity' and overwrite them."

"You bastard! How can you get more twisted?!"

"No, even if you say that. I feel kind of guilty with making moves on those two since I liked the sh.i.p.s they have in FGO. However, if absorbed the two of you, I will also obtain your feelings for them, right?"

"Don't tell me, what you plan to do is....."

"Oh, so you noticed it, huh. Considering you fused with my Superego, you will naturally know what my Id is. My main Id is nothing like those repulsive whisper you can hear right now. It became like that since I devoured those negativities back then and didn't bother to clean them up. In fact, my main objective in coming here is to solve the problem with those lingering wills. You just happen to be the side line objective."

"After I refine those negativities, my original Id will become more potent than ever. As for what my Main Id is? It's simple."

"To gain absolute control on those that I love."

"My Id have many instinctual d.e.s.i.r.es, but that one stand out the most. After what I did to Miu and Shigure, it surfaced. When I gain perfect control on Gilgamesh, I realized its existence. And when I was very excited and delighted on the thought or controlling Brynhild and Bradamante just now, confirmed it."

"I'm very grateful to you, you know. As a proof of my sincere gratitude, I will take care of your lovers in your stead. Oh? I already absorbed you, huh. No lingering wills and no attempts to gain control of me. With this, I became Ruggiero and Sigurd, rather, their reincarnation. And my Superego came back to me. This concludes my side objective. Next is those lingering wills."

Sai didn't waste any time and went inside the cave.

Meanwhile in Pocket Mansion's Living Room.

Sayaka and Kyouko are sitting on a sofa, while both are holding a card in their hand.

"So, after we absorbed these girls, we can manifest in reality without relying on Sai-kun's Manifestation Spell?" (Sayaka)

"Yes." (Kyouko)

"Manifestation Spell. It allows sentience without form to have a physical body. Sai-kun created this spell for us. Although, it was success, the burden on the user is great. Sai-kun needs to run his processing facilities to maintain our forms, the reason why we seldom appear here. Since, it was only an experimental spell, Sai-kun refused to put it in his Akashic Records: Dawn." (Sayaka)

"The spell itself has it flaws and we cannot use it ourselves since we are only wills of lands. Sai has a lot of matters to resolve and he don't have the leeway to worry about a half-baked spell. That's why when an alternative shown up, he decided to try it out." (Kyouko)

"Do you really think that is the case, Kyouko-chan?" (Sayaka)

"Yes." (Kyouko)

"If so, then let me say what I think. An opportunity to send you away has presented itself. Sai-kun took that opportunity to send you away and solve a certain problem." (Sayaka)

"What are you talking about, Maizono-san?" (Kyouko)

"You already noticed it, right? The two of you are always together, so it's impossible if you didn't notice it. The lingering wills that Sai-kun absorbed is encroaching him." (Sayaka)

With Sayaka's statement, Kyouko showed a depressed look.

"Indeed, and I cannot do anything about it. Sai just ignored me when I'm talking about it." (Kyouko)

"Kazuki-chan knew it already, and the rest of us just managed to realize the problem. Our only clue is you. The fact that you still retain your rationality surprised us. You cut off communications when the lingering wills of the dead are encroaching you, saying that you cannot maintain your sanity. You shut off all of your senses, which is not effective. You said that Sai-kun resolved that issue by extinguishing those lingering wills. I bet Sai-kun didn't actually extinguished them, but absorbed them instead." (Sayaka)

"As expected of Maizono-san, you actually managed to see through Sai. Even though I just realized just now that Sai is resolving that problem as we speak." Kyouko said with a helpless expression.

"I just had a hunch and ask Kazuki-chan for confirmation." (Sayaka)

"I don't know why Sai did that. He can just make them disappear, but absorbed them and risked himself of that danger." (Kyouko)

"The person himself kept quite all this time. I don't think we can get an answer if we asked. We can only speculate but cannot pry. There's no need to worry. The man feared by the world cannot lose to some lingering wills, so cheer up, Kyouko-chan." Sayaka smiled and encourages Kyouko.

"That's right. Sai is the strongest." With this, Kyouko lighten up.

"Let's do what Sai-kun asked us to do while we wait for him." (Sayaka)

Back to Sai's Mind.

"Uwah~. This is terrible." Sai said in monotone.

After the fight with White Sai, he went inside the cave and saw mud-like human-shaped monsters that are groaning while speaking.

"Kill, kill, kill!" "Woman, p.l.e.a.s.u.r.es, P.L.E.A.S.U.R.ES!" "Gold. I want lots of gold!" "Food, give me more food, I'M HUNGRY!" And those words and more came from the mouths of these abominations.

"I better clean them up." (Sai)

Sai concentrated and a cyclone started with him in the middle. The cyclone tears off the human-shaped monsters and drags them to Sai. The monsters became dark violet mists and went inside Sai. Eventually, the monsters and the cave itself were absorbed by Sai.

After that, Sai closed his eyes and remained standing. He is currently let his Id prey on these lingering wills making his instinctual d.e.s.i.r.e stronger, especially his d.e.s.i.r.e to control.

Sai opened his eyes.

"Let's see. No signs of impulsiveness. No signs of going berserk. I'm still rational and my self-control is there. Although the sudden spike of d.e.s.i.r.e happened, my self-control is enough to suppress it." Sai is very satisfied at the results.

"Everything went according to plan, and it even yielded me more profit." (Sai)

Sai hears footsteps.

"As I thought, you came."
