Chapter 1

Out of nowhere, Ace found himself in a completely different world. The cause of the occurrence was unknown to him, much less the process. He simply knew that he had crossed the world.

Besides, he has memories of a completely different person inside his mind; these were the memories of the person whose body he was currently occupying.

As he browsed through the memories, many mysteries unraveled. This was a magical world where people cultivated mana, a form of energy that enables one to use magic.

Here, people advocated training in order to become strong as opposed to studying, like in his previous life.

His current identity was quite noble. He was the only heir of the Shinomiya Household, one of the only three households which hold the hereditary title of Duke.

They are a mighty household with deep influence within the Kingdom, and their roots spread over many walks of life, whether it be military, business, or foreign affairs. They also have a very large territory which generates a massive amount of tax revenue every year.

There was one sad affair however, Ace has no parents. They died right after his birth in an adventure or so is rumored, so his aunt was acting as the head of the household. He was to become the next head of the household, and inherit the title of Duke after he turned 18.

Presently, being only a 10-year-old boy, that wasn't happening anytime soon. Thinking of the body of the boy he has inadvertently occupied, he idly wondered if that boy has ceased to exist. Not that he particularly cared, but a title of pedicide on his head wasn't exactly ideal.

Right then, he heard a buzzing noise in his head and pink holographic floating screens appeared in his vision.

≪Lust System has been successfully bounded with the user!≫

≪Do you wish to open your profile interface?≫

≪Yes≫ ≪No≫

Ace was initially taken aback by such sudden phenomena, but he quickly calmed down and then rejoiced.

A system! As an otaku, how couldn't he understand how valuable this golden finger is? It could be said that it is the best among all cheats one could get. To think he would stumble upon such a great treasure right after crossing!

With some excitement, he dragged his hands and clicked on 'Yes'. Right afterward, another similar screen opened.

After Ace browsed through all this, he couldn't react for a while. Although he expected the system to be somewhat perverted judging by the name, still…

Don't get it wrong. It's not like he has a problem with this however, quite the contrary actually, he loves this system even more now! After all, he himself is quite a little pervert!

But the most regrettable thing is that the current Ace is still unable to get a boner. His wiener remains in the flaccid state no matter the situation. And his puberty won't arrive until after a couple of years.

"System, what is the usage of Lust Points?" Ace asked, a little depressed internally. Hearing him, a cold mechanical voice replied inside his mind.

≪Lust Points are the currency within the system, they can be spend in multiple ways, primarily from purchasing valuables from store. You can also convert Lust Points into pure money, the conversion rate is 1LP → 100 Gold Coins! Additional usage would unlock as user's level increases!≫

"I see, as I thought. Hmm, can you open store for me?"

…

Ace browsed through the catalog and quietly bought [Full Recovery Potion] and stored it in [Inventory] without thinking. Though he felt pity that he could only buy one, he wasn't complaining. An item worth 100,000LP became a freebie, what can he complain about?

After all these things, Ace closed the holographic screen. He then began pondering about his new family and how he should act with them.

The previous Ace has a detached and serious nature, someone who was obsessed with becoming powerful since he came to know that his parents died. You can see his efforts in terms of levels. For a ten-year-old to reach level 5 so early was nothing but short of a miracle.

His detached nature was kind of helpful since he rarely interacted with people other than some core family members like his sisters or aunt. But he didn't dare to be careless.

In this world of magic, possession wasn't unheard of. He didn't want to act abnormally and make them suspicious. That would be troublesome.

...

After a while, Ace decided to visit the library. His objective was simple: understand this world in more in-depth. In the memories of previous Ace, there was information but either they were blurry or incomplete. He couldn't work with it.

Ace exited his bedroom and began moving towards the library. He was awed as he looked around in the castle he was living in. It was luxurious and beautiful, worthy of being Shinomiya's household castle.

He walked past maidservants who stopped and bowed deeply as he passed by. One thing he immediately noticed is how attractive they were. Compared to his previous life, not a single one of them didn't have the qualification to become idols and celebrities.

Idly contemplating if this was due to the presence of mana in the atmosphere, he reached up to the library. He entered inside. Fortunately, he didn't see anyone so he was alone.

Or so he thought.

"Ace? Looking for something particular?" A slightly cold and indifferent voice prompted him to look to his right.

What entered his sight was a beautiful young girl with a head full of straight inky-black hair and deep scarlet eyes, sitting on a chair and reading some book. Contrary to her hair, her fair skin was flawless and full of tenderness which signified her noble birth.

She was dressed in a simple sailor uniform, and her long black hair was tied by a red ribbon. Her almond-shaped eyes were sharp and they exuded maturity that didn't match her age, which was around 13-14.

Ace was momentarily stunned by her beauty. And then he replied: "Not really, just revising the basics."

"I see," Kaguya, his only blood-related sister nodded lightly and focused back on the book she was reading.

There was another beautiful girl standing next to her quietly, who also seem to be around the same age as Kaguya but has a more bustier body as opposed to her slim, feminine one.

Blonde hair was tied on the left side of her head, her eyes were hard to decipher and she was dressed in a full-maid outfit.

'Ai Hayasaka.' Ace thought inwardly. He obviously knew who these people were and he thanked the memories he received, otherwise he would be too shocked to walk straight right now.

What were people from the anime world doing here? He has no idea.

But regardless, he was very excited!

Kaguya in this world was kind of similar to Ace, full of motivation to become strong after she found out about her parent's death. This caused her to grow a cold outlook but in reality, she was a good girl who cared for Ace. Her relationship with him was nothing special, at least that's how it appears to be.

Curious, Ace spoke inwardly, 'System, use [Observe] on her.'

…

Target: Kaguya Shinomiya

Race: Human

Age: 13

Level: 7

Affection: 100

Fetish: Kisses

…

Ace froze in his tracks. His eyes couldn't help but travel toward Kaguya in amazement. Turns out… she is madly in love with him?!

No, he couldn't be sure. For all he knows, 100 Affection might be nothing special.

'System, is 100 Affection high?' He asked the system immediately.

≪Affection distinctions are as follows:

0-30: Friendship

31-60: Like

61-70: Love Until Death

71-80: Love Beyond Death

81-90: Love Across Reincarnations

91-100: Ultimate Love / Obsession≫

"…" Ace was speechless. At this point, he began thinking if he should be happy or afraid?

As that thought surfaced within his mind, he slapped his head. 'Bah! Obviously it's great! What is there to be afraid of? Kaguya is such a cute girl, how could she possibly harm me? Heretical thoughts, purge!'

At this moment, Ace was blissfully unaware that the said cute girl was observing him discreetly and her scarlet eyes were glowing with crazed obsessive lights!

The only one who noticed this was ever observant Ai. And seeing that look, she can only shake her head lightly.

…

Kaguya's 100 Affection left Ace thinking. Should he look for the opportunity and take her down? Although he can't have intercourse, he can still farm points from her. And when he is able, he can make her his own woman completely.

The more he thought of it, the more he felt that he should do it.

'Yeah, such a beautiful girl, why should I leave it for outside pigs? It's better for her to be eaten by me!'

Hence, the matter was finalized.

He then thought about Ai Hayasaka and suddenly wanted his own personal maid. Ai was originally supposed to be Ace's personal maid but this training-obsessed idiot didn't want any personal maid, thus she became Kaguya's personal maid in the end.

"Sigh, what a loss." Ace lamented lightly. Then, his eyes sharpened.

He put all matters out of his mind and began searching for the books he was looking for. While being a pervert, he wasn't a beast who just thought with his lower body. While he owns an incredible cheat in the form of System, his own hard work was most important.

After finding some books he thought he was looking for, he sat down on the ground, leaned against the bookshelf, and started reading.

…

It was a total of five hours later that he finished going through most of the books related to this world's common knowledge.

As he understood, he was in a massive magical fantasy world, which was called Grace Mainland. It was divided into four realms: Human Realm, Demon Realm, Angel Realm, and Monster Realm.

The relationship between the four realms, as one may expect, was very complicated. In the long ten thousand-year histories, there have been numerous bloody wars that went on for years, which has caused a rift between the realms.

Nowadays, the situation is far better than ever, at least on the surface.

Though, it has to be said that Angel Realm and Demon Realm still showed no signs of stopping their war; Monster Realm was still suffering from internal conflicts and Human Realm was still busy securing whatever land they have.
