"As Sasuke pondered over which option to choose, he realized something was amiss. After much contemplation, it dawned on him that the system lacked certain features. His recollection of his past life might have been hazy, but he remembered that in novels, systems typically offered more, such as status points awarded for defeating enemies. It seemed the explanation of the system was too brief and incomplete.

Reading Sasuke's thought, the system was interrupted.

'You're overthinking it; the system wasn't meant to be activated before adulthood. Now, you have to complete a mission to completely activate the system. If you wish to understand more about the system, you should inquire further. Alternatively, you could simply say 'status' to get an update.'"

"what is difference between being fully active and being half active?

Currently, there is a system mall where you can buy skills and items using system points. Additionally, there is a system space that includes a small house and area but lacks any special effects.

Once the system is fully operational, you'll be able to order anything you desire, provided it's reasonable, with system points.

As you transition between worlds, your strength will be scaled accordingly. You'll earn ten times the system points for each achievement or mission completed. You'll have control over the life and death of every harem member and the ability to manipulate time within the system space. Additionally…

I suppose starting to travel to another world when I turn 18 is a viable plan.

Feeling the system's silence, Sasuke wonder if something is being withheld from him."

"When I reversed time, my intention was to preserve your strength, but it inadvertently preserved your age as well. So, when time is reversed, not only your eyes and memories are preserved, but your age remains unchanged.

I understand that you're currently 12 years old, not 14. Given your age, I can manipulate your body's time to age you. However, there are limits: your age could go a little lower than 11 years and a maximum of 17. Unfortunately, this means that the system won't activate during this time.

Stolen from its rightful author, this tale is not meant to be on Amazon; report any sightings.

''As for your kaleidoscope ability, which can also control time, it's important to note that no ability can alter your physical growth. Your age is already fixed, and abilities cannot change that."

"Before Sasuke could comprehend the meaning of the system, it spoke again, assuring there was no cause for concern. To fully activate the system, one only needs to collect a sufficient number of goddesses, thus bypassing the requirement to turn 18.

As Sasuke spoke, the system asked, 'How many goddesses do I need to collect?'

'Twelve,' system replied.

'do you believe any goddess will just simply agree to join harem'.

'With your capabilities, they would kill you before you could engage in any misdeeds.'

'So, what is my course of action?'

"Although I may not be fully activated, I still offer numerous functions to assist you. It's important to work diligently to enhance your strength. I can provide you with skills and equipment, and I can transport you to various worlds to acquire knowledge that will empower you. The skills I offer must be learned, and you must apply the knowledge gained. I will select the world, but you will decide how to engage with it. You can accept or decline the missions I present to you, so there's no need to overthink them."

"I didn't anticipate a lecture."

"Just stop overthinking."

"So, where should I begin?"

"We could start in a world where the risk of dying is low but rich in knowledge, allowing you to conserve system points to exit when necessary. Alternatively, you could opt for a world where gaining strength is straightforward.

"Indeed, there are options like Harry Potter and DC. Given your unique chakra and magic properties, the Harry Potter universe is ideal for you to learn and integrate new skills into your combat style. Alternatively, the DC universe is teeming with formidable individuals from whom you can learn and grow stronger. And let's not forget the goddesses of that world; if you manage to get Wonder Woman, a reward of 20 million system points awaits, along with full system activation."

"It's a tempting offer, but he's not naive. Even a being as powerful as the Sage of Six Paths would perish unknowingly in this world. The Harry Potter universe is more suited for him compared to third-generation Dumbledore's gentleman. He just hopes those fan fictions are not correct.

'Let's begin,' Sasuke said.

'Wait; you need to reduce your age, and if Kin is accompanying you…'

'Do I have to use my own kaleidoscope to change myself and Kin?'

'I could assist, but you currently lack the system points.

In order not to get confused after arriving at Harry Potter World Sasuke decided to ask if system can explain how system going integrate him into the Harry the Harry Potter world.'

I'll arrange some funds, a house, currency, and identities for you both. At least this way, you won't have to handle any unusual parents.'

'You can enter the system space. I'll diverge the timelines so that when it's time, you can return at the exact moment.'

With hopes of no further complications, Thinking this Sasuke steps into the system space.''
