Before Her time!

[Senju Clan selected...Possibly of Senju clan members existing without violating the character creation rules <0.0001%]< strong>

[Select one of the two starts:]

[Petri Dish]

[Timeline change]

...

He looked carefully at the two options, but none of them really stood out as both of them were bad. The name Petri Dish itself implied that his birth would be the result of an experiment likely similar to Yamato's origin story.

'Would this option give me access to the wood release? Quite possibly yes. Would I enjoy my time being under high scrutiny... Yeah, that would be a no...' he thought. If his life was not on the line he would have entertained the thought of playing with route. As a subordinate of either Danzo or Orochimaru, the amount of chaos he could cause would be interesting to see. 

But not only was his fate on the line but he also wanted to have some fun with Hinata or Ino. However, if he selected the second option he wouldn't be able to guarantee anything.

'A timeline change would go two ways, either the canon itself would change to accommodate my presence, or I would be stuck in either the past or future of the show. I'm not even sure which option would be worse.' He grimaced as he thought about the potential changes that he would have to deal with.

'But I would have my freedom...' He thought and with no other option, he gambled on the Timeline change. Saying goodbye to his canon knowledge he waited as the panel blinked out of existence and was quickly replaced with another.

'No option to go back huh...' He thought as he looked through the result of his choice.

[Timeline Change Selected... Calculation possibility of Senju Bloodlines...]

[Select Lineage]

[Hashirama Senju]

[Tobirama Senju]

[Tsunade Senju]

[Civilian Senju]

...

'Thank god I have options,' he thought as he gave a relieved sigh. The list gave him a lot more options to go through but at the same time, he realized that he didn't have much of a choice to begin with.

'If I select Hashirama or Tobirama, my birth would be at a time when I would know nothing about the world.' He thought but still, the temptation for wood release was a little too much to ignore.

'And it tells me to choose Lineage, not my parents. I could be Hashirama's grandson or great-grandson, that way I would even be closer to canon.' he thought. He looked through the other 3 options as well but his instincts naturally gravitated toward the 1st. He was a little excited as he clicked on [Hashirama Senju]. 

...

[Hashirama Senju's Lineage selected]

[Determining Parentage...]

[Determining Timeline...]

[Choose one Perk]

[Unsurpassable Physique - Your Physique was meant to break the peak of a shinobi's limits. Your body can handle an almost unimaginable amount of stress and grow faster than anyone else. Your body is more resistant to small injuries.]

[Lightning Reflexes - Your Reflexes would naturally increase as long as your vision was able to keep up. The REF stat is locked with the VIS stat and REF can not be lower than your VIS.]

[Keen Insight - Your Vision would naturally increase, keeping up with your agility. The VIS stat is locked together with the AIG stat as it can not be lower than your AGI.]

[Complete Control - You are always in complete control of your body. Your Balance, Coordination, and Flexibility are your advantages. You gain +100% experience in Taijutsu.]

[Perfect Chakra Sense - Due to having lived a whole life without the presence of chakra, you are hyper-aware of the energy flowing through your body. You are more attuned to your own chakra and have a passive sense of chakra flowing all around you.]

...

The next options stunned him, while the system didn't tell him about when or where he would arrive, with no information of either the timeline or his parents. After complaining about this forced concealment of information he read through the next options in front of him. 

This should be the last option available to him as this gave him the choice to select his fighting style in the new world.

'Each of these options is geared toward a stat, so not only am I getting an option to select my fighting style I'm also getting some information about the stats.' He thought. Out of the 5 options, the first one was the one he was least excited about. While an Unsurpassable physique might be good since he selected a Senju as his clan, his Yang chakra would already be quite high which means he would have a stronger body.

'If I combine a strong body with Perfect Chakra sense I won't lose to anyone in two of the 5 stats. And Ninja's relied on Jutsu's more than anything else.' He thought, though he really was tempted with complete control. If he was able to have complete control over his body his fighting power would transcend the meaning of stats as he would be able to use every ounce of his power.

'But a perfect chakra sense is too overpowered to pass up... especially if I get a passive chakra sensing which would vastly increase my survivability.' 

The debate lasted in his mind for a little bit but in the end, he went with his guts, with hesitant fingers he tapped the last option, [Perfect Chakra Sense].

With bated breath, he waited for the next panel, and like he had guessed the character creation period was over.

The countdown finished and reality itself shifted. 

Akuma blinked as the scenery in front of him shifted, while earlier he had been surrounded by complete darkness, and now he found himself sitting in a classroom.

"...is your last semester before the final exams. So pay attention and remember that your final scores would impact your team placements..." An older chunin whose name and face Akuma couldn't place spoke as he talked to the class. Akuma looked around, everyone was seriously listening to the explanation so he also turned around to look in front of him when a particular flash of pink caught his attention.

'No way am I in canon?' Akuma thought but before he could follow that thought, 18 years worth of memories pushed through his brain like a freight train causing him to pass out.
