In the middle of the night, in a room where two pink haired children are sleeping on two different beds separated by a night table, one is agirl and she is sleeping peacefully, the boy instead seem like he is having a nightmare as he as a frowning expression and keep moving and turning on the bed.
Ren woke up startled as he seems confused as he keeps looking around the room with his green eyes till his gaze linger on his twin sister, then he let out a sigh.
'My god....to think that I am the reincarnation of a men that lived in another universe and that he more or less knew what will be happening in this world...no wait let me check if everything is like he remember...'
'For what i know, i,my sister,Ino-chan,Shikamaru and Chouji are born in the year 65 of Konoha i didn't met Hinata, Shino and Kiba yet and Uchiha clan land is to far from home....'
'In the same year the 4th Hokage did die to defend the village from the fox demon....but the memories of that man tell me another story...'Thinking till this the young boy was close to having a panic attack just thinking at all the shit going on in his world.
'Oh My God how can one survive in a world where a pedo-snake goes around catching children, women and man to "jump" inside them just to live longer...an old envious racist in the village brainwash everyone to do his bidding all "for the greater good" while he is the only one benefiting...while another older and very stronger ass***e manipulate a member of it's own clan who just want to revive it's childhood sweetheart who in turn manipulate a poor guy with god complex that want to bring peace in this world by causing even more war while the getting manipulated by the oldest mamma-boy ever lived....and do not forget about the alien invasion bull***t'.
Ren then got up from the bed and rushes to the bathroom, once inside he goes to the toilet and start to throw up, once done he goes to the sink, use the step stool to reach it, and wash his face and begin to calm down.
'Ok ... calm down Ren...it's not so bad for you...first both mom and dad are just civilians ninja and only genin at that so no one really important care about them...so if I am careful nothing should happen to my family at lest not until me and Sakura....'
Ren at that point realize 'Shit...shit...mother of all shit...my dear sister is almost at the center of everything first by begin the crush and crushing on the future world saviors and then by becoming the strongest useless person in this world'
Ren was close on having a second breakdown but then force himself to calm down reminding himself 'You still got time, in the memories there are a dozen of way to get strong enough only in this world with things like the bijuu, the sage mode,sharingan ect...but I got something extra...something not of this world...a future Zanpakuto, even if I'm unlucky and got the weakest possible it is still comparable with a strong kekkei genkai and if i get something like Ryujin-jakka and Kyoka-suigetsu well even the shikai form can kick Madara ass and do not forget the special effect of a zanpakuto on souls and spiritual begins so that even in it's sealed form can kill the edo tensei zombie and send back the souls to the pure land and even zetsu is not safe from it..gotta admit in my previous life I choose well'
Once again calm and with a new resolve Ren decide to summon the Asauchi he received from God just as he did the black handle of a katana emerged from his chest.
Ren then chose to pull out the katana and look at it, the handle was the classic black of a nameless asauchi the same was for the guard that was a simple circle the only problem was the blade and the black scabbard that were only 10 cm in length.
'What....wait the size of a zanpakuto is equal to the spiritual strength of a shinigami but I'am in the Naruto world so now works on chakra, that is the union of physical and spiritual strength, something that I have yet to unlock and train in it'
While staring at his 10 cm katana Ren chuckle says"10 cm for a 3 year old boy is not bad...jokes aside at least it will be easy to hide for a while...unless I can put it back in my chest"
So he tried while commanding in his mind to return while pointing the tip of the katana at his chest something the sword did with no problem, just to be sure Ren tried to summon and unsummon the asauchi a few more time before deciding that it is still late night and it is better to go back to sleep.
He goes back to his room check on Sakura, tuck her bedding, then goes to the window and close it, return to his bed and before going to sleep decide to pray 'Thanks God and Truck-kun for giving me this new life I hope that you guys will enjoy my adventure in this world' then start turning around his bed to search for the perfect position to sleep,
not before hoping that he will not have a nightmare about begin chased by a certian pedo-snake 'cause he fancies his 10 cm long sword or that some one-eyed old man kidnap him so that he can have one more slave for the "greater good" of konoha or that a perverted old man with it's crystal ball tries to use on him the talk-no-jutsu about the will of fire non stop for all the night or worse of all that is sister starts fangirling over that emo-boy wannabe brother-killer-avenger, that was something he had to work on...
'or not perhaps is better working on emo-boy that guy I can hit, torment and traumatize as i want but I can't stand hurting my family, in both my lives family was so important to me that Dominic Toretto would be proud to call me bro.'
With that final thought Ren goes in Morpheus embrance.
