a great shock wave in the universe cuase it to merge this taisho era japan is part of the hollow earth the distant future the world above the hollow one.

as a female demon slayer went after a demon snuck behind for a swift cut only to fall into a vortext of light thus the women aweken her bed room all cloth in pajamas modern era clothing. this is when she get up and snicked out to went to the cemetery as she dig up a grave with her name on it, "please don't be there, please don't be there, please don't be there." she repeatedly said as the grave dug up she saw a body of a teen women long dead  as it rotten.

"the body is there... so, WHO AM I!" shouted the women out loud, "kanae?" asked a women a bit younger then her with red hair. "riyo.... i .... i'm not your sister am i?" she asked of her sister. that when riyo look at the other body it was rotten corps  as her jaw drop... "you did not know.. did i even have a son?" asked kanae. "y-yes.... what's going on?" asked riyo. 

"first i need to find my son, pita yuki." said the kanae.

meanwhile in a lab isolated from other people a old man lay in his bed as he become very ill to some sort of change current event, five people stand to see their leader the old man dying from an illness, " rose clay genjo honoka, kaito go look for a  boy name pita yuki and with my sabotama it had my DNA, gather his e-pulse.  if the result turn out to true as i assumed then history changed merge giving me this illness, i have, had a son....he have a son." said the old man. 

 whan the five planets heard this they were shock, but was aware of the changes in their surounding, digimon was not the only thing that existed  and their a area called no mans land, finally this doctor yuki, was head researcher of his company on electric phase lifeforms, but dan yuki was not hes last name, and old man wonder of how he gotten a family.

it was after a day of sleep i woke up in a ally way where, i felt different light weighted and thinner, my autism was in a way gone,  stood up getting off some odd garbage where my back was laying, as i streched, "this is some odd dream." i told myself in some odd mumble. but i felt pain in my back, "is this real?" i asked my self thinking my life had skip a few years and at japan with my brother and jasmine, "must be lost." "got lost and my brother is worried."  but one i decided to walk toward a trash with a broken mirror i was a different person.

"no nononono" i said rushing toward the mirror looking at my reflection. i had red hair,  yellow eyes an anime looking face the goggle over head and speed racer uniform. then pinch my face to check if its all a dream i felt a slight pain, i shouted out a long 'no' at the top of my lungs. for i realized that i was my game character from the game digimon time stranger, dan yuki except i change his name to pita yuki.  "this can't get any worse." i asked myself. 

i am  not capable of surviving in the digimon universe, my mentality is autistic i tend to forget things have poor grammer writing and bad at communicating as well as respond to things i am not that aware of my surrounding as people had to tell me to move out the way and such, in fact i cant  live on my own like at all, this is my disorder of ADD, ADHD, and probably i thing i beat myself up for little things, if anything me being in the digimon universe was my own death sentence all i have in my pocket was digivice that came with me it hold no digimon in the storage or in the party. as i panic breath rapidly as it then somehow this feeling started to lock in

"what is this?" i asked myself. in thought my body acts on its own leading to me picking the digivice that came with this game character, i flip it open then press a button as it said the word digimon in a hologram screen, as then it shifted to a gun in my hand i point out to the entrance of the alley way, then pull the trigger. probably not a good idea since out the fire of the digivice turn gun it was a light form from a blob with three stub on its head, to cat head with a tail then a nun in pink headgear to a nun with a blue mouse headgear and a sword. 

"oh god no." i said as i the panic come back, "so nice to meet you, pita yuki." said this nun digimon, thats when another creature came to attack biting my arm. it look like a hyena of purplish grey four and a skull fur symbol surrounded with spots, "uh fuck." i sweared, i fell on my back dropping the gun as the bite on my arm get cold as pixel surrounded my arm. the nun digimon goes for to draw her sword and spoken her words "white clover slash" she cried out  as cut the heyenamon, making it let go of my arm as it take a step back from me.

i stand up i grab the gun and started shooting at the hyena monster let go and and star. out of this feeling comming back i shot the hyena monster with digivice. it scamper and runs off. "what was that feeling i just have right now." i asked "pita are you alright?" asked the mouse nun digimon, "no i'm not! i should not even be here in this world! and i should not be allow to have a digimon!" i snap in panic. "you don't want me, pita?" the mouse nun asked. "sistermon ciel you deserve better then me." i told the sistermon.

"since my mental condition does not allow me to care for a digimon." i told "then what was all that all of sudden." asked sistermon she got me there, "i-i don't know is as if my mental disorder turn to some sort of mental advance order." i told her. i felt it i can oddly think more better then ever least i think, then walk out the ally way into some town in ruin or something, where thats when i notice the hyena monster encounter a oddly purple hair teen with glasses.

he wore a a black shirt with a yellow wave-like print on it and purple sleeves, a grey jacket with dark grey collar and hemlines, blue pants, and dark grey croc clogs. "oh nah nanana nah!" i respond but when the boy said "goodbye!" he cried out loud. "oh no you dont!" said the hyena monster chase after only to notice me thus goes after me instead, it took a few bite of me, as i started to panic once again breathing heavily, as i started to feel cold, and started to drain me. i tried to aim the digivice at it to fired only to drop it, as i fell on my back.

that when some sheer dum luck and impulse i started to my hand started to glow a black aura, a sign of negative emotion some sort, i clench my hand making a fist as i punch the hyena monster in the guts, the digimon that was eating my epulse  gasped for air as it wheeze, getting off me. as sistermon goes for a strike the hyena monster the hyena then to one bite of her that one bite devolved her to a child nun. then once more bite, it my devolved sistermon was being deleted. "no....nonononono." i cried out. "i sorry i so sorry." i told her. "just run from hyenamon." sistermon said. 

thats when something triggered in me i grab the digivice in gun mode and snap sister  sistermon. with the odd iginite black  aura that was from.  sistermon evolve back to her ciel self but the odd negative emotion works differently on her. she was not wild but something else. her eyes were covered by her veil showing the mouse face eyes on the veil in white, as she too a quick draw stand making a references from an anime. "thunder breathing first form thunder clap and flash." thus in lighting speed with electricity she dash behind the hyena monster split in two and reverted to a red blob with three bumps on its head.

"of course we change this." i said to myself. "are you okay pita?" asked sistermon ciel. "yeah purfect nothing said changing event like taking out a hyenamon with a thunder breathing sword technique from a sistermon." i told my digimon partner. "change event?" asked the sistermon. she stare at me. "pita!?" called a women voice i turn to my back and sistermon look behind me, we see a women who not only suppose to be alive, but not suppose to be in this universe. "your real? your okay and real." said the women. "your kana kocho how are you here?" i asked of her.

"please call me mom." said kanna, "mom!?" i was shock to hear that. thats when things change as a kanna grab my hand and runs puling me to chasing the other hyenamon to find a broken green house, as the bloated and large, as the hyena gaze at the green lizard.  i notice some one there as well, a older young man who survived due to defeat of one heynamon. "good you seem that digimon is protecting his partner." said kana. the hyenamon look at the my mother and i as it snarl and start charging. only a glow of power came from the green lizard  erupting in power.

it shrank and thin out to a stand with the boi in glasses and purple hair with yellow highlight. "god damn it. i can't get a break!" snarled the hyena as he quickly turn to boy in glasses and his green lizard digimon. thats when thing go south for the mere moments,  when i pulled out my digivice in its gun form and blasted the hyenamon it reverted back to being a red blob with three bumbs. "pita?!" said kanae "what i panic?!"  i told her. that when my anxiety calm downs as but crises may be averted but, but things had permanently change.

and how it perminately as i felt my advance mental order kick i was not angry but instead  felt some off feeling, a red hair girl arrived, "so you found him dan yuki." said the riyo looking girl. "yes riyo, my son is here." said kanna. "riyo right could you open your arms as if your about to catch someone from falling from the sky." i asked of her. "like if your make a wish for a dream boy or something." i added as a sign  of humer. "alright i humor you but don't think that someone will-" falling to riyo arms was  a white hair boy with black tips at the end.

"great i gain some stupid foresight or something. hopefully this wont be" as a girl fall to my arm, "oh you got to be kidding me chiwa and rudo!" i snaped to rage, "pita how did you know if that their name?" asked sistermon ciel. "how do we know if they're alive." asked riyo. kana the one who claim to be my mother froze in fear at the sight of rudo. 

this when the monkey digimon recovered and a sabotama was toss to me, i slap it to the side as it got a sample of my e-pulse in one, with a that the monkie digimon to grab the sabotama, sistermon goes to arm only to  struck down by the monkie digimon staff, sistermon was glitching out, thus somehow snap onto from the mental advantage order, i lock in to gokuwmon as my body move on its own e-pulse glow as i use it as my own offence,  punching gokuwmon as he block it with a staff. 

sistermon from the phone like digivice  sisteermon was healed from her injuries,  thus more creature appeared not digimon as they attack the monkie digimon making him drop the sabotama as it was crush by the creature paw. then another sabotama was toss to me as i punch it toward the side it was a girl in blue and her sea digimon made of body parts of other sea digimon. giving the advantage this girl grab the sabotama as she left with her digimon and the monkie digimon.  

this led to a new change. as we run for our lives the boy i called rudo awaken, riyo was force to put him down, as he stan on his two feet to run with us. thus a vortex appeared from a fissure made on the ground, and out of  another women came, armed with a sword that look like it can snap in two. she wore a butterfly haori and has similar butterfly hair pin, to kannae. "shinobo?" utter kannae in a whisper. as this sword womanns cosplayer froze in front of kannae. "kannae i thought you were dead." the women called shinobu responded.

 only for the creature to gotten close to strike as shinobu begin to strike it with her sword, it did little effect "what going on are we at the ground?" asked white hair boy. as then the girl i call chiwa started to wake up. "chiwa!" cried out  white hair boy.  as i put her down to see these creatures was aproachi  "stay quiet will ya." said kannae. "rudo." said chiwa i spot on at the guessing of the name. kanna shushed them. "what is going on what are these thing are we at the ground?" asked rudo. of guy with glasses before he could answered. kannae snaped.

 "will you all shut up and so you know were above ground which i would tell you what these thing are if you were talking and but now you got me all chatting now we got the hungry hungry hippo comming for us you see those they're cyberdemons the result man failed attempt to delete digimons. they eat man digimon those in between cyber demons! and in your case you had nto  knotice they're quck to react to sound. which is why i was trying to tell you about but got me snap pippy angry to shout all about it." that is when her one cyber demon pounce at her only for a pink armor fairy digimon to kick multiple time at the cyber demon reverting it back to a digimon"now  that i am all yell out....fairymon." asked kanae.

 as her fairy digimon preped for a fight, kanae draws out a sword. this moment she goes all out with her fairymon. her digimon partner deliver wind punches  and blows to these digimon as we all watched from the distance one by one the cyber digimon was being hell of reverted to digimon baby forms, as shinobu tend to struggle only for her sister to dealt with the cyber demon  pushing her out the as kanae was carried by fiarymmon to the sky as she was toss upward fairimon and kannae perform their final blow. "fiary breathing first form, hurricane screams" from wind blade and delivered kick a turnado was form like a drill.

 kanae and fairymon ended the cyber demon existed in a eruption reverting them to baby level digimon."okay what the fuck is going on?" i asked angrily. "pita .... rudo?" said kanna. "what is going on, why are you with demons? what is this place?" asked shinobu. "lets head back to cleaner hq first i want to see some result on your dna first." said kannae. i gritted my teeth hoping that this is some sick joke of dream. clenching my fist as energy of black epulse glowed. only for it to settle down. "fine. i play along" i said. thus we join kannae and these group of people to a place where something could least be explain
