With the D-Reaper and the Locomon incident over, the Real World and Digital World were at peace and in close contact, to which people and Digimon could traverse between both worlds whenever they desired.
And while the Digimon Tamers continued with their everyday lives, they would still have to deal with the occasional trouble making Digimon, but other than, that things were relatively the same for them.
Takato continued to work in his family's bakery, he continued to draw, mainly Digimon he would make up, for he wanted to become an animator or illustrator when he grew up, and became quite handsome over the years, to which many of the girls in his high school developed a little crush on him, while Guilmon had matured, both physically and mentally, gaining a more muscular form and no longer acted or thought so child-like, which, like Takato, caused the opposite sex to desire him.
Henry had followed in his father's footsteps and learnt to become a programmer, learning all about technology and how to finely code and construct data, while Suzie had not only grown up as well, she decided to go on a less scientific path and wanted to become a fashion designer.
And while she was only thirteen, Suzie was smart and a quick learner, becoming quite skilled in sewing, to which she managed to make costumes for Takato, Henry and Rika, which were designed after their Digimon partners, patched up Impmon's bandana after it got torn during a fight against a sneaky Shurimon and made Guilmon a nice red scarf, which was of great quality and wore proudly.
Just like the boys, Rika had changed as well.
While she was still somewhat distant when it came to her emotions and feelings, she was more open than she was when starting off as a Digimon Tamer, even revealing to her friends that she wanted to be a singer when she was older, gaining nothing but encouragement, especially from Takato, who told her he had heard her sing and admitted she had a beautiful voice, as well as admitting Rika had become a beautiful young woman, though he kept that information to himself, unsure how Rika would respond.
And with Renamon, while she remained loyal to both Rika and her friends, remaining the same she was, with Guilmon growth, she was another Digimon who fell in love with him and desired for him to claim her as his mate.
However, part of her was doubtful that Guilmon would, due to the way she mistreated him when they were younger, as well as the fact there were Digimon out there, such as Angewomon and Mervamon, Digimon of great beauty and sex appeal, making Renamon jealous and self conscious, making her wish she had a body and boobs like theirs'.
And while the other Tamers and Digimon had new things going on in their lives, with Takato, Rika, Henry and their partners, they were at Hypnos, working with Yamaki and Riley on a new project the pair had been researching, and currently in one of the labs, which held a huge computer screen and several computers, with Riley sitting behind one, while on a stainless steel table was a weird looking helmet.
"Thank you all for coming." Yamaki said, pushing up his sunglasses, before he resumed. "As you all know, with the Real World and Digital World united, many Digimon have come to our world to search for a human to call their Tamer. But with all these Digimon, there are many still causing problems, even teaming up with shady characters, which is why I have asked for your assistance."
"The new Tamers, though capable of handling most of these problems are still in experienced when it comes to mastering Digivolution the way you three have, which is why we want to learn about the bonds between a Digimon and their Tamer through the power of Biomerging." Riley added.
"Now, Takato and Guilmon were originally going to do this, but Rika and Renamon have volunteered." Yamaki said, causing Rika and Renamon to step forward.
"That's correct." Renamon replied with a confirmed nod, making Rika add in explanation. "Being a guinea pig for Hypnos was the only way my mother off my back about modelling."
Curious, Takato asked. "Would modelling really be that bad?"
"She's going to model in America and wants me to drop everything to go with her. She says I should see the world. The only world I want to see is the Digital World, and us kicking butt in it." Rika replied, knowing that while her mother loved and supported her, Rumiko was still being a little pushy with Rika's choices in life.
And it didn't help that Rika's grandmother wasn't there to support Rika, for Seiko had left Shinjuku to visit old friends she hadn't seen since she was in high school.
But understanding her decision, and knowing Rika had made up her mind, Yamaki nodded.
"Alright then Rika. If you can Biomerge, we can begin." He said, making Rika nod and withdraw her D-Power.
"Let's do this! Biomerge activate!" Rika called out, combining her power and being with Renamon's, Biomerging to Sakuyamon, who, after reaching her Mega form, had to ask. "Now what do you want me to do?"
"You see that helmet?" Yamaki asked, referring to the one lying on the table, making Sakuyamon nod.
"In order to study how your minds think while Biomerged, that helmet will read and analyze your brainwaves, which will allow us in uncovering how to achieve this power in the new Tamers." The blond told Sakuyamon.
In understanding, Sakuyamon digitized her Kongou Spear, her armour, leaving her in the black latex ensemble she wore underneath, as well as digitizing her helmet, revealing her face to her friends, showing the front of her silver coloured hair was styled similar to Rika's, while she had a set of beautiful, blue coloured eyes, just like Renamon's.
And had she been paying closer attention, Sakuyamon would've noticed the small blushes on Takato and Guilmon faces from seeing her face.
But more focused on what had to be done, Sakuyamon then laid on the table and connected the helmet to her head.
"Let's get this done." Sakuyamon said, that part being Rika speaking, while Yamaki just nodded in reply, before he took a seat, turning to the computer screen and began typing alongside Riley, monitoring the brainwaves of Rika and Renamon.
"Interesting. They seem to be in perfect sync." He commented, finding the data would prove to be of us in the near future.
However, as the experiment continued, something unexpected happened, to which Sakuyamon started to cry out and writhe around, showing she was in distress.
"What's going on?" Guilmon asked, watching as electric bolts sparked from the computer, as well as the helmet, shocking Sakuyamon.
"Sakuyamon!" Takato called out, looking to see upon the screen, Rika and Renamon's brainwaves were becoming unstable, while their heart rates drastically increased.
"Yamaki, turn it off!" Takato yelled, looking to see Sakuyamon continuing to cry out and thrash around, her body not reacting the way it should be, making Takato want to run over and remove the helmet.
But from the sparks of electricity coming from it, he guessed would put him in danger as well.
"I'm trying." Yamaki said back, continuing to type, trying to find and eliminate the source of the problem.
Guilmon, however, more concerned for Rika and Renamon's well being than his own, rushed over and pulled the helmet off Sakuyamon's head, causing her cries to die down, before Sakuyamon reverted back to Rika and Renamon, both were unconscious and lying beside each other, with Rika on her back and Renamon on her front.
"Rika!" Takato called out, rushing alongside Henry and Terriermon to check on her.
Are you alright?" The brunette asked, shaking Rika gently in the hopes she would open her eyes.
However, Takato stopped when he saw a change in Rika, in the form of a set of fox ears poking out from her head.
"Fox ears?" He questioned, shocked to see them, and further when he noticed that hanging from Rika's lower back, drooping down the table was a orange fox tail.
"And a tail too?" Terriermon pointed out, where the boys then noticed the tail hanging from Rika's behind, which caused Henry to ask. "What happened to her?"
"And what about Renamon?" Guilmon asked, before he went to check on her, to see if Renamon had sustained any forms of damage to her being, but stopped as a pink hue appeared on his cheeks.
"Err Takato... when did Renamon's bottom get so big, and what's with that pink thing on her crotch?" The red dino Digimon asked as he stared at Renamon's body, unsure what had happened to her and why looking at Renamon now was making him feel funny, mainly between his legs.
Looking at Renamon, Takato and Henry gasped, while Terriermon, being a male Digimon, blushed a little, when they all saw Renamon now had a huge, bouncy butt and a vagina.
"You don't think...?" Takato began to ask, but needed confirmation.
"Turn her around." Henry told Guilmon, who did as he was told, leaving both were to shocked to see Renamon now had huge white breasts, around the size of an ee-cup, pink nipples and a belly button on her stomach.
"Renamon didn't have these before." Guilmon commented as he put a finger on her boobs, feeling the softness as he poked and rubbed one a little, which made Renamon moan unconsciously.
As the boys continued to check on Rika and Renamon, Yamaki reconnected the screen, withdrew a set of electrodes, which he handed to Takato and Guilmon.
"Place these on their temples. Perhaps I can get an accurate reading of what had happened." Yamaki instructed, making Takato and Guilmon nod and do as Yamaki had said, planting the electrodes on the sides of Rika and Renamon's heads, which caused a new screen to appear on the monitor.
"This is not good. That malfunction not only merged a fraction of Rika and Renamon's DNA and Data into one chemical compound, but caused damage to their brain tissue." Riley informed everyone.
"So what does that mean?" Takato asked, but got his answer, when he heard Rika let out a small moan as she started to regain consciousness, rose up, but rose in an unusual way, before getting off of the table and stood on fours.
Looking at her with confusion and concern, Takato asked. "Rika, are you ok?"
Rika did not answer.
Instead, the red haired girl looked down at herself, tilting her head in a confused, yet cute fashion, before catching Takato by surprise as she bit into her top and began tugging at it, tearing the material off of her body.
"Rika! What are you doing?!" Takato questioned, blushing as Rika not only ripped off her top, but her bra too, leaving her chest exposed, before sliding off her pants and panties, leaving her completely naked, only increasing Takato's blush.
And while Takato, having grown feeling for Rika over the years, even having the occasional dream of seeing her naked, he never expected Rika to strip away her clothing in such a wild and primal way.
And when Rika saw Takato, she smiled happily, while her tail began to sway around, before Rika showed how happy she was to see Takato as she pounced forward, catching Takato off guard and causing him to fall onto his back, while Rika was on top of him and started to lick his cheek.
"Rika, what are you doing?" Takato questioned, confused by Rika's sudden affection.
However, Rika just ignored the question and continued, which made Takato continue to blush, more so as Rika began nuzzling her head against his chest and let out a content sounding purr as she did so.
From observing Rika's behavior, Henry spoke up.
"It seems that the damage to her mental stability has left Rika without her memories and has reverted her mind to a more primal form of thinking, one where she believes she is a fox and sees you as her Master" He told Takato.
"But what about Renamon?" Guilmon asked, concerned for the vixen Digimon. "Will she too think she's just a simple minded animal?"
"Well hello there, hot stuff." A sultry voice interrupted, making Guilmon turn to see Renamon, looking at him lustfully, while she twirled her tail in her right paw.
"What does a hot girl like me have to do to get a room with a hunk of a Digimon like you?" She asked in an enticing tone, smiling lustfully at Guilmon as she slipped off her gloves and let them drop to the floor.
"R... Renamon? Are you alright?" Guilmon asked in worry, which just made Renamon continue to smirk..
"You bet I am, handsome." Renamon replied as she hopped off the table, walked towards Guilmon, swaying her hips and shaking her breasts enticingly with each step, before reaching Guilmon, where she wrapped her arms around his neck and licked her lips, making Guilmon sweat and gulp nervously.
"I felt you touch my breasts before." Renamon told Guilmon, teasingly rubbing her boobs against his chest.
"Care to play with them a little more?" She offered, liking the combination of Guilmon's shyness and, from his scent, rising urge to mate with her.
"Renamon... h... hold on..." Guilmon stammered out, remaining rational, despite his urges wanting him to push Renamon back onto the table and have his way with her.
"It appears Renamon has also lost her memories and misguided into perceiving you as her Master, Guilmon." Terriermon commented, part of him jealous that he had such a hot Digimon fawning all over him, despite already being in a relationship with Lopmon.
"Master? I like that. So Master, care to turn me on more?" Renamon grinned as she then grabbed Guilmon's hand and guided it down to her right butt cheek, making the red dino blush further.
"For you, I'll do anything you say." Renamon then told Guilmon, leaning into his ear, where she purred. "And I mean anything."
While Takato and Guilmon were both still stunned by Rika and Renamon's behaviours, as well as doing their best to ignore their hormones, Takato managed to remove Rika from off his chest, faced Guilmon and Yamaki and asked. "What can we do? Is there anything that can make Rika not act like this?"
"I'll have Riley and the other top thinkers of Hypnos look into this matter." Yamaki told Takato, before saying to both boys. "In the meantime, take them back to their residence and keep an eye on them."
"Why us?" Guilmon asked.
"In their current mindsets, they trust you the most and could get into trouble if left alone." Henry explained and added. "It also might help if they are placed in an environment they are familiar with."
"Not to mention with Rumiko gone, you two will be all alone and can get to know each other a lot better." Terriermon teased, making Guilmon blush.
And Guilmon blush increased when Renamon suddenly rubbed her tail between his legs.
"Yes, you can look after me, Master." Renamon said, her tone remaining sultry, while Rika barked happily, not exactly sure what the blond haired human was saying, but knew it meant she could be with her Master, making her nuzzle into Takato's neck, enjoying both the closeness and scent of the human she believed owned her.
Knowing that Rika was in no condition to be left alone, Takato gave in, making him face Rika and say to her. "Alright, we'll take you back with us. But no getting into trouble, ok?"
Rika just continued to smile, while her tail remained swaying around, showing her happiness, to which Takato wasn't sure if Rika understood what he was saying to her, but could tell she would follow his command.
"Nice moves, sister." Renamon commented, perceiving Rika as a vixen like her, who too was trying to attract a mate.
"I'll join you." The foxy Digimon then said as she got on all fours and began wagging her tail too, happy to be with her Master.
"I guess we have no choice." Takato sighed, giving in as he looked at Rika.
"Rika, I'll look after you, and do whatever it takes to get you back to normal, I promise." He said, holding Rika close to him in a protective embrace, which Rika didn't understand why her master was holding her that way, but felt comforted by it, making her purr once again.
"And I promise I'll look after you." Renamon told Guilmon, rubbing her body against his legs, making the red dino Digimon worry, wondering which would get him first, Renamon or his urges.
