Besides the AU of Taichi Yagami & co, there´s also the reality 12 AU of the tamers.
In this case, Ruki Makino´s AU counterpart is a lad named Riku!
Like his 03 female counterpart he´s a cute yet poison-ivy-esque , introvert geek that avoids all sort of sentimentalism. Because of his ethereal , unconventional beauty he´s often mistaken as a girl (which he HATES with passion) and is ready to kill whoever dares to call him “cute”!
Having grown up in a broken family (like his 03 female counterpart he took his folks´divorce pretty bad) he´s not the type of pursuing either friendships nor romantic relationships. He viewed both concepts as eyesores so and every time he received a confession(from both sides) or an invitation to join a cliqué he would always tell them to get lost. He was fated to follow the lone wolf path for the rest of his life until he came across with the word Digimon ( the so called Hypnos company launched a 3-D virtual reality rpg with Digital Monsters ) and became so engrossed with it that in little time he created an avatar and joined the digi-tournaments. He lived, breathed the games, collecting countless of trophies…and eventually he became known as the “King of Digimons” because of his number of victories!
Yet Riku´s goal was to beat Ryo Akiyama, Hypnos´s president and the equivalent of Bobby Fischer in Digital Games. Riku would never believe he was the King until he defeated Akiyama. fav.me/dbaphp6
Akiyama, though, with Alexander Mc Coy (current Yggdrasil´s host) was actually searching among the contestants somebody worthy enough to be recruited as the next batch of Cavaliers (that´s how digidestineds were called in that reality) fav.me/daj3deq in order to protect the gates between digital an real worlds.
So the day he became a chosen, he found himself in the digiworld, at Kabuki Sakuyamon´s temple and two digital twin girls were standing before him and exclaimed at the same time: “ON YGGDRASIL´S NAME, WHO THE HELL ARE YOU?!”
The twins were known as Sistermons and used to be Anubismon´s assistants until he ordered them to leave the digi realm of death and partner with a digidestined and learn about humans that way. The sistermons agreed only because they wished to become the former King´s new companions fav.me/d9ylwkf and declared they would be much better suited to serve Nova Takariyama than the ANgemon that was currently by her side. So when they asked Kabuki Sakuyamon to summon the King , the deity limited to smile and replied:” So you want to serve the King, right…?”
And the priestess did as asked and used her powers to summon the King, her pwoers navigated through the gate only to get a hold of the person who´s currently going by that title and was none other than Riku Makino!
So let´s say that neither Riku nor the Sistermons had a promising beginning. The Sistermons expected a girl and got a fella instead. Riku wished to be given a wonderful, powerful digimon like Omegamon and got a set of female brats which promised to turn his life into a nightmare since he dreaded girls above everything! (He kinda had a girl phobia )
“SERIOUSLY?! GIRLS?!”was Riku´s horrified response “NO THANKS!”
“You wished to become a full fleshed digidestined and the Sistermons wished to serve the King” was Kabuki Sakuyamon´s sweet response “So technically there´s no mistake and it´s not a match that can be dissolved…”
So Riku had no choice but to keep the Sistermons as his new digipartners and get used to live with two nutsy-nutsy sisters. It wasn´t easy but they managed to put aside their differences, become proper partners and ended becoming a nice little family.
Despite Riku not being Nova Takariyama they ended becoming pretty attached to Riku, so attached that -like Angewomon and Ladydevimon for Mirei – they ended competing for his affections and had been like that for years…
