When Magnus Takariyama by chance arrived to reality 09, a Millennia before the appearance of google boy Tsurugi and his firneds. Clavis Angemon summoned Magnus to the Digiworld despite Magnus was supposed to have landed in the Digiworld from reality 12 and gave him the task of defeating a digimon called Quartzmon which arrived from nowhere and was attempting to take possession of Yggdrasil.
Several digidestineds that were summoned before the lad ended all failing to accomplish the mission and became preys of Quartzmon themselves!
One of the captive digidestineds was Kiyo Zenkō. A girl you could call the personification of discretion, who would rarely speak unless she considered she needed to communicate something important and would rather spend her time on her books than dealing with people…until she was chosen by Clavis Angemon. And she was granted a Pichimon as her digimon.
Thanks to her new comrades she slowly learned to open herself to other people and that it was okay to have friends and not consecrate her entire time into studying. But it was during her captivity under Quartzmon´s claws when she came across something that changed her perception about life. When Magnus Takariyama, his digimons and Akarimon went to their rescue Kiyo was the first to learn about Magnus and Akarimon´s love.
Magnus´s unexpected death and Akarimon´s grief moved Kiyo´s heart like no one did before. Kiyo realized how precious were those moments and how deep, pure was that love. Feeling guilty of not being able to help more, when she was returned home she gave up her status as digidestined for good.
She grew up, went ahead with her life and never spoke about her time as a digidestined. But her heart never forgot. Destiny wanted her back in digital business though, when she passed away in her 70s her spirit was transported to another reality, Reality 03 and was reborn as a Digimon…and she´d eventually become Ruki Makino´s Renamon!
For a long time Pichimon waited for Kiyo. The digimon could never dream that Kiyo would never come back and kept waiting for her tamer. Akarimon eventually would pity the digimon and placed a slumber spell over Pichimon. The digimon would sleep for a milennia until she finally was chosen by Digidestined Ami as her new partner!
But eventually the past will catch up with the present and when Pichimon finally meets Renamon, she´ll certainly recognize Kiyo´s scent underlying Renamon´s codes…
