Digimon Drama CDs and Tai&Sora in it
Lately I have been rereading the translations of the Digimon Drama CDs and they feel like these filler episodes where they are doing some random stuff that are pretty much always ending in them defeating some evil Digimon. It's a nice read and if you know how to speak Japanese I'm sure they're nice audio stories. You can check all the translations on Digital Scratch (not just Digimon Adventure & 02 - just check it out, it's amazing) and on riahchan's journal. Below you can read a summary of those stories that has something to do with Tai or Sora.Digimon Adventure: Character Song + Mini Drama 1 (デジモンアドベンチャー キャラクターソング+ミニドラマ1)

In track 04 Sora is doing announcements over her school's intercom. She introduces herself and starts to read a letter sent by Kari. Kari says she is a fan of Biyomon's voice actor and she pronounces the name "Kachou-san" because her first name is written with the kanji "flower" and "bird". Biyomon explains the name is pronounced as "Atori". The next letter came from Mimi who asked Sora where did she buy her hat. Sora giggles and tells her that she doesn't know. Sora ends her broadcast by announcing the next track - Ashita wa Motto.
In track 06 and 08, Kari is mentioned by Joe who is thinking about casting Kari in a love triangle in his next CD drama together with Mimi and Izzy. He gets the idea about him getting a singing debut because he defeated Digimon attacking Odaiba and everyone was complimenting him.
Digimon Adventure: Character Song & Mini Drama 2 (デジモンアドベンチャー キャラクターソング+ミニドラマ2)

In track 04 they managed to capture Izzy and tie him up. They are still trying to guess who the receiver of that love letter could be. Tai, now dressed as a famous (fictional) private detective Kosuke Kindaichi decides he will solve this case. Since Izzy is writing a love letter Tai concludes it's for one of the girls. Mimi tells the group she knew Izzy likes her and that the others (Tai, Matt, Joe, T.K.) like her too. And if this keeps on going everybody will like her and the whole world will be kneeling before her. Gomamon and Gabumon say if the letter is for Sora he'll be unhappy and everybody agrees with the two of them. Sora is confused by the meaning of this. Joe explains to Tai that if the love letter is for Kari, he would be Izzy's older brother in the future. Tai, not liking this idea, argues that he wouldn't allow their relationship anyway. They decided that the letter is for Mimi but Kari believes they are all wrong.
In track 06 Kari tells everyone that the love letter isn't for Mimi. So Mimi gets mad at her and wants to know what kind of proof she has that the letter is not for her but Kari instead. Kari starts to feel a little feverish and everybody starts staring at Mimi saying she went too far with her criticizing. Mimi still mad talks about how it's always her fault and she is always wrong and how she is not letting Kari get away with everything just because she is a little sick. Biyomon asks Sora if she will not join them in a "fight" and Sora says she is not interested in younger men. Eventually the entire group gets angry at each other and starts arguing. Meanwhile Izzy thanks Tentomon for helping him and tells him for who the love letter is. He tells him but the name is bleeped out but everyone is surprised. In the end Kari asks everyone to listen to her song which is her theme song introduced in the next track.

Digimon Adventure 02 Drama CD: Armor Evolution to the Unknown (デジモンアドベンチャー02 ドラマCD 未知へのアーマー進化)

Meanwhile Davis goes to Izzy's place in order to learn how to use computers so he can impress girls with his new knowledge. Izzy agrees to help Davis out. Davis starts to pressing the buttons and hitting the computer and Izzy throws him out like Matt before. Outside he encounters Ken and T.K. and talks to them in an unusual way. Veemon explains to them Davis is trying to change his image to become popular with the girls. T.K. and Ken are against it since they like the old Davis better. In the department store, the strange man is asking for a heart and since they don't sell hearts he attacks the cashier.
In track number 03 Tai changes his hair a little bit since they are searching for Boltmon who has spiky hair and doesn't want to be mistaken for the spiky-haired guy - Boltmon. The children split into two groups. Tai, Matt, and Yolei are staying there and helping the girls get out of the department store while Davis and the rest will try to find Boltmon. Tai, Matt, and Yolei are talking about how to save the girls and decide to send one inside the store as a spy. Since Hawkmon can evolve together with Gatomon who is inside they all agree on sending Yolei inside.
The first group - T.K., Izzy, Cody, and their Digimon are searching for Boltmon and talk about the Japanese dialect and how T.K. is jealous because he can't do any other dialect while others can. Davis, Ken, and Joe are searching for Boltmon in different area. Ken gets mobbed by his fangirls and Davis is asking himself how Ken can be so popular.
Yolei's plan to go inside the store is to dress as a ramen delivery guy. She gets in and tries to help the girls. When Boltmon tries ramen it's actually pretty bad and attacks Yolei. She attacks him and gets caught too and apologizes to Hawkmon for always getting into trouble. In track number 04 the groups meet again in front of the department store. They explain their plan and how Yolei got caught and is now trapped together with other girls. Matt informs them about their new plan how everyone will go inside and tap dance to get Boltmon attention. Davis goes in first and the store is like the Digital World and changes a person's clothes to reflect what they desire. Since Davis wants to be more like Ken - to have a little bit of darkness - he dark evolves to Digimon Emperor.
Meanwhile Mimi offers Boltmon chocolate to let them out. Since he doesn't want the chocolate Sora offers him a homemade chocolate. Biyomon is against it since the chocolate is for Matt. Sora says that's okay and that Matt will understand since everyone's life depends on it. Then they hear everyone else tap dancing. Tai asks Kari if she is okay and Matt tells Sora he loves her. Sora gets teary and is wondering if why everybody is tap-dancing while the girls are in danger. Biyomon says there has to be a deeper meaning for this.
Davis is still Digimon Emperor and tries to act tough like Ken did as Emperor. He tries to hit Veemon but he doesn't want to hurt him. Everybody "boo"s him because he is not evil enough. When he tries to be more evil Wormmon tells Ken to stop him but they don't know how since they can't evolve. The girls say that if he believes, he can change the Crest of Kindness into a Digimental and he manages to do so. Bucchiemon attacks Davis with Heart Beam and turns him back to normal. He thanks Ken and says regular him is still the best him after all and everybody agrees. The Digimon who was behind all that was Pukomon who had taken advantage of Boltmon's situation in order to destroy the DigiDestined. The DigiDestined decide to armor evolve but before they could do that Joe knocks into them, and they drop and mix up their D-Terminals.
In track 05 the 02 DigiDestined mix their D-Terminals. Yolei uses Digi-Egg of Friendship, T.K. Digi-Egg of Light, Cody Digi-Egg of Love, Kari Digi-Egg of Knowledge and Davis Digi-Egg of Hope. Bucchiemon reasons with Boltmon and the kids subsequently fight Pukumon. The attacks of the Armor Digimon send Pukumon fleeing. Boltmon decides that a heart isn't something you can get, it's something you have to give to yourself. He goes back to the Digital World to start over. The DigiDestined are wondering who made him recognize that. The girls thank Davis and go back to fangirling Ken. Davis says that being like Ken is better because of the girls and Veemon comforts him by saying he will find a good girl if he is lucky enough. The Digimon from the original DigiDestined try to Armor evolve too. They can't really do it but they just make up their Armor digitation.
Digimon Adventure Original Story: 2,5 Year Break (デジモンアドベンチャーオリジナルストーリー 2年半の休暇)

SORA: In this Drama CD you can find Sora's letter to her father. As we know written in October 2000. They went into the digital world in 1999, so this letter is written one year later and 2,5 years before the next adventure. Sora's talking about their last visit to the Digital world and about the research her father's doing. Biyomon couldn't evolve to Garudamon anymore, but in that time the world was in peace, so he didn't need to. She also mentioned that her father is a university professor and that Joe's brother is going to Kyoto to take his classes. She already stopped playing soccer and now she is playing tennis with her mother ~ actually her mother is a coach to her. Sora also talks about all the stuff that happened (her father meeting her mom, her moving to Odaiba, Joe's brother coming to Kyoto). She doesn't believe that all these stuffs were/are a coincidence. In the end, she wishes her father a happy birthday and mentioned that she has never been to Kyoto and she'll go there with her school, but she would love to travel with him and her mother as a family.
Also when Joe is calling his big brother, he mentioned Sora - that she became more feminine.

On the second track it's the summer of 2001. Koushiro was on his way to visit his late parents’ graves, when the Shinkansen he was riding on went into suspended service due to an unidentified system error. He was stuck at Kyoto station. He meets there with Matt and Joe. Since there was a problem with the system Izzy asks Gennai if there is a problem in the Digital World. He responds that something big has happened in Kyoto and it looks like a lot of data has been destroyed. They go to Kyoto's center where they meet up with the rest of the DigiDestined group except for Tai. There they also meet their Digimon partners. They need them to help to restore the energy balance of all four directions in Kyoto. Agumon wants to evolve but can't since Tai isn't there. They decide to put Agumon in the middle and holds hands and Agumon starts to feel their power flowing into him and manages to evolve to Greymon. With his evolution the balance of power is restored. The naval stone who was turned upside down and was protecting the center of Kyoto before didn't go back to normal. The stone starts to talk about how he deserves respect for protecting the city.
