According to Soh Moriyama, the original plan was for Cool Boy to appear in the Digimon Chronicle manga as Yuji Musya's older brother but this was dropped and as such he only ever appeared in promotional material and not Chronicle itself.森山奏moriyama soh（enDOLPHIN）・玩具イラストレーター (@alnico6221).

==Fiction==
===Digimon Chronicle===
Cool Boy plays the Digital Monster Card Game with Kota Domoto and Yuji Musya.
===Digimon Liberator===
Cool Boy is the head GM of . 
When Shoto Kazama and Arisa Kinosaki want to report about rogue Frozen Knight to the GMs, they travel to the GM headquarters and at the lobby of the GM's building, they look through the list of GMs and see all but one is busy with other players. They click Cool Boy's chat room, with the duo summoned to his room. After greeting his guest, Cool Boy informs them he is not only a GM — he is the head GM that oversees the others.
Shoto and Arisa tell Cool Boy about what had happened to the them. Cool Boy apologizes for the inconvenience, with Shoto insisting it wasn't that big of a deal. He thanks them for their report, though tells them they were already aware of the issue as other players had told them about rogue NPCs already — this fact shocking Shoto. He also tells them about the issues they were having with wild Digimon, with this causing Shoto to realize that if he tells Cool Boy about theirs it would get their new partners ( and ) into trouble and so he refrains from bringing them up. Cool Boy assures the duo the staff of the game were doing their best to make sure the players could play safely and that they would eventually put out an update that would fix all the issues. He then asks them to stay away from wild Digimon, warning them to not get involved with them — informing them that the research done by the debugging team alongside user submitted data indicated all the issues stemmed from the wild Digimon. Shoto agrees to stay away from wild Digimon, with Arisa shocked and whispering about how that was impossible as they already hang out with wild Digimon and have them in their decks. Shoto counters this by claiming Pteormon and Shoemon are fine, as they weren't wild anymore due to now being owned by them and as such saw no reason as to why the rouge NPCs would target them. Possibly overhearing their conversation, Cool Boy cuts them off and tells them players shouldn't befriend wild Digimon — warning them that doing so comes with the risk of them losing thier player status. Shoto asks if that means they'd be banned, though Cool Boy tells them he can't tell them any more as it is confidential information. He gives them one last piece of advice before they leave, to play the game properly so that they can be safe and to follow the advice he had given him.
At an unspecified time around this time period, after Suzune completed her mission to capture , she talked to in the Garden. Suzune asks if Cool Boy was around so that she could report to a GM, with Yuuki pointing to him at the other side of the room as he's mid conversation with Unchained. Yuuki asks if she should get Cool Boy for her, though Suzune decides against it as they were clearly too busy.
The day after his chat with Shoto and Arisa, the game forces every player to log out so the GMs can a 160 hour long maintenance. During this time, Yao Qinglan is hired as a new GM. They also look into Arisa and Shoto's duel history and learn about the new cards they had acquired.
After maintenance, Shoto and Arisa are summoned by the GMs and as such they force their partners to stay inside their D-STROAGE. This just angers Pteromon, since it had only just gotten free from its trading card and now was trapped inside another device. After waiting around, they are called in by Cool Boy who after some small talk points out how often and for how long the two of them log in — much longer than other players — and apologises for causing them to be unable to play for so long. As he asks about what they did whilst logged out, he takes them by surprise when he asks if they were worried about their new friends. He tells them to calm down as he wasn't accusing them of anything and is joined by the arrival of Qinglan. Qinglan enjoys getting to know the duo, having heard about them from Cool Boy, with Cool Boy telling them they know about their new cards and why they know. Arisa cries and apologises for keeping it secret, saying she had been worried that they would've gotten in trouble for having the cards — begging for them to not ban the duo. Rather than ban them though, the two GMs have the duo go through a portal that leads them to an area with lots of Digimon. They're surprised to see so many wild Digimon, though Cool Boy tells them that they're not wild — nor are they NPC — and that they are in fact real Digimon. This fact shocks both of them, with Cool Boy telling the duo that the Garden they're in is where all the real Digimon live as they had no where else to go in LACUNA. With little time to react, Cool Boy asks if they're ready to hear why he brought them there.
Cool Boy asks the duo what they know about Digimon, with Shoto talking about how they're fictional characters used in various media like anime, manga, video games and of course — the TCG. Yao says he's right, though then moves into asking them what "real Digimon" are. They tell them that Digimon are real, with the fictional characters being based on actual real Digimon and that this is done to allow Digimon to be preserved. This information surprises Shoto; he had heard of the "backstory" of Digimon, but just thought it was made up lore for the franchise — not something from actual real life. They explain how I.D.E.A had found LACUNA and modified it for use in Liberator, which lead to them coming across Digimon, and then lead to the creation of the video game. 
Getting to why they brought them here, Cool Boy tells them that wild Digimon do not exist in Liberator. This confuses Shoto, since they obviously do, with him saying that's just a lie they tell everyone. He admits that it is indeed a lie, with the admins telling them that LACUNA's environment isn't conducive for Digimon to survive. He explains that Digimon can only survive for a few days at most in LACUNA, and so the admins send them to the garden and seal them inside trading cards to allow them to live. Further confused, Shoto points out that Pteromon had been stalking them for three months yet was still alive. The admins had checked the data of Pteromon and Shoemon and had learned that they had both lived in LACUNA for over a year, since the beta test, and tell the duo that only a few Digimon (those belonging to the admins and Debug team) had managed to survive for such a long period of time. Finding it odd, they tell the duo they want to investigate and ask them to bring Pteromon and Shoemon to them. They agree, and summon their partners. Everyone becomes startled when Yao suddenly screams, with her declaring that their partners are adorable. She nerds out and goes on a monologue about both of them, as she asks them many questions and chases them around trying to hug them. This freaks them both out, with them asking to be saved from her. As she does so, Cool Boy continues the explanation without her. He tells them that Digimon able to survive without cards are valuable, with Shoto assuming that meant the admins would take them away, though Cool Boy alleviates those worries by saying that wont happen. Instead, they ask them to co-operate with them so that they can study their partners. He tells them they had learned a lot because of Bulucomon, and that they now know wild Digimon had been hacking NPCs and taking in their data as that was one way for them to survive in LACUNA. This however, would cause the NPCs to go rogue. He reminds them that interacting with wild Digimon can result in their accounts being deleted, and invites them to join the game's debug team. As Shoto is confused over regular players being invited, Cool Boy points out that as they can delete their accounts at any time, the duo actually have no choice but to accept the job. Yao tells them that Cool Boy had actually been protecting them for a while, and was making compromises to ensure their safety. 
As they're in the middle of accepting the blackmailed deal, they are interrupted by Owen Dreadnought — who had been eavesdropping on the conversation. He expresses annoyance at the duo being amateurs, feeling they would just drag the admins and debug team down. This upsets Pteromon, with appearing and and laughing at Pteromon. They're shocked to see Owen with an unknown Digimon, and realize he is just like them. Elizamon and Pteromon bicker, though Owen tells his partner to cut it out as there was no point getting involved with amateurs. Yao asks Owen why he had shown up, with him stating he had overheard their terrible decision and wasn't happy with it. She insists that they're just trying to protect the duo, but this enrages Owen with him declaring that it'll just lead to the admins suffering from the consequences of allowing them to join. He claims they'll just run away the second trouble comes, this setting off Shoto. He yells back at Owen, saying he is sick of listening to him, and agrees to join the debug team purely to spite Owen. Owen becomes sick of the conversation, not wanting to talk to a terrible card game player, with this giving Cool Boy an idea. He asks Owen if he would approve if Shoto showed he was a good player and tells Yao to duel him so that everyone can see Shoto's skills. Owen tells them to do whatever they want. The agreement then changes and becomes that Shoto and Arisa can join the debugging team by proving he is a good duellist.
Owen states Shoto has no choice — with Arisa defending her friend and saying that Shoto has a chance to win. Finding Owen to be mean, Arisa angrily yells out how she regrets using Shoto's fandom of Owen to invite him to play the game with her. Owen shows little care to Shoto's like for Owen, and just says he will see what Shoto can do in this duel — with Arisa wanting Shoto to win even more so that it'll put Owen in his place. 
Just as the duel was about to start, everyone is suddenly transported to Lapis Marine. They find themselves in a tower on the beach where they could see girls in bikinis through the windows. This removes Shoto's motivation to duel, as he instead wanted to watch the girls — whilst Arisa and Pteromon become motivated to go see the sights and shop. Cool Boy is surprised to learn the duo had never been, with Arisa saying that she had prevented them from going as the NPCs were strong and she didn't think they were ready to come just yet. They ask why they had suddenly been teleported there, with Yao saying they couldn't duel in the Garden as it would cause the wild Digimon to become involved in the duel and that the tower was a good spot to duel as they were out of sight of the other players. Annoyed at however everyone was chatting instead of duelling, Elizamon tells them to get back to the duel as Owen is very busy and can't waste his time. As Pteromon becomes annoyed at Eliza and Owen, Shoto gains his resolve to duel again and prove Owen wrong. 
In the middle of the duel, Shoto and Arisa are surprised to when Yao uses , a card they had never seen before, with Yao telling them that they had made sure to inform them beforehand how they had identified new wild Digimon. As she tells them how she had befriended and raised , Shoto becomes surprised to learn that even existing Digimon could come with unknown Digimon cards via further digivolutions. Cool Boy then tells them that most of the debugging team had gained previously unknown Digimon cards this way. Arisa expresses desire to meet the debuggers and their unknown Digimon, though Bool Boy points out that Shoto will need to pass this duelling test for them to be able to do so.
Shoto eventually wins, with Yao shocked at him using instead of Zephagamon (unaware he had lost access to Zephagamon). Shoto and Arisa celebrate, with Yao and Cool Boy congratulating him. The GMs receive a message, with Cool Boy realizing what time it was — causing both to quickly leave. Shoto tells Arisa about his childhood history with Owen, with Arisa surprised and annoyed to have only just learned this. Owen tells Shoto he is weak as he lacks the passion to win and just wants to have fun and tells him that if he can't find that passion he never wants to see him again. Shoto didn't hear him say this though, due to some sort of glitch. Though he doesn't remember what was just said, he still gains the desire to one day impress Owen. As Shoto won the match, he and Arisa receive messages saying they been accepted into the debugging team.
A few weeks later, Cool Boy and Yao have Shoto and Arisa attend a debugging team meeting so that they can officially induct them into the group. He has them join him on stage, and introduces everyone to the newest members of the debug team. As they introduce themselves to the crowd, Shoto notices Owen hadn't show up and figures he was avoiding them. Shoto also notices Close, recognizing her from when he saw her running away from Frozen Knight. Cool Boy is surprised when he notices Shoto recognizes someone, though Shoto denies this being a thing. Doubting his denying, Cool Boy simply laughs and says that he'll be even more surprised very soon. Cool Boy tells the crowd that they had been accepted into the team as Shoto had defeated admin Yao Qinglan in a duel, and that Arisa had defeated a member of the debugging team. This confuses Arisa, who says she had never defeated anyone from the team — with Cool Boy, , and insisting she had. Cool Boy's earlier statement then comes to life, as Violet arrives and apologizes for being late. A shocked Shoto and Arisa learn she had been a member of the debug team this whole time. She then personally welcomes the duo as the newest members of the debugging team. 
Two months later, Cool Boy and Unchained have a video call about T.A.L.E's products. Cool Boy informs Unchained that development is mostly going well, though they do have some issues in Digimon Liberator such as synchronization with the D-STORAGE. Unchained figures that must be why Cool Boy is doing field work within the game, and expresses concern about if he's over working himself. Cool Boy plays down their concerns, as he feels he needs to take action so that LACUNA can have peace. After the call ends, Cool Boy leaves for a meeting. 
Altea had told Yao that he wanted Yao to take him to the outside world. Unable to do this but still wanting to do it, she created a virtual version of Shinjuku so that she could at least take him to a virtual recreation of part of the outside world. She doesn't end up taking him herself though, she instead has Cool Boy take him. Altea and Espimon have fun, then after having their fill — discuss business. Cool Boy asks him what he thinks of , with Altea saying he didn't think they were a threat. Cool Boy agrees, since they're weak and lack the primal desire to seek competition. He asks what they should do with them, though Altea says that he should ask Unchained instead. Espimon makes the suggestion to create an isolated environment, where they would live on their own — then suggests the area they're currently in. Cool Boy says that whilst it's possible, it isn't really optimal, and that they would have to spend a long time figuring out a place they could actually stay. Altea says he will continue to analyze the Maquinamon data, and brings up how there's another member of the debug team that has a partner who is composed of biological and mechanical components like Maquinamon. Cool Boy then says how said member had actually been invited to their meeting and should be arriving soon. Shortly after saying that, Chitose Horaiji arrives. He mentions how they had questions about Composite type Digimon, and as Altea brings up how Chitose was the first person to deal with a rampaging Ultimate level Digimon – Cool Boy leaves as he had a meeting to attend.
