As part of the disguise, Leviathan faked its background records. A researcher at L-Corp pretends to be his mother.

Starting the plan, Yujin was transferred to Haru's school during fourth grade. He started playing soccer with the other boys, but due to him wanting to keep the ball all the time, they started to reject him. On that afternoon, Haru approached Yujin and asked him to teach him how to play soccer. The other boys saw how much fun they had and asked Yujin to play with them. At some point, Haru, Yujin, and three other kids were part of a team for a school trip, with Yujin being the guide with the map. Yujin got the directions wrong and their group got lost. Everyone except Haru became mad at him because of this.

Yujin kept studying with Haru and the two started to attend Fujimizaka Middle School. In order to accompany Haru's growth, Yujin kept switching between many android bodies.

On October 1, 2016, Yujin is playing soccer outside of Fujimizaka Middle School to the cheers of his teammates and fans when Haru Shinkai is smacked in the face with a soccer ball. They exchange their signature friendship greeting and then Yujin decides to walk home with Haru, during which they discuss their belief in each others' main character qualities. Yujin parts ways with Haru at this point. They eventually meet again when is posting embarrassing photos for all to see, and Ai Kashiki is one of the victims. Yujin comforts her while Haru runs away and eventually deals with the problem. As Haru exits the AR-Field, Yujin meets him again, and the two continue their talk, Yujin commenting that kind people like Haru are amazing once they begin to move. They split up again, but Yujin continues to watch Haru, his eye glowing ominously red. On October 8, Yujin meets Haru at Kashinoki Books, where they listen to Takeru "Watson" Wato's tale of woe related to his malfunctioning navigation app. Hearing this story causes Ai's father to remember that she has not returned home from her errand. Haru immediately forms a search party, causing Yujin to comment on Haru's unusually proactive approach. Yujin and Watson participate in the search, and eventually Yujin calls Haru to tell him that he found Ai and successfully escorted her home. This frees Haru to go after, the cause of the navigation app problems.

On October 15, Yujin meets Haru after soccer practice and heads to Kashinoki Book with him. When Watson is bragging about his accomplishments in Fantasy Saga, Yujin comments that he only downloaded the game, a sentiment that Haru agrees with. He bears witness to the resulting chaos spread by messing with data and then happily watches when everything returns back to normal. On October 31, Yujin is among the friends Ai takes photos of to send to Haru. He tells them that Haru's going to be late because he's absorbed in a book. On December 23, Yujin is part of the effort in preparing for the Christmas party at Kashinoki Books. He is seen putting a red bow-tie decoration on Haru’s hair and greets him with Merry Christmas. He is later seen with the same ominous red eyes when Haru and friends are nowhere in sight.

On February 11, 2017, Yujin joins Haru and Ai's conversation regarding the L Treasure mobile game. He then asks if Haru is free next weekend to search for the treasure together in which the latter agrees. He then notes that it’s been a while since they’ve gone out together. They then proceed to head to Kameura Seaside Park via train. While on the train Haru comments that he bought bento for the both of them and in return Yujin compliments how delicious his mom’s cooking is. Yujin then remarks how Haru has changed and that he made friends with the famous Eri and Astra. When they get off the train they bump into Astra and Eri and the group decides to treasure hunt together. While on the search for the treasure Haru falls and Yujin bandages Haru’s forehead while Eri questions how the two became such good friends when Haru is the quiet and well behaved type while Yujin is the outgoing and dependable type. The group is later split up when they head towards Kameura Natural Park. Yujin is stuck with Eri on a speeding train while Haru and Astra faces off with an infected to stop the train from crashing. At the end of the ordeal Yujin explains to Eri that Haru’s earlier text message helped ease his fears while on the speeding train. He goes on to explain that in reality he’s the one that has always depended on Haru. This starts a series of flashbacks in which Yujin explains how he transferred to Haru’s school during the 4th grade. In the flashbacks, Haru approaches Yujin and asks Yujin to teach him the ways of kicking the ball. Yujin notices that Haru had a great time despite not knowing how to play which helps Yujin realize that he was too focused on winning to the point that he did not truly enjoy playing anymore. Younger Yujin and Haru later agree to be friends, and in the present time Yujin states that he is glad to have Haru by his side. After the Applidrivers return from the Deep Web, Yujin greets Haru at Kashinoki Books.

During spring, Yujin and Haru decide to hang out with the former surprising Haru upon their arrival.

Haru apologizes for leaving Yujin on such short notice and Yujin responds that Haru seems different from before and reassures Haru that he is on his team and will listen to anything he has to say. Yujin is then guided to a sushi restaurant as all traffic lights turn red on his path, and receives a phone message about winning a ticket that allows him 10 sushi servings on the same restaurant. Entering it, he receives a plate with 's Appmon Chip on the sushi conveyor belt and then another one with an Appli Drive DUO. The Appli Drive DUO asks him if he has a friend he would give up his life to protect, and he answers "Yes". He then goes to the AR-Field where the other Applidrivers are fighting Tubumon and, stating that he is there to protect Haru. Yujin Appliarises Offmon and asks him to use his power and the two proceed to fend off Sateramon and eventually defeat. Yujin reaffirms that he is there to protect Haru after the fight. At the Secret Base, Yujin attempts to comfort Offmon and tells him that the others aren't as scary as he thinks. The group starts conversing and eventually Yujin explains how he received his Appli Drive DUO. At a later time, Offmon runs away from the Secret Base due to a misunderstanding while the group searches for him. While searching for Offmon, Haru apologizes to Yujin for not telling him about Appmon, to which Yujin replies that he understands. The group later runs into an infected which causes Yujin to Appliarise everyone for a power boost. After they defeat Musclemon, Haru walks home with Yujin and they resume their conversation.

Their conversation is observed by Rei Katsura and. When Yujin arrives home, his memory is scanned at the doorstep and his "mother" tells him she has prepared pasta for dinner.
