In Episode 7 of "Akuyaku Reijou Level 99," winter marks the end of Yumiella's first academic year, during which her isolation intensifies after the martial arts tournament despite regular interactions with Patrick. When Edwin inquires about Alicia's missing belongings and drags Yumiella into the matter, she denies any involvement and reflects on her in-game portrayal as Alicia's tormentor. Yumiella decides to protect Alicia before the bullying escalates, as it could negatively impact her progress, and resolves to keep an eye on her.

Yumiella confronts a girl tampering with Alicia's belongings and learns she acted out of misguided loyalty to Eleonora. Yumiella advises Eleonora not to reprimand the girl to avoid raising suspicion.

As the school year ends, Yumiella considers whether to attend the graduation ceremony. Initially hesitant, she changes her mind to observe the potential development between Alicia and Edwin. Despite her lack of interest in social events, she agrees at Eleonora's urging and unexpectedly gets involved in the preparations, including selecting a dress. At the party, Yumiella intends to encourage Alicia to follow Edwin's path but ends up dancing with Patrick, experiencing an awkward yet revealing interaction that highlights their evolving relationship.
