Sofia is a member of the group 3DM8 alongside Ximena and Zoe within the anime Kizuna no Allele. Raised like a princess within a family of opera singers, this background fuels her confident, sometimes selfish, demeanor, though she expresses her emotions sincerely and directly.

Driven by a fascination with artificial intelligence's role in creativity, Sofia boldly proposes implanting AI directly into her head, believing it could unlock artistic perfection or chart-topping success. Her vision for virtual artistry prioritizes technological integration and results over personal connections or individuality.

Actively observing students from groups like PathTLive, Sofia attempts to recruit their lead vocalist, Chris. This triggers Chris's jealousy and suspicion, viewing Sofia as a disruptive threat to her bond with Miracle. Sofia's persistent curiosity about Chris even leads her to attach a tracking device to monitor Chris's movements.

Later, when PathTLive faces sabotage by Ada and is locked out before a crucial performance, Sofia spearheads their cause. She petitions other virtual artists to support rescheduling PathTLive's slot. Initially met with indifference from artists focused on their own priorities, Sofia's efforts help rally support.

Sofia participates in academy activities and competitions with 3DM8. During a card game, her assertive tactics after winning annoy Riz. She also engages in unit battles against other student groups. Her competitive nature surfaces in a festival tag game where she confidently boasts she'll defeat all other participants.

Her interactions with group members Zoe and Ximena show camaraderie. She shares a notable dynamic with Ximena, who harbors a crush on Jessie from another group. Sofia's actions and philosophies occasionally draw comparisons to characters known for pursuing artificial perfection in creative fields.
