Sonia Nevermind manifests as a digital recreation within the Neo World Program during the events of the original video animation *Super Danganronpa 2.5: Nagito Komaeda and the Destroyer of the World*. This iteration maintains her identity as the Ultimate Princess but exists solely within Nagito Komaeda's dream sequence. Her physical appearance precisely reflects her time as a Hope's Peak Academy student, complete with the standard school uniform featuring a brown vest and her signature headband.

Her personality exhibits core traits of politeness and a princess-like demeanor. A significant deviation emerges in her interactions with Kazuichi Soda. Unlike her usual reactions, she responds warmly to him, engaging in friendly conversations, agreeing to meet at a café after school, waving at him in class, and later reflecting happily on their time together while looking at a picture of them on her phone. This version explicitly displays romantic feelings toward Kazuichi.

Following Kazuichi's murder, she demonstrates strong determination and bravery. She actively joins Fuyuhiko Kuzuryu and Peko Pekoyama in pursuing the killer, emphasizing her resolve to avenge Kazuichi's death despite acknowledging the danger. During the confrontation with the World Destroyer, she expresses anger at the killer's lack of remorse. Her military training from the Kingdom of Novoselic becomes relevant as she equips an assault vest and employs a rocket launcher with precision against the target.

This iteration meets her demise alongside Fuyuhiko during the failed attempt to capture the World Destroyer. Images documenting their deaths are sent to Nagito Komaeda as a threat. Her illusory existence concludes within the program's narrative.
