Rascal Does Not Dream of a Sister Venturing Out

Kaede's bruises are a physical manifestation of her Puberty Syndrome, which resurfaces when traumatic memories are triggered. During the exam day, a former classmate's intrusion brought back painful memories of her bullying, causing the bruises to appear again. This indicates that her psychological trauma is still linked to her school environment and social interactions.

Earlier in the film, Sakuta notices bruises on Kaede after she submits her application to Minegahara, foreshadowing that the pressure of returning to a traditional school would trigger her condition.

Kaede was questioning whether Sakuta was supporting her genuine desire to recover at her own pace or simply pushing her toward the version of her that society expects. She felt he might be encouraging her to return to traditional school (Minegahara) because it seemed like the 'normal' path, rather than truly listening to what she personally wanted. This reflects her fear of being forced back into an environment that hurt her.

The counselor meeting early in the film already showed Kaede overwhelmed by expectations, setting up this later confrontation about whose dreams they're actually pursuing.

After meeting Uzuki Hirokawa, an idol who also attends online school, Kaede realized that traditional school and online schooling aren't mutually exclusive. Uzuki showed her that she could have a public career while pursuing education in a way that suits her needs. Kaede decided that online school was the better fit for her current psychological state, prioritizing her well-being over the prestige of attending Minegahara.

Sakuta attended an orientation class for the online program earlier, discovering it as a viable option before Kaede made her final decision.

Uzuki shared her own experience of initially skipping traditional schooling due to her idol career, then transitioning to online classes. This showed Kaede that online education isn't a lesser alternative but a legitimate path that can accommodate different lifestyles and needs. Uzuki's testimony helped Kaede see that 'normal' looks different for everyone, giving her the courage to choose what truly works for her.

Sakuta first saw Uzuki's testimonial during the orientation class, planting the seed for this eventual meeting.

Kaede fell ill during lunch on exam day, and when a former classmate intruded on her in the nurse's office, it triggered vivid memories of her past bullying. This psychological flashback caused her Puberty Syndrome symptoms (the bruises) to resurface. The confrontation with this painful memory was too overwhelming for her to continue with the exam, leading to the emotional confrontation with Sakuta.

The bruises Sakuta noticed earlier after submitting the application hinted that the pressure of returning to school would reactivate her trauma.

Sakuta had been strongly supporting Kaede's goal to attend Minegahara, her original high school, without fully considering whether this was truly what she wanted or what was healthiest for her recovery. When Kaede confronted him about supporting 'the other Kaede,' Sakuta realized he might have been projecting his own hopes onto her rather than genuinely listening to her needs. This moment made him reflect on the nature of supportive family care.

The counselor had already suggested online school might be better suited for Kaede, but Sakuta initially continued pushing toward the traditional path.

After the exam day incident, Sakuta read Kaede's journal which contained her inner thoughts and feelings about her journey returning to the real world. The journal revealed her fears, hopes, and the internal struggle between wanting to meet expectations and needing to protect herself. It helped Sakuta understand her perspective better and recognize what she truly needed versus what he thought she should want.

This moment connects to earlier scenes showing Kaede retreating to her room and keeping her struggles secret from Sakuta.

After the school counselor suggested that online-based high school might be a better fit due to her absences, Kaede felt overwhelmed and uncertain about her future. The meeting made her confront the reality that her past trauma has practical consequences, and she wasn't sure if she was ready to face a traditional school environment. She retreated to her room as a coping mechanism when faced with this difficult decision.

This retreat mirrors Kaede's earlier behavior when overwhelmed by Puberty Syndrome symptoms.

Puberty Syndrome is depicted as a psychological condition that manifests physically through bruises and other symptoms when the affected person experiences trauma or overwhelming stress. In Kaede's case, her syndrome is triggered by memories of bullying and the anxiety of reintegrating into school life. The bruises appear when she's reminded of painful experiences, serving as a visible representation of her psychological wounds.

Kaede's condition was established earlier in the series, with the bruises being a recurring symptom tied to her traumatic memories.

Although Kaede was accepted to Minegahara because the school needed to meet a class quota, she had already decided to pursue online schooling by that point. After careful consideration and her conversation with Uzuki, she concluded that online school better suited her current needs. She weighed the pros and cons but ultimately chose the path that felt safer and more supportive of her recovery, prioritizing her mental health over returning to the school where she experienced bullying.

The counselor had mentioned that online school might be a better fit early in the film, and Uzuki's story later confirmed this option could work.

The film takes place as Mai Sakurajima is graduating from high school, which creates a sense of impending separation for Sakuta. While Mai's graduation is acknowledged in the background, the primary focus shifts to Kaede's storyline. Sakuta is also preparing for university entrance exams while supporting his sister's journey, creating multiple pressures in his life. Mai contributes by tutoring Kaede, showing her continued involvement in the family.

The film opens with Mai's graduation celebration, establishing the theme of transitions and changes.
