This film is adapted from the sci-fi novel Nerawareta Gakuen by Taku Mayumura, originally published in 1973 and adapted multiple times into TV and live-action formats. The futuristic themes of time travel and a transformed Earth are impressive considering the novel’s early origin. Visually and audibly, the film is a treat, with stunning animation, detailed backgrounds, and well-matched sound design. However, character development is uneven. While the main characters show distinct personalities, their reactions and emotions often feel exaggerated and unnatural. Seki’s role as the protagonist is underdeveloped and overshadowed by Ryoichi, making his sudden growth confusing. There are plot gaps—particularly the unexplained incident with Yamagiwa, which triggered strict school rules and influenced key events. The characters are supposed to be middle schoolers, yet their appearance and romantic scenes feel more suited for older teens. Despite these flaws, the film offers a lesson on empathy and communication: understanding others begins with open, honest expression. Read the full review here: (Indonesian version : alunauwie.com)
