The Hundred Line: Last Defense Academy, a captivating visual novel, is a dual-game experience that has been officially recognized as a '1&2 Pack' by publisher Aniplex and developers Too Kyo Games and Media.Vision. This revelation comes as a surprise to many, as the game's structure has been in place since its 2025 release. The game's narrative unfolds over two distinct parts: The Hundred Line: Last Defense Academy, covering the initial 100 days of a student's school life, and The Hundred Line 2, focusing on the subsequent 100 days. This unique approach allows players to experience the entire 200-day journey in one go or explore specific segments. The game's popularity has led to a special physical edition for Switch, featuring a slipcase with new artwork by Rui Komatsuzaki, available exclusively via Aniplex Online Store and Amazon Japan on April 24, marking the game's first anniversary. An upcoming update will enable players to start The Hundred Line 2 without needing to complete the first game, unlocking a 'Chapter Select' feature that allows for non-linear gameplay. With 100 possible endings, players can strive to experience every single one. Aniplex is also set to release the 'Original Soundtrack' with 112 tracks on January 17, followed by a 'Director's Edition' physical album containing 88 tracks, selected by composer Mas afumi Takada, on April 24 in Japan. Too Kyo Games has hinted at an event in 100 days, adding to the anticipation. The game is currently available on Switch and PC via Steam, offering players an immersive and engaging experience.
