Too Kyo Games and Media.Vision released The Hundred Line -Last Defense Academy- on 24 April 2025 for Switch and PC, with Kazutaka Kodaka and Kotaro Uchikoshi writing and Aniplex publishing. Takumi Sumino is pulled out of the Tokyo Residential Complex into a school ringed by fire, where fifteen students form the Special Defense Unit and hold the building for 100 days against School Invaders. Story days alternate with grid based battles, and the choices you make across those days fork the run into 21 routes and just over 100 endings.
Choosing the right build shapes your entire experience. This guide breaks down every option: what they're good at, what they struggle with, and which one matches your playstyle. For optimized builds with full gear sets, see our builds guide.
