Story

Takumi Sumino is a totally average teenager living in the Tokyo Residential Complex, a place where every day is much like the last and nothing bad ever happens. All that changes when freakish monsters attack the town and start wreaking havoc. A strange creature calling himself Sirei appears and offers Takumi the power to protect those he holds dear... All he has to do is stab himself in the chest! The next thing he knows, Takumi is in Last Defense Academy, a school in the middle of nowhere surrounded by a wall of otherworldly flames. He and 14 other students have been drafted into the Special Defense Unit, a team tasked with keeping the school safe for the next 100 days. How much are they willing to sacrifice to take back their normal lives and save the world from the grotesque school invaders? The curtain rises on 100 days of war and despair...

What is happening now

The Hundred Line: Last Defense Academy is a strategy RPG hybrid that blends tactical combat with visual novel storytelling across PC and Nintendo Switch. Released in April 2025, the game distinguishes itself through an unconventional approach to squad-based warfare - its designers deliberately positioned the mechanics as a counterpoint to Fire Emblem's careful unit preservation, instead embracing a riskier, more expendable approach to character management that prioritizes adrenaline and tactical urgency. Recent activity has centered on the game's growing cultural footprint in Japan. A limited pop-up event featuring new artwork by illustrator REO took place at a Tokyo shopping venue in September 2026, offering merchandise and newly commissioned illustrations that suggest continued publisher investment in the title beyond its initial release window.
