Kazutaka Kodaka and Kotaro Uchikoshi join forces for the first time to deliver the ULTIMATE adventure game! 15 students are tasked with defending a school from grotesque monsters for 100 days. Can they make it to the end? And will they survive long enough to uncover the truth?

Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.

Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 2.71/day in the week to Aug 2 → 2.43/day in the week after.
For scale, across Steam · Top Sellers · Poland over the last 30 days: the 21 chart moves that followed a price cut of more than 20% went a median of 12 places towards #1, and the 2,501 moves with no price cut behind them went 1 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
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...
Takumi's choices will decide his future, but there's no telling what kind of consequences these decisions might have...
When the invaders attack, it's up to you to protect the school in SRPG battles.
Use each student's unique Specialist Skills to turn the tide of battle in your favor!
Spend time with your teammates to deepen your bonds, or explore the wilderness and ruins outside the school.
You can even use the items you find to craft gifts and get even closer to your allies!

Reviews
This game is worth the cost by a large margin. I loved the game, and would play it for 500 more hours if the content was there.
I now understand why they want to branch away from the Danganronpa series
你是谁?请支持百日战纪! 一编:一口气打到50天花了11小时,果然是量大管饱!剧情中搞笑的部分嘈的不行,笑了好几次;而且还有呼吁环境保护的意思,不单单只是个游戏而已;目前遇到的四回合的战斗算上中间的剧情部分要差不多40多分钟才能打完,目前中等难度没有遇到过战斗失败的情况,机制很容易了解,虽然一开始看到回合制画面的时候感觉有点抽象,但是真的打起来感觉燃的不行了姐哥几个,偶尔还觉得很悲壮,角色死的时候也不是白死,会提升voltage,对战斗来说挺友好的。而且开头在“幽灵”和那些部长变成人形的时候,就感觉很有隐情啊,可能会大颠倒,对剧情超级期待。 小高你继续出吧别管我们的钱包!!

The Hundred Line was the friends we made along the way
I have finally 100% The Hundred Line Last Defense Academy and in all fairness i had like no idea where this game was heading like 76% of the time cuz it knows how to lose the plot regain it lose it then regain it over and over but was it worth 134 hours? HELL YES!
Gaku is based
A must-have if you liked Kodakas previous games. Or if you haven't played them, this game is worth every penny.
플탐 130시간 중에 80시간 정도는 그냥저냥 할 만한데 반복 플레이에서 오는 지루함+편의성 부족 때문에 50시간 정도는 지옥 같음.. 그나마 평 괜찮은 루트만 골라먹으면 못 먹을 정도는 아닌데 올클은 도저히 추천 못 하겠다.... 그거랑 별개로 공식 한글화는 감사합니다
A história desse jogo parece que foi feita por um crackudo e eu adoro ela por isso
