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!

感觉玩完100个结局的我干什么都会成功的,真的是被小高和刚调成m了[spoiler] 谁懂游戏时长包含了多少昏迷般睡眠时间,点推荐纯属想陷害愁人 [/spoiler] SF篇乍一看伏笔回收满满(前置都是大粪结局篇啊啊啊啊啊),实则和真相大白篇左右脑互搏令人忍俊不禁,更有喜剧篇诺莫科巴篇等超绝水天数无敌重复动画,最敷衍连续防卫篇更是大份便餐任去一字肌肉记忆连敌方哪天尿哪里都记得一清二楚(绝望)[spoiler] 致敬三观最正最健康最不药物依赖主角最不出卖身体的领袖魅力篇 [/spoiler]
If you like VN games, multiple endings, and multiverse theories, with a mix of strategic combat and funny/ cringe memes, this game has it all. Developed by the guys who made Danganronpa and Zero Escape, which were also really fun to experience. Good times!

哦我的上帝,这简直就像格里芬太太端上来的烤糊的苹果派扣在杰克叔叔的黄金巨蟒上,你永远不知道下一口尝到的是软糯的恋爱sf线还是又臭又长的扫码连续防卫闸子和幽默丧尸线,当你履行光盘行动拿下全成就后,腰也不疼了,眼也不酸了,精神气也上来了,一切的一切都是因为你删掉了百日战机-神人自卫学院
good story
Witty, engaging and addictive. It's pretty much Danganronpa but with Tactic game elements, that I personally enjoy, what are you waiting for join the Last Defence Academy.
牛逼克拉斯呀,除了战斗一坨其余无可挑剔
i love takumi
幹你小高 我被迫目睹同伴不停死亡 但完成真結局是真的爽
老子真要玩吐了,小高你就继续恶心玩家吧,弹丸全系列我都玩了,雾雨迷宫在switch上玩的首发,我以为雾雨迷宫已经够烂了,没想到这还有托更大的史,这煞笔丸子乐和川奈是人呐,纯纯恶心玩家,我这个好评是给你作品建立在反战主义的基础的,但这坨游戏就是纯粹的狗屎
通关一年多了来补个评价 开卖前被小高吹上天,加上在平台的各种抽象宣传第一时间预购了。 实际游玩体验太失望。战斗系统无趣,剧情一半时间在水。不是很想支持百日战纪。 希望小高今年2x2能整点活,就算是v3那种烂活也比百日这种没活的来的好。
