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?

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 · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 moves with no price cut behind them went 2 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!

Not worth completing. First route was good and well written. That's like 20-40 hours in. Other stuff is kinda awful. For a game that has 100 different endings, only 10 are worth experiencing.
peak i want eito to vomit in my mouth

Easily one of the best experiences in a game I’ve ever had. I would go as far as saying it’s the reason gaming was invented.
I once got lost hiking up a mountain until I saw a shepherd. I asked him "How far up are we?" and he answered "The Hundred Line -Last Defense Academy." That's how I realized, I already knew the answer. We were at the peak.
Man what a journey this is the first time im writing a review and i dont like to write sooo to summarize it as one who played all endings you dont need to play all 100 endings just play the ones that you enjoy and if you have a friend that knows the most important and enjoyable ones just asks them to guide you. finally i want moooooore im greedy and i want more perfect timelines.
needs more hiruko
已经无mod打完全成就了,大概去掉20个小时挂机去干别的事的时长。如果你是喜欢小高写的视觉小说形式的剧情,没那么执着于推理的话买就完事了。下面是对一些篇章的感想和评测吧(无剧透)。 为他们的故事流泪了四次,在一周目、真相、告别、SF055。说实话一周目和真相线就给我玩爽了,非常值得一打。感觉后劲大缓不过来的也有别的优秀的篇章当后日谈看。先烂再好地来说: 一堆串起来的里线我打的是真难受,尤其是俩匣子鲜血和喜剧,我从来没见过这么烂的东西,偏偏还作为进入SF篇的解锁条件。我想打出055给他们一个好结局,但最后这个好结局也不能说完全好,还有很多问题没有解决,不过看到大家的笑容还是感动的眼泪下来了。里线里我感觉SF和推理的互为剧情锁挺不错的,再就是死亡游戏(面影和饴宫的高光线)。我感觉很烂的:幸运之匣,烂线top1,探索探索还是探索,然后就是一大堆重复对话,又臭又长这辈子不想看第二遍;灾厄之匣,主要是吓人,半夜打的一直在给我突脸,jumpscare,最后拿东西给上半屏幕挡住了过的;鲜血淋漓,杀人魔和丧尸两条线都挺狗屎,觉得你那横版小人快跑追逐战做的老刺激了是不是,倒是不怎么吓人,被气笑了的程度更多一些;喜剧,像春晚,强行搞笑实则尬的没边。可以看主角的一堆啥子CG;坠入爱河,喜欢大铃木、凶鸟、川奈的推荐打,和主线没一点关系了,纯galgame剧情;xx篇,对xx的设定补了一点,但是依旧澄野恋爱脑发力。我觉得结局有点烂,但是可以接受;选择篇明明有可以补充信息的机会但你就是稀里糊涂地结束,看在你篇章短不让我赤石很久的份上先原谅吧,感觉同样是拉上来凑100个结局的;连续防卫由于我打的时候重复战斗已经可以跳过了(不知道是不是因为后来更新了),所以体感没那么糟糕。就是普普通通、非常一般且没什么信息量的结局。 非里线除了幸运之匣我觉得都很值得一打。论人物结局我最喜欢的是独裁,如果加上故事性一起考虑,真相大白、重启、告别、独裁、青春、领魅、休闲、遍地、诺莫科巴、xxxx,我觉得都是很不错的线,至少这些就够值回票价了。告别和遍地是对xx形象的补充;青春篇就是真 动漫里有泪有笑的热血青春剧情(047、048两个结局都很喜欢);领魅这个不多说了,通关率仅次于真相大白,最出圈的含金量。很恶俗但又很邪教;休闲篇的一些比喻和暗示很有意思,我是挺喜欢这种氛围的;诺莫科巴是饴宫怠美的单人线,同时也是高光线;xxxx是唯一一条重点刻画了侵校生阵营各位的个性的篇章,算是另一视角的设定补充。 如果小高真出DLC的话我希望是爱校、爱岛那种,红鲑团也不错嘻嘻,我要玩galgame口牙。我最想看的还是澄野带着真相线的记忆再次重开,拯救所有伙伴,寻找合适的时机解释真相,最后剧情转入独裁线的剧情。小高我是真想看这个。还有你要出DLC的话别让小太刀碰剧本一下好吗,你根本不知道幸运之匣有多赤石,比连续防卫打的还难受。
선택지갈리는 노벨류 웬만큼 해본 사람들한텐 개개개개개비추 시간빌게이츠들만 하세요^^ 개별 루트마다 각 캐릭터들 성격이나 세계관 설정이 중구난방이어서 이건 뭐지 싶은데 거기다가 그 루트 하나씩 해금하는데에 필요한 편의성이 부족함 엔딩 100가지 내세우면 뭐함? 그 엔딩 볼때까지 시간이 쓸데없이 많이 들어감 차라리 그냥 존나 노잼인 전투 없애고 아예 노벨류로 가지 그랬냐 그리고 캐릭터들 인연 스탯 왜넣음? 그거에 따라 달라지는것도 없는데?? 단간시리즈 재밌게 했는데 이건 최악최악이었음 제작자가 겜 장르에 대한 이해가 하나도 안보임
sono sempre stato io il vero the hundred line
打了补丁 把小高写的线全打完了, 小高已经无敌了,被南通cg骗跟风进来打打。我只能说一坨。 领袖魅力已经无敌了,还能吃下去南通的简直就是神人。 事已至此让我们祝福男主和床天长地久,哦不对没床他也能睡。
