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!

小高你没有心
Boinky boinky very good yes
This game gave me hell, and I thank it for that. Having completed all 100 endings I can say that overall, I enjoy the game and the characters. I think there is a lot of interesting plot beats and Route 0 was a stellar opening. Though, Route 0 can get a bit weighed down by the fact that it is JUST the opening, the foundation that opens into 22 more routes. Unfortunately, I cannot give thllda a completely glowing review as there are some flaws. Not all endings are made equal, some felt lazy, others skip half of the hundred days, or you might get stuck going through a monotonous 100 days, day by day. Once you get to grinding for endings the actual gameplay, the fights, get to be such a drag because you're just trying to get that one ending. Though, the parameters for skipping battles has been updated since I played, making the vast majority skippable after you've completed a matching (or similar enough) battle once. There are highlights though, and I think a lot of my complaints can also be the fault of how I played thllda (which was daily for extended marathon sessions over a month while I was between jobs and packing up to move).
Hell nah, Sirei told me to show him my "baloney pony"
總體大多數劇情上是好的!就是某些特定路線太屎尿了~
终于让我给打完全路线了,支持一下小高和打越喵 简单描述一下体验就是一开始新鲜感很足,但是越到后面,就越感觉缺乏游玩的动力,只有想看大家更多的互动以及新的结局的愿望让我继续往后推剧情,但是先品完相对高质的[spoiler]下半区[/spoiler]后,[spoiler]上半区[/spoiler]就更加乏力了,编剧不同,笔力也不同,有的路线上,大家的台词和互动像是样板戏一般,还是非常遗憾... 令人诟病的[spoiler]鲜血淋漓与死亡游戏的确很烂,我一边打一边不断重复着“何意味”,最后只能抛开脑子享受丧尸立绘和尸体CG[/spoiler],但是打完[spoiler]SF的吃饺子结局[/spoiler]后还是释怀了,也算是这么多个小时的努力没有白费吧! 打完后感觉非常疲惫,虽然只是单纯看了很多剧情,但是脑子好累,虽说这个游戏比起亲身游玩更适合云,但是大家也可以购入支持一下[strike]奶龙之妻[/strike]小高和刚
各条线写的不错,但是为了凑够100个结局强行水了很多选项,导致剧情不够紧凑。 适合时间多的人玩。时间少人的不推荐玩。 游戏本质ADV,战斗系统没什么难度,要玩的也不用纠结每场战斗评级。
