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 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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!

千万别玩
百日玩了240小时 目前除了sf线其他的结局全部打完了 我的评价是这款游戏要是评分只有7~8分 可玩性还是有的其实比较推荐 因为我很喜欢那种大逃杀的风格剧情烂一点也没关系 但是除了sf线的其他结局 部分结局太水了 甚至选择在前面的我都知道后面选择结局如何 一周目剧情还行吧毕竟有很多谜团 我目前也就推荐真相大白可以玩玩了但是玩一半就已经知道结局如何了 没有任何反转。。 但是接下来我要评价一些我真不太喜欢的结局篇章(包含剧透) 连续特防:打的想吐 一直在重复像是水剧情 坠入爱河:这个不做评价我打1分 选择:(选择这个跟凑结局没啥区别) 伊娃篇: 我很好奇主角大决战都没有来那个所谓的炸弹为什么还不引爆?我以为后面还有反转 虽然我很喜欢伊娃 但是伊娃怀孕我是真没看明白。。。 鲜血淋漓和灾厄之匣还有推理:大逃杀剧情我很喜欢 但是我很好奇一点血流干了就救不了人了 那为什么还会有身子砍了一半就把主角救活了。。? 推理篇我不是太理解比留子会同意把主角关进去 100天锁会自动打开??就为了看尸体吗? 诺莫科巴和杀死苍月之后的大部分剧情:很多角色严重ooc 我是真没有看明白 ooc一点点我觉得倒是无所谓 这个看的我是真的很来气尤其是死亡游戏篇 整体下来不推荐原价买 想玩的建议等打折

Really fun and enjoyable characters and story, still on the first playthrough around day 50. Cant wait to see where things go and running it back. Update, finished the first 100 days and started the "real" playthrough and sheesh this game is good man. If you get the romance route first, either skip it if youre not into it or power through because slasher arc is too good.

no game was ever more perfectly made for mentally unsound perverts
It's like Fire Emblem. Not because it's a SRPG, but because you can bang your sister.
The game is not that bad and if you are into VN may be a really good purchase As a interactive game its not great after a certain point, it really repeat itself because the mechanics aren't that deep I'm right now ~100 hours in and I would say almost completed it, my biggest complain are: it drags on very long and some subplots are totally unnecessary or boring (at least for me but I would say for any adult) Honestly if you are not a VN fan (I wouldnt consider myself so, I played some game with heavy narrative though but usually far shorter) you'll better start with something different, unless you want to invest a significant amount of time (I consider people to actual read/play without skipping too much or using guides)
best game ever
After playing through all endings the game has to offer, I can confidently recommend giving this a shot. If you like Danganronpa or Zero Escape, you'll most likely enjoy this game. The gameplay mostly consists of visual novel segments, in addition, there are SRPG battles, which I didn't find very hard on the normal recommended difficulty and then there are exploration missions that are done in a sort of board game fashion. The visuals stay interesting with the many sprites each character has and occasional CGs (there's a TON of them). The battles you go through every now and then are fairly easy but definitely satisfying. The game has 100 endings, which is a lot but as expected, the quality of routes varies. Most of the routes and endings are good in my opinion, with only a few being a slog to get through. I wouldn't recommend rushing through any route, even if it feels annoying or boring as that could just ruin your experience with the game as a whole. I love the cast of characters. Of course, some of them have a few annoying quirks but that's very normal for Danganronpa-style character writing. If you know that you really despise those kinds of characters, then this game probably isn't for you. I personally had a blast playing this and recommend at least checking out the demo if you're on the fence about getting this game. The demo should give you a pretty good idea of what the characters are like and the direction the story is taking. There's quite a bit of content to play through in the demo and if you decide to buy the game, your demo progress will carry over, give the demo a shot! My overall rating for the game would be 9.5/10, I thought this was a really great experience!
i have mixed feelings. please buy it, though. please behold it.
