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!

I really liked the tutorial! 🤘 In all seriousness though, this game has been such a ride. The characters are a bunch of weirdos that I either came to love or hate, with the hated ones just making the former shine more. The story is fun even with some stuff being predictable, some of my theories being confirmed tens of hours later was very satisfying. And the surprises were all the more exciting. The core gameplay is a lot of fun in itself; this is my first tactical game and while I found myself struggling at times, I feel like I really found my stride. The game didn't really hold my hand, so keeping all the factors in mind took some time getting used to. Now that I got it though, pulling wild chains of attacks feels amazing, and so far hasn't gotten old. I'm very excited to see where this takes me. Seems like it's a hyperfixation that probably won't die anytime soon.
[h3]重活一世这一次我一定要夺回属于我的一切卧槽重活一世卧槽重活一世。[/h3]好玩好玩真好玩很上头,而且很耐玩现在快40h了但也就走了几条路线还有一大堆没玩的,但是战斗太拖沓了实在受不了,去打了跳过战斗mod这样子才能勉强玩下去。每天掰着指头数日子为什么不能改为五十日战纪!🤬由于雷苍月的日配所以我用的英配,英配也很不错就是澄野一直在很用力的“hey~!”听多了已被洗脑。最后苍澄太好磕了,而且我一开始完全没get到真的是随着通关剧情路线(点名遍地苍月篇)被两男同性恨吓到了他们对彼此的恶意已经完全震撼了我,事已至此还能说什么祝两位99吧。😋最后的最后小高和刚太有活了,感觉游戏制作人比游戏好玩。🤣
I'm really loving this VN, definitely one of the best that I've read. I'm on my third distinct "route" and each one so far has been really interesting. I like the characters and how even small changes in their behavior often signal bigger plot points. I will say, though, this English localization leaves a lot to be desired, feeling "over translated" quite frequently. Unfortunately my Japanese is not good enough yet to read it in Japanese or else I definitely would.
