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!

The best game I have ever played (so far). The very epitome of shattering every expectation at every opportunity in the best possible way. Do yourself a favour and play this masterpiece.
Only done one route and started my second route. This game is pretty damn good

Genuinely such a fun and engaging game. Highly suggest playing if you love story driven games with bomb ass combat and idk what games to compare this combat to but i found it so engaging and suited the game SO WELL. It has become one of my favorite games of all time!
It's a very good game! Mechanics-wise, the combat is a good mix of interesting puzzle-y things and fun to break, but the exploration minigame does get annoying when the upgrades get really expensive. Writing-wise (y'know, the meat of the VN) I don't really have much to say beyond it being very good! Some characters took a bit to grow on me but by the end of the prologue I liked (or liked to hate) all of them & after that watching them interact was always fun. After the prologue it did feel to me like a lot of the rougher edges of each character got sanded down, but I've only played three routes total since I managed to stumble into the true ending by accident, though I imagine that kind of development is a little more spread out when they can have a route dedicated to each character. Overall I'd definitely recommend the game; if you think it's gonna be your kinda thing it definitely will be & even if you're on the fence, I'm not normally the kind of person to play these games, but it had me hooked from the first hour & still has me interested enough to go back and read through the other routes after I've seen the true ending & played for 60 hrs.

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.
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!
danganronpa meets persona meets triangle strategy in the best way possible edit: the games 100 endings allow the devs to basically create fanfictions with these characters and put them in the game as endings
玩法还不错啊,剧情也是写的让人印象深刻,我觉得值60块钱吧,一两百买就不太行了
