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!

A pesar de que hay cosas mejorables y algunas se vuelven repetitivas, además de algunos finales que son puro relleno. En general el juego es entretenido y la trama es interesante y te deja con ganas de saber que pasará después o que significa tal o cual cosa.
I reached day 100 now I can finally play the game
啊,仿佛和大海一样广阔的支线之水。。。。真相确实做的好但是也狠狠刀到我了。sf真的不ooc吗。我不想打灾厄线啊,剧情锁让我崩溃。遍地,魅领,独裁,青春都不错,鲜血淋漓谁做的啊给我战棋游戏打成追逐了,苍月这人做的不错很有深度嗯对。属于是又爱又恨吧对这游戏。我也不知道我在说啥总之支线真的水到我了哭之哭之。都到这地步了会全打下去的但是真的还是又爱又恨。
The first time when game has so much content i have to plan out my day around it
