Kazutaka Kodaka and Kotaro Uchikoshi join forces for the first time to deliver the ULTIMATE adventure game! 15 students are tasked with defending a school from grotesque monsters for 100 days. Can they make it to the end? And will they survive long enough to uncover the truth?

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!

前期体验非常好,一周目可以说是一口气打完的,推完后都有点怀疑差评都是跟风来的。但往后玩我就懂了,二周目一些线路明显水,且恶心人,特别是有些推到有点感兴趣的线不让你继续,让你回去推别的真有点力竭了,没看攻略推完真相大白篇只能说中规中矩,但听着结尾bgm想起在游戏中经历的往日种种,不管是快乐也好,煎熬也罢,想起推完一周目推完那种想要知道真相的自己总有种释怀的感觉。。。 总体来说是个说好不好说烂不烂的游戏,但我看完一周年的pv还是忍不住回来打了个好评,建议推完一周目看攻略推自己喜欢线,该跳过就跳过,体验应该能好点。
Worth playing for the 1st Scenario and 2nd Scenario alone

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.
Masterpiece of storytelling , especially for meta-fiends
I reached day 100 now I can finally play the game
