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 · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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!

After almost having 400 hours in this game, i promise it's 100% worth your money! This game is really a bang for your buck and you get so much content for what you pay for!!! My only lame complaint is that the game CAN get really repetitive , but luckily they allow the use of at least skipping fight you've already done! Once again, I really do recommend this game, the cast is amazing!!! (except Gaku)
途中までと真相解明編は面白かったからこそ、これはちょっと許せん。 プレイヤーに苦行を強いるだけでなく、キャラクターと社員に対する冒涜だこれは。 どう考えても「小高さん、100個もエンディング作るのは無茶ですよ」という意見が社内で出ただろうに。もしくはそういう意見の出ないイエスマンしかいないのか。どちらにせよ穴埋めのクソみたいなシナリオを作らされた社員はいるはず。イラストもエンディング+の量があるのでこれも苦行だったはず。自分の意見を黙殺された上で上層部のカスみたいなアイデアに付き合わされる下っ端のことを考えられないのは、正直がっかりするし、この会社には先がないと思う。 tokyogamesのゲームはほぼプレイしたけど、もう新作に期待することはないだろう。

Long? Yes Bloated? Yes Messy? Yes Despair? Yes Death and Emotional damage? Yes Would I inject this **** right here in my veins again and again?: Yes Personally, its peak Would suggest it mostly to VN players or heavy readers especially for the longer sections of the game (If you aren't sure the game has a demo available to try)
打的很累后半部分根本没有耐心看,有的结局不错,有时候让我感慨玩的是同一个游戏吗,但很水很烂的线实在太消耗热情了,感谢mod作者能让我快速跳过战斗,简单模式战旗还挺好玩,成就也好拿,但是打完成就之后的一切都是负担了,很多角色塑造完了其他线又有ooc,不推荐买来玩云云得了
rnm退钱写的一坨的粪游浪费我两百块钱和一百多小时,除了卖那个弱智唐人南通啥也不是同人圈也全是低龄化玩第五人格的神人
Charming, with a lovely cast who somehow don't all get stale across dozens to hundreds of hours, and a variety of scenarios across different genres keep the story fresh, even if portions of it inevitably end up being worse than others. Worth seeing through to the end. I give it 100/Lines
only completed 20/100 endings so far and I can already say this is something that for me will go down as one of my favorite games of all time. easily the best project kodaka has worked on and has definitely made me more interested in uchikoshi's work as well. definitely recommend!!
勾十依托,滚,故事线一百条至少89条都是屎
Equally buoyed and hindered by its hundred ending premise, this game may be easier to respect than it is to love wholeheartedly.
因为编剧不一样导致每一条线观感都不一样,有的线太逆天,有的玩的挺不错,但总体还是好评的,不过这个最终结局只能说放飞小高
