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 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,419 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!

some of the endings are crap but it's a fun game. sexy lovable characters and openly freak piss ♥♥♥♥ mindcontrol fetish stuff going on. wish there was more focus on the one-on-one bonding events, there's a billion gifts you can make for each character but only a few dialogue... it's still one of the few strategy games where there's a girl who talks to you about eroge and a guy watches you piss in urinal so it's hard to dislike even when the writing gets inconsistently stupid in some routes. the themes about world destruction are cool and relevant to current reality also
A masterpiece of storytelling. The choices you make have significant impact. Prepare to spend days enduring the unendurable and suffering the insufferable to pave the way for humanity’s future greatness!

The only thing scarier than the sheer scope of this 22-route, 100-ending story-heavy RPG is that, somehow, it manages to justify having such an ambitious narrative. Every emotion, every surprise, and every character possible is in here. By the time you even hit credits for the first time, you realize you’ve only just scratched the surface.
本身不是优秀的游戏,但告别苍月篇让我决定给出好评。我幻想那个知晓了爱为何物的少年终于长大成年,出落得温和而善良,穿着纯白的衣服漫步在弗特卢姆星的夜空之下。
Kind of a weird experience, though maybe just because I am not as big a fan of visual novels in general. The initial playthrough was fine when everything was fresh, but more I played this game to see what branching paths had to offer, the less I felt I was getting out of it. So many of the events are repeated and the ones that aren't it seems like you have to wait forever to progress through to their conclusion. Eventually you can just skip all battles. Also, so many of the stories of alternate branches seem to provide little value. I feel like the "best" "alternative" branches would offer some insight into different events, characters, and the world but these are few and most of them are just kinda ask what if you had to deal with a different weird scenario and a few ways how it could turn out, while offering little to enhance the overall story, if there could be considered to be one past the scenario you are presented with at the beginning. I think I would have liked it better if [spoiler] there was a Last Defense Academy 3, 4, 5, etc where you retained more memories and sequence of events kept changing in response to you looping instead of only doing so at LDA 2 and as part of the S.F route. I don't think the game needed 100 days or 100 endings.[/spoiler]
Про эту игру можно долго говорить, но если описывать её вкратце, то она: классная замечательная прекрасная отличная превосходная чудесная великолепная идеальная крутая топовая вайбовая имбовая кайфовая чёткая бомбическая эпичная потрясающая обалденная офигенная невероятная изумительная шедевральная волшебная клёвая суперская ништяковая отпадная шикарная.
Phew... Well that was a great game! ... Huh? What do you mean that was the prologue?
Voy a escribir en español porque tengo mucho que decir y el inglés no tiene el énfasis suficiente. Me ha encantado. Es un juego que presenta MUY buenas cosas, de buena forma, todo me parece bien, y los QoL que metieron después amenizan mucho más el tener que repetir lo mismo veinte veces. Ahora bien, no estoy satisfecho con como acaba el juego. No el final en sí, si no el como acaba. La forma de organizar los endings en su presentación de cara a acabar el juego. Esto en parte es culpa mía por mi orden en la toma de decisiones, pero a la vez, no debería serlo. No puedo decir más sin entrar en spoilers, pero fuera de eso me ha gustado mucho. Todos los personajes me parece que podrían tener más protagonismo, algunos más que otros, pero todos me gustan de una forma u otra. 9/10 Si tienes 200 horas de tu vida que no sabes donde ponerlas, este es un buen sitio.
Tsubasa best girl.
Honestly, I'm struggling to articulate my feelings about this absolute gem of a game. I played the demo and instantly knew I would like it, but I hadn't the foggiest clue what was in store for me. I was a bit put off by the price tag at first, thinking there was no way this game would ever feel like it was worth the full price, but I was willing to pay it to support a dev team that was struggling despite making several games I loved. Words cannot explain how wrong I was. Most modern devs take ungodly amounts of money and use it as inefficiently as possible, barely upgrading their projects as the price tag balloons. But this game took seemingly little, and did as much as humanly possible with it. These devs clearly loved their work and poured their hearts and soul into this near-masterpiece. I look forward to whatever DLC plans Kodaka has in store, because I would buy it in a heartbeat. Easy 9/10. One of the best new games I've played in a long time
