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 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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!

感谢200小时的陪伴,小高啥时候出dlc我现在没法释怀
Hundred Line is a wonderful time. I enjoyed the characters, I enjoyed the story, I enjoyed the battle mechanics. I ESPECIALLY enjoyed the OST. Getting to play Hundred Line is awesome. I was so addicted. however.... HUNDRED LINE 2 IS A SLOP FEST, AND HALF THE ENDINGS ARE SO GOD AWFUL THAT I'VE GENIUNELY SPENT OVER A YEAR NOW PLAYING IT IN SMALL CHUNKS Sorry to spoil anyone, I'll keep it as vague as possible, but to those unaware, Hundred Line 2 is the title for the game after completing the first plotline. This is basically the part where all your flowchart decisions come into play, and oh my god. Is it something. I'm marking this review as positive, solely for the fact that the first plotline, and SOME of the flowchart segment is great, and definitely worth the price, but this is quite possibly the most middle road game I've ever played. I both love it so much, and can't bare it simultaniously. It gives me the feeling that the idea behind this games development was more headstrong on getting the ball rolling, that they didn't have the manpower to actually... STOP the ball rolling. I was fortunate enough to start off with arguably one of the best endings once I got to the flowchart part of the game, and even then, I saw the cracks. This game promises 100 endings, which is very much true, but 80% of those endings is you dying or messing up. I haven't even seen a good half of the flowchart, but I can just tell such is the case. I came to realize how underprepared they were when the aforementioned bad endings basically just showed a screenshot of the enemies or the subject matter in blender. Grey backdrop and all. I am not actively trying to ♥♥♥♥ on the development of this game, because I think the fact that Too Kyo Games managed to pull this off as Kodaka's last ditch effort, where he said he was contemplating quitting game development all together if this game flopped, is a miracle of its own. But what I AM saying is this: If you play this game with the intent of getting everything done, and seeing all there is to see, prepare for insane burnout. It is by no means terrible, but it can get really tiring, really fast. Despite everything, I still love this game. I heavily suggest giving this game a go if you're interested. If you're new to visual novels, go play something else first to see if it's your thing. This is a horrible first game to get into the genre.

fun game good story it's got the #sauce
After 148 hours….i did it! Good game…
Найс сюжет: - 100 дней пролога - перемотка времени назад - 90 концовок фанфиков и 10 вменяемых Я сюжет и лор хочу узнать, а не смотреть как Даруми с Рыбой вместо башки ходит и Коко решает устроить резню без причины
省流:如果这部作品只留真相大白篇一个结局同时把价格和流程压缩到跟弹丸一样再把其他做的好的线改成DLC我会把它奉为神作 优点:真相大白篇的剧情写得很好,是彻底的反战而不是反战败,一个日本人能写出这样的作品很难得。小高写的其他线体验不错,人物塑造鲜明,苍澄姐吃爽了 缺点:剧情拖沓,每天早晚的广播一直重复,然后就是战旗玩法普遍有争议(我个人还挺喜欢玩的,因人而异吧)有几条线过于史,神人台词神人剧情,有一种苍月一个聪明人看一群傻子的美感。每条线的人物待遇差别过大,领袖魅力线小希被活活打死,大多数线怠美和凶鸟都活不了,青春篇对于苍月来说就是没有爱也没有青春的旅程,唯一全员存活SF结局解锁需要把好几条史线都赤一遍 总结:整体来讲很喜欢这部游戏,光一个真相大白篇我觉得它值得一玩,为了弹丸2×2能早点出建议还是买一份(
I finally finished the entire game so i can write my review now. I really loved this game. (Most of) the characters are very lovable and there are some really interesting endings and routes!!! However, you have to be a little weird to like this game, so it's not for everyone. If you dont like repetitiveness and offputting themes, you will probably not like it. Since there are so many routes and endings, there are bound to be ones you won't like at all, so you honestly just need to be able to get through those lmao. Anyway. Amazing game!!!
什么希望啊... 真的不是...绝望吗?
Best way I've seen a game do multiple endings. For a while, the game doesn't let you make any decisions to change the story, but once it does it makes complete sense and is amazing.
The game is extremely enjoyable, both in terms of the gameplay and the story. I do have one issue, though: the game becomes hardly challenging once you start maxing out your characters and potions. However, this isn’t really a problem for me since I can simply skip the battles and focus on enjoying the story. I came into this game after playing Danganronpa, and it definitely exceeded my expectations. Hopefully, 2X2 will be able to live up to this game, although that’ll be a difficult task considering how good this game is.
