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!

this part is written after getting 100/100 endings. some of this game is truly amazing. certain routes had me engaged throughout and struggling to put the controller down. the peaks of the 2nd Scenario route are in contention for one of my favourite VN stories of all time. at the same time, you get stuff like the box of blessings route that I put down so many times bc it truly was mind-numbing. Most routes are generally good, but many feel tonally and narratively dissonant from the rest (likely a result of both rushing and the writers differing between routes). below is my personal ranking of the routes. [wip] == original review below. overall, great game. gameplay is good but gets old after a while (mostly just from game length and lack of variety). the game doesn't do enough to change things up, so every fight kinda feels the same (especially once everyone's positions stop changing, e.g. the twins are always defending the east, takumi and nozomi are always defending south, etc etc). the game seems aware of this though since you can start skipping fights you've already done in another route, so there's that. at that point, the game becomes essentially strictly just a visual novel. you can also trivialize the game by hyper-investing into Tsubasa from day 1 (with last yell support from party) and just mowing down every single wave. i've heard this works for tons of characters too, but her not dealing with fatigue makes it so easy. story is hit-or-miss. when it hits, it really is very engaging and unique. at other times, it just goes on wayy too long, or the story branch just never gets interesting. to be fair, you can skip most routes, but some are required for one of the game's most conclusive endings. luckily, these "required" routes aren't the worst, but there's a pretty noteworthy example of a mandatory one that is essentially complete nonsense (the box of calamities route's ritual ending). of the routes i've done so far (roughly 65/100), there are only a few i didn't enjoy (romance and some branches of other routes) and only a few i thought were exceptional. still don't know everything about the lore, so i wont get into that
One of the most incredible and most impactful games I've ever played, my favorite story of the decade.
终于想起来写个评论。首发买的,没啥意思,剧情水的要死,很多线甚至直接让男主睡个几十天,真没必要非要为了“百日”这盘醋去强行拉时长。大部分线男主一直吃瘪,憋屈的要死,谁让男主只是一个喜欢睡觉的高中生呢。真相大白线的结局甚至不太能差强人意,全员存活(sf)线要经过几十个小时又臭又长的大奋线,味同嚼蜡,我现在的时长是刚解锁sf线玩了大概十几二十天的,好不容易到了sf看见窝囊的男主和一上来就人身攻击的比留子(好像是这个名字)就一点继续玩的欲望都没有。 人设方面除了男主,那对神人兄妹我真受不了,自私自利一点共情能力没有男主还惯着哄着他们。小胖窝囊的要死。女主我想了一会硬是没想到有啥能说的,太没特色也是一种特色吧。我最喜欢的角色还是地雷妹,其次是对面的女将军和伊娃,再剩下的都没啥印象了。不如弹丸论破任一作一根
This game altered my brain chemistry in ways I cannot describe.
你是誰?請支持百日戰紀
i love all these characters like theyre my children
It is a good game for those who like Danganronpa. Strategy part is fun as well.
There were a couple of underwhelming routes, some plotholes here and there, as well as combat overall felt lackluster in terms of difficulty (there honestly could've been some mechanic that made encounters more difficult based on the amounts of *clears* you had in your savefile), but overall the game was great, well-worth the cost and time. 100% completed and very much looking forward to any kind of new content it might have!
I killed myself and it proceeded to reveal every ending in the game
best game ever
