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!

It's like Fire Emblem. Not because it's a SRPG, but because you can bang your sister.
gud gam
I've been 120 hours in, and it's still a Prologue LOL
一般剧情都是划水的,又臭又长,只有那条真相线的故事从逻辑到结局是流畅的,把其他的都砍掉直接封神,你都知道真相了就不能和敌人好好沟通吗,你怎么这么自私,焯!
fun
id rather eat bums with snakes than crumbs with steaks

我是谁?支持百日战纪。
no game was ever more perfectly made for mentally unsound perverts
The Hundred Line has become one of my favorite games, if not since I started playing perhaps 3 routes in. That said, now that I have completed everything and have nothing else to do but to wait for the sequel and recommend the game to friends, here are some routes I would like to see for The Two Hundred Line: [spoiler] - Kako's detective adventures ft. Takumi as her assistant. The mysteries being solved should be banal and sort of comedic. [/spoiler] [spoiler] - Romance route featuring Gaku and Takemaru. Optionally Shouma or Moko as well. NO Eito NO Yugamu. They have enough content already. [/spoiler] [spoiler] - Commander route(s). I would like to see their faces. Maybe it could be Takumi's turn to be lobotomized instead of Eva. [/spoiler] [spoiler] - At least 3 more routes where nothing happens and Takumi just sleeps for 30 days at a time. [/spoiler] [spoiler] - Serial Battles 2. [/spoiler]
