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!

Best time of my life (maybe)
不好玩(我玩的時候已經有跳過戰鬥), 使用了一個非常糟糕的架構: 對於時間的概念有點奇怪,玩家的回檔到底是什麼, 主角在回到過去後,對於曾經經歷過的事件依然保持住一樣態度例如不知道,或者會出現一些意外但是明明 提前知道的資訊 ,對話中出現邏輯矛盾,即使角色在某些支線遭遇重大衝擊 , 主角的態度亦都貫穿整個故事(即使之前的故事遇到任何衝擊) 遊戲的代入感對我來說是對我很重要, 卻在遊玩劇情中要我使用他的ui瘋狂跳(十個分支,還沒有問題但是多個以上,就會開始迷失 我遇到了很多次 到達這個分支的時候 ,必需要首先要完成什麼什麼分支 嚴重影響遊戲體驗, 結果就是我只能偏歷, 所有可能的問題, 更可悲的 很多分支的結果與他的問題是沒有任何關連的. 而且中間的其他"垃圾"線 (純粹指的是沒有額外資訊)的意義在是什麼 在知道其他線 需要 例如收集密碼 主角完全沒有反應, 學院有機會多人, 沒有任何溝通 做任何機器, 已經知道是入侵的真相 ,回到開頭 卻沒有表達任何事情, 反而殺人動機(防止劇透) 在殺人線 會回到過去影響自己 還沒跑完全路線 本來不想給負評的 原本想說忍著去 看了影片 ,看了結局當玩完, 結果每一次都完全不想打開遊戲甚至不想去找結局,直至半年後今天再看到忍不住,給負評
