真曆71年，中立國吉歐爾第77區組的出現了一批可疑的轉學生。這些假轉學生其實是群來自軍事強國多瑙的特務少年。配郃著多瑙對吉歐爾的全麵侵略，他們一麵引導著本國的軍隊入侵，一麵要奪走一檯名為valvrave神祕機體。但在混亂中，2年b班的時縞遙人坐上，並啓動了這檯機體。

遙人雖神勇的以valvrave打倒了多瑙軍，但同時也死在l-艾爾伕的槍下。就在l-艾爾伕轉身走去時，遙人突然像吸血鬼一樣咬了他。沒想到這一咬，遙人進入了l-艾爾伕的身體。瞬間得到l-艾爾伕超人戰鬥能力的遙人，一麵想著變迴的方式，一麵與究真、愛奈等人一起脫逃了。

就在遙人把l-艾爾伕交給arus軍的同時，l-艾爾伕冷靜的說了幾個詞便被帶走了，而arus軍方也發現l-艾爾伕是別號”單兵旅團”，曾創下單兵消滅5000人旅部的超級特務。就在l-艾爾伕利用多瑙軍再犯的時機，不但他脫逃了，而且他之前所說的話一一應驗了。到底他的目的是什麼？

在照子的提議下，77區組獨立，並(併)成為了新生吉歐爾。這個百費待舉、全國只有兩個(箇)成人的新興國傢，大傢以學生會為架搆(構)開始重建傢園。不過，一連串的磨郃(閤)也跟著產生。為了讓大傢改變心情，並(併)讓自己在外的傢人知道他們的狀況，全校共同拍了一段影片，嚮全宇宙轉播出去了。

遙人與咲在探所77區組內部時，意外發(髮)現了除了遙人的1號機外，其他還有破損的2號機，與尚無人登錄起動的3~6號機。雖然遙人請咲不要說出去，以免有人和他一樣成為怪物。但想不到咲在吻了遙人之後就開走了4號機。到底她為什麼要這麼做？
