Gai zieht eine neue Mission ans Land. Doch bevor Shu offiziell dem Team beitreten kann, muss er zuerst sein Kampftalent unter Beweis stellen.
Shu arrives at the Undertakers Headquarters at Roppongi Fort where Gai introduces him to the Undertakers and plans to hold a trial for Shu before he can officially join them. Gai assigns Ayase as Shu's instructor while he leads a mission to take over "Leukocyte". Ayase dislikes Shu but is only training him because it was Gai's orders and Shu has to pass the trial as Ayase has his pen, unaware it's a transmitter but she will only give it back after passing the trial. After some hard training, Shu encounters Inori, telling her that he joined the Undertakers because of her and asks her if she will join him if he wanted to leave the Undertakers. But Inori tells him she won't because Gai gave her a life and purpose and claims Gai told her to use his feelings for her to join Undertakers before entering Gai's room. Dejected, Shu runs away and bumps into Ayase, who consoles Shu and gives him some encouragement for tomorrow's trial. Unknown to both of them, despite what it seems, Inori is actually giving Gai a blood transfusion. On the day of trial, Shu has a mock battle with Ayase's Steiner where if he gets past Steiner and into the vehicle behind it, he will pass the trial. Shu succeeds the task after using Arugo's Void to blind Steiner and get into the vehicle where Ayase and the Undertakers congratulate Shu of the becoming one of them. Just as Kenji arrives, the Undertakers receives a troubling report from Tsugumi. Gai earlier led a team to intercept the arrival of mercenaries and Endlaves at an airport but their position was shoot by Leukocyte, an orbital satellite laser.
Shuu s'est décidé à accompagner les Croque-morts mais pas à les rejoindre. Il se demande encore s'il les dénoncera au GHQ avec le transmetteur que le commandant Segai lui a remis. Pour les Croque-morts, la victoire de la veille ne sonne pas l'heure de la fête mais celle du prochain plan au cours duquel Shuu se révélera être la pièce maîtresse. Gai confie à la pilote d'Endlave Ayase l'entraînement du lycéen afin que celui-ci puisse participer activement...
ＧＨＱの収容所を脱したシュウは、ガイを逮捕したいというセガイから、密かに渡された発信機を胸に、彼らのアジトに足を踏み入れる。
そこでシュウは、葬儀社の一大作戦である“ルーカサイト”攻略のため、メンバー達から戦闘訓練を受けることになる。
振り返ることなく皆を率いるガイ、そして彼を信じてついていく部下達。彼らを理解できず、ガイへの不満は募るばかり。
さらに唯一信じられる存在であった、いのりの真実を目の当たりにし、シュウの心は深く傷つく。
そして訓練の締めくくりに、綾瀬と模擬戦闘を行うことになるシュウ。見事勝利したシュウを、葬儀社の面々は仲間として迎えいれてくれる。
彼の胸に沸き起こる、認められたという達成感。だがその時事態は急転する。
――見えない檻“ルーカサイト”の脅威が、任務に出ていたガイの頭上に襲いかかり……
슈는 얼떨결에 따라와 얼떨결에 장의사 멤버 후보생이 되어버리고 만다.
저질체력을 부여잡고 악마교관 아야세의 호통을 들으며 숨이 넘어갈듯 말듯 생고생하기를 며칠.
그런데 최종테스트 전날 밤, 우연히 이노리와 대화를 나누게 되었다.
Gai lleva a cabo una nueva misión y la persona clave para esa misión es Shu, pero para eso Shu debe unirse al equipo oficialmente, ganándole en un simulacro de batalla a Endlave Ayase. Shu podrá concentrare y pasar esa gran prueba? ya que sus sentimientos sobre Inori son aplastados por las palabras que le dice Inori a Shu
集前往了葬儀社的基地，但卻連休息的時間都沒有，立刻為了實行白血球作戰計畫展開基礎訓練，集也從中再次體會到葬儀社成員高強的戰鬥力。面對問他為何來到這裡的祈，集原本想對她表白自己的心意，卻因為她的回答而大受打擊。模擬戰即將開始，集能被葬儀社認同，成為他們的一份子嗎？
Shu evade dalla prigione della GHQ. Arrivato al nascondiglio di Gai, si allena indossando un trasmettitore che Segai, deciso ad arrestare Gai, gli ha dato di nascosto.
Shu ucieka z więzienia GHQ i trenuje w kryjówce Gaiego. Ma przy sobie przekaźnik otrzymany od Segaia, który zamierza aresztować Gaiego.
