Narumi meet Renji to talk. Renji tells Narumi that he will kill him if he sees him again, but Narumi tries to convince Renji to tell him the story between the Fourth and him. Renji starts to tell him, revealing that the Fourth and him lived together with a girl named Hison before. The two men had an agreement that neither would make a move on Hison and that both would protect her from other men. Renji tells Narumi that the Fourth used Hison as a shield in a fight against the Gotouda Group, causing her death. Renji vows revenge and tells Narumi to stay out of it. Narumi later talks with Yoshiki, who tells him a bit about the Fourth. Narumi realizes how much the Fourth cared about Renji and calls him to beg him to ask Alice for help. The Fourth later comes by the ramen shop to finally ask Alice to help him out, and he finds out that the other NEETs were already on it. Narumi confronts the Fourth about Hison, but the Fourth refuses to tell him more. He later asks Alice, who warns him that investigating may cause him to lose a friend, but he chooses to do so anyway. Narumi later finds out from Hiroaki that on the day of Hison's death, the Fourth was seen with a bleeding shoulder as well. More importantly, there were reports of another woman's voice coming from the apartment. He rushes over to the Fourth to find that the butterfly tattoo on his shoulder actually covers that scar, so he concludes that the men were actually after Hison, not the Fourth. The Fourth refuses to tell him anything, so he goes to talk with Alice again, who tells him that the Gotouda Group's leader divorced his wife right after Hison's death, which leads her to conclude that the culprit is the ex-wife. She also concludes that Hison was pregnant, due to the fact that she was stabbed in the abdomen. Alice tells Narumi that he needs to hurry and tell Renji the truth about the incident, but Narumi gets a call as he leaves that the Fourth has been attacked.

そんな折、ヨシキとの会話の中で、ふたりが交換した一番大事なモノに気付いたナルミは、四代目に連絡。

その言葉に、四代目は………。
렌지에게서 4대와 틀어진 이유를 들은 나루미는 도저히 믿을 수가 없었다. 4대가 도저히 그런 파렴치한 짓을 할 사람으로는 보이지 않았기에... 하지만 앨리스는 의뢰를 받지 않았다는 이유로 이 건에 나서지 않고 있었다.
