Twenty-five years before Catastrophe, Sakae had attended First Shibuya High School. The Hīragi's wore him down until he was completely submissive to them.

Book 1
Guren remembers how on the day he had last seen Mahiru, he came home bloody and bruised as he was beaten by men from the Hīragi family who came to get Mahiru. He remembers the look of sorrow on his father's face and how he hugged Guren. However, after that, he went to the Hīragi compound to apologize.

Book 2
After Guren's interrogation, Kureto mentions to him that his father had come to the Hīragi compound to ask that Guren be let go. They took him into custody and questioned him and he told them everything that Guren did such as receiving an invitation from the Thousand Nights but not coming to an decision and that this war started while he was considering his answer. He also tells Guren that his father is very weak as he broke down and talked five hours before he did but then his heart gave out in the end. He assures Guren that his father isn't dead as they revived him and sent him home.

Several days later, Guren calls him while he's playing hooky. He asks if Sakae if he's okay after what happened yesterday and he says that he fine. Moving on from that, he says that he needs to tell Guren something important.

He tells him that during the six o'clock news, a story is going to break and it's something that the Thousand Nights have been trying to squash. While on the phone, Guren watches the news and it shows the story: the animals at Tokyo's Ueno Zoo have been killed by an unknown suspect or suspects. Sakae says it's being told that someone spread poison throughout the zoo and supposedly as the poison might still be there, the authorities have sealed everything within a half-mile radius. When Guren asks why this is important, Sakae says that that the story actually broke in the middle of the night, at around two in the morning but, the Thousand Nights have been keeping it under wraps.

Guren asks him if he wants him (Guren) to figure out why but Sakae says that's up to him as he figured this would be of interest to Guren. He becomes silent for a moment before telling Guren to not do anything too risky as it won't do anyone good if he get's himself killed. He adds that he's sure that Guren will do be fine since to him, Guren is smarter that him. Guren jokingly answers that if he was that smart, he wouldn't be caring about gaining more power.
