When Sakaido wakes up in what he assumed would be Asukai Kiki’s Id Well, Kaeru’s dead body is nowhere to be found. Instead, he’s flanked by his very much alive wife and daughter. He remembers he isn’t the Brilliant Detective Sakaido at all, but Narihisago Akihito.
He hugs his family, who react as if he’s acting weird. But as far as Akihito is concerned, if being able to go back in time, fix what broke, and protect those who mattered most to him is “losing it”, then he doesn’t want to have it.
Without dwelling too much about what this reality is, Aki starts by paying a visit to the Challenger. Since this is before Muku was murdered, no one in this world has caught on to his depravities, except Aki, who comes in with outside knowledge from this reality’s version of the future.
Instead of rushing into Challenger’s house in a revenging rage, gun blazing, he challenges the Challenger to a “fair and square” fight, for which the killer is obviously more than game. Aki gets the absolute shit kicked out of him, but he manages to get the upper hand just as Momoki, the only backup he requested, arrives.
With the Challenger in custody, Aki directs Momoki to check out the basement, where a still-living victim sat bleeding in the “arena”. The woman turns out to be Asukai Kiki, and when Aki visits her hospital room, he’s perplexed by the fact she looks just like Kaeru. Kiki tells him how her thoughts have a way of broadcasting themselves to people around her.
Turns out Aki is in Kiki’s dream, because not only is there no sign of her injuries in the waking world (or whatever it is), but in this dream world of hers, serial killers like the Challenger come every night to kill her, with each night designated for a certain killer.
Aki soon wakes in his own bed with his worried wife and daughter by his side, while Momoki informs him the incident with the Challenger is being considered self-defense (a welcome change from the premeditated murder charge of his first “go-round”). He meets with Kiki—for real, this time—but can’t get her, an inhabitant of this “reality”, to explain what the reality is.
What she can tell him is that the person who has been letting one killer after another into her unconscious dreams every night matches the description of one John Walker: top hat, tails, and cane. This not-quite-Id Well-within-an-Id Well scenario created as many questions as it answered, and Hondomachi is still AWOL, but I am nevertheless deeply intrigued.
