Hondomachi’s first mission in an Id Well is no murder-of-the-week, but could be the key to everything. The Id Well in question is Narihisago Akihito’s, taken from still-strong cognition particles found at the sight where he emptied a clip into Katsuyama Denshin, the man who killed his daughter Muku.
Here, Hondomachi is not Hondomachi, but the Brilliant Detective Hijiriido Miyo, sporting a stylish twist on the classic detective coat. Following the same pattern as Sakaido, the sight of Kaeru’s body triggers the memory of who she is and what she’s here to do.
While Miyo is handcuffed to Kaeru, the fact Kaeru was killed by lightning means they were cuffed together by a third party after Kaeru died. When Miyo spots a dead Narihisago, she determines he did it to keep her safe: lightning never strikes anywhere twice here, because it’s not real lightning, flashing every nine seconds without fail.
All the other people in the well are family and people connected ti Narihisago, but Miyo manages to get them all onto safe spots to stop the killings. When Narihisago’s wife and daughter Muku wonder what’s to be done about people elsewhere getting killed, the single-minded Miyo suggests they do something about it; she’s here to solve a mystery.
Moving in nine-second spurts, Miyo eventually makes it to an operational cockpit that leads to the id well of the Challenger’s last victim, Asukai Kiki. Diving into an Id Well within an Id Well is some Inception stuff we haven’t seen from this show yet, but Miyo wastes no time taking a seat in the cockpit to see where the rabbit hole goes.
Wellside, they’re unable to extract Hondomachi, then investigators burst in led by the Chief, and Director Momoki is placed under arrest for the charge of inducing all of the 44 murders committed by the serial killers investigated. In other words, they suspect him to be the John Walker; the mole within the unit.
As Momoki is taken away, and with Tougou now in charge, Habutae cracks the number pattern of the lightning: the sequence they’ve witnessed appears in pi around the ten millionth digit. Extrapolating from there, and taking into account a strike every 9.03 seconds, he calculates that the first strike hit the number “3” 1,084 days ago, the day Muku was murdered.
The Id Well within and Id Well, as well as Miyo’s freedom to expore it without interference from Wellside, comprise exciting uncharted territory, and it’s anyone’s guess which crazy twists and turns the mystery goes from here. As for Momoki as John Walker, despite the mounting evidence, I’m not 100% convinced it’s not an elaborate frame job by the real Walker.
Narihisago seems to be, however, at least with regards to having access to Momoki’s well. He believes he’ll find answers there one way or another. Will acting director Tougou indulge his desire to solve the case? I imagine so; as he’s said himself, there’s not much else he’s still alive for.
