Despite Saki’s hospitality in bringing Kotoko into her home to tend to her minor wounds and serving her coffee, it doesn’t take long for pleasantries to cease and for the barbs to start flying.
Saki is dubious that Kotoko and Kurou are really dating, and isn’t convinced by Kotoko’s obviously forced “couple” photos. Kotoko eventually reveals that Kurou disappeared a week ago and hasn’t answered her calls or texts—more fuel for Saki’s “he doesn’t like you” fire.
After Kotoko takes her leave (on the shoulder of an awesome giant skeleton!) Saki wastes no time diving into the internet to research the life of Nanase Karin, a well-endowed beauty who could also boast a sharp intellect.
She gained a flame-throwing lead role on a live-action drama (the OP for which we see in its entirety) and her fame grew, but her father, whom it’s believed she resented after he quit working, died under mysterious consequences.
An unscrupulous tabloid put forth the theory that she murdered her father to get him out of the picture (and collect on his life insurance), Karin took a kind of sabbatical. But the day after a bad storm an eyewitness found a body buried under fallen steel beams.
The head and face were completely pulverized, but the rest of the body, clothes, belongings all pointed to Karin as the victim of the accident. Some time after that the legend of a vengeful spirit grew in the town.
Both Saki and Kotoko arrive at the same point in their respective investigations, but only Saki has the benefit of police records and resources to support their case. The idea is planted in both their heads that there’s more to this Steel Lady Nanase than has been covered by news, reports, and the internet.
My take? The absence of her face could mean the body was that of Karin’s older (and similar-looking) sister, whose life Karin then took over…but that’s just one of several theories rattling around.
Before Kotoko and Saki meet to put their heads together (and make no mistake, Kotoko relishes being able to freak Saki out with youkai), Kotoko is informed that Steel Lady Nanase has reappeared, and finds Kurou dueling with her.
