Regarding the matter of "Kujo Hikari's murder motive," Minamoto Tamako pondered it all night, yet was still at a loss.
Why on earth would someone commit murder? Having never killed anyone, Minamoto Tamako couldn't understand it no matter how hard she tried. Unable to put herself in Kujo Hikari's shoes, she tossed and turned on her bed, not sleeping in the middle of the night, and disturbed Fushimi Roku by whispering by his bedside:
"Why? Why commit murder?"
Fushimi Roku opened his bleary eyes, momentarily mistaking her for a ghost come to claim his life. He tried to persuade her to no avail and eventually resorted to covering his ears with a pillow, stubbornly waiting until dawn.
The next morning, the fishermen were up early again, and the sounds of steam whistles and shouts came from the harbor. Without waiting for Fushimi Roku to get up, Minamoto Tamako hurriedly dressed and headed to the Sapporo Police Station, intending to ask Kujo Hikari herself.
