About
Asako was Hikiko's mother and Aiko's grandmother. Thanks to her intervention, Kanetsugu allowed Hikiko and Aiko to live at Mejiro Villa. After she died, it became apparent how much her support kept the family together, as Hikiko began breaking down more frequently and beating Aiko.
The spirit of Asako reveals to Iida and Nezumi that, after the fire, Aiko had consumed Hikiko's soul — possibly in an attempt to survive. After witnessing the two purifying the soul of Hikiko, she requests that they do the same for Aiko.
