This episode picks up the pace again and we are bombarded with new facts and situations. Narihisago wakes up in the 2nd level well of Kiki Asukai, which exists in both the well of Narihisago and Momoki. In this well Narihisago remembers everything and discovers he is in his world, back before the murder of his family. During his adventures in this world he saves Kiki Asukai, who seems to be a key to this whole mystery. I will not spoil things for anyone so I will not describe what occurs, but a few points which are puzzling. When Narihisago was sent back he was only given 10 minutes, yet after 10 minutes he is not yanked back. Kiki Asukai is in her own well, which means she is permanently lost in this well, according to an earlier episode. I am guessing this well is so detailed because its live, rather than based on a few random partials collected in a specific location. Thus its not representing any strong emotion, rather it represents standard emotions. Both the facts could explain why this well is so strange. My final point is Narihisago was supposed to save Hondomachi, yet he makes no effort in this direction.
Great series and I can't wait to find out what happens.
