It is the time for the Festival of Lanterns where Japanese people honor their dead. Hikari wonders about death and it's reality is presented to her when a cricket she's been keeping dies. Jennifer reports on the ED (Extended Definition) phenomena to her superiors. They wonder about what is to happen with a new extinction on the way, something that's happened seven times before in Earth's history. Hikari is plagued by dreams in which her "dark" half wonders why she's fraternizing with those she's to destroy.
