some OL friend of mine mentioned about some things and I re-read chapter one till the newest chapter...and you know?...I HATE NYMPH ACTION TO PREVENT IKAROS TALK, MORE!!
That little maggot...she have ability to hack even Angeloid including herself (memory must be easier)
, she can hack Tomoki mind so it's disconnected from Synapse Memory Deleting Systems and keep his memory intact.
Bastard! hope CHAOS return soon and rip off her wings again!
but we get other clue
...this chapter explaining what happened to Daidalos and Tomoki pairing in the past. Now, may be Tomoki will have two dream, about him self with Daidalos, and with Hiyori
For who still wondering why Sugata can enter Synapse via Tomoki dream without Nymph, it's because the Dream Dive Game device still in his tent and can be set to automatically reset after some period of time, like a Stop Watch
