Wew, finally I managed to finish this game. Really, really beyond my expectations (so should I be happy or disappointed ? lol)

Just my speculation...

Spoiler for ending:

I haven't read all the spoilers on this forum. Probably, just probably, my stupid thought.
Considering on "YUKIDOH’s Plan’s Failure End", I guess we've been played this game on SPHIA's arc as ENOMOTO ??? I thought that probably on 18th July, 2011, both Enomoto and Yukidoh was exchange consciousness.
Thus, it make senses when "Enomoto 2011" (actually Yukidoh) called "Yukidoh 2011" (actually Enomoto) with "Enomoto"
Then, the protagonist "Yukidoh 2011" referring to (and finally killed him) is Enomoto's consciousness, trapped on Yukidoh's body
