from what i'm reading, each day has been produced by a different member. so, each day has a different celestial theme. like Junno has the Moon. Jin will have Mars & Kame is Mercury. totally blanking out on TUN. D: KOKI HAS SUN....i think.
the true difference is that whoever produces that specific day, chooses about 3 older songs to add on to the solidified setlist. the intro (which is RESCUE), encore (Peaceful days & SHE SAID...), etc. have been the same.
but i'm not entirely sure how the rest of the concert days will be like...since there's only like 6 members & 13 days...so are they going to produce 2 days each? and like 1 group day? IDKLOL.
& man, if JE releases like a mega-version DVD set will all days in it. i would honestly consider selling a kidney just to get it. maybe i can sell some of my eggs.
yes, i do realize i'm crazy. i have an active imagination.
