Spoilers.
Episode 31 - some questions were answered.
Shin was heroic(some people would say foolhardy) this episode. But it's hard to get close to 001..
Belt-san is afraid that Shin will get defeated/killed by 001, so they quarreled.
I really like the pretty scenery in the scene where the Roidmude met under the night sakura.
Each Roidmude has obtained various human emotions.
001's motive is to evolve further into the super evolved form(mentioned by Heart during Chase's modification), and to create another Global Freeze.
"By growing this strong emotion further, and passing the limits, we will be able to reach our last evolution. When that time comes, we will start the second Global Freeze!"
001 is planning to use Shin as the 'key' in order to surpass his limits so as to evolve...he advises Heart to find a 'key' to help his evolution too.
So 001 has been Makage for over 12 years now...and now we know why Shin's father, Eisuke, was killed. The memory alteration does not affect certain types of people.
32 looks to be very tough on Shin as well...
My speculation(based on a picture on the official site) is that 001 is conducting human experimentation. :O_O:
Edit:
On a side note...Makage's actor, Horiuchi Masami, seems to be enjoying this evil role very much, looking at his tweets
