I have found the breakable part and captured (and uploaded) a screen shot of it. Note the exposed blue parts in its "shoulder armor" next to the core

I used the hannibal charge spear (not upgraded), 3rd blood art on the 4th page of charge spear blood arts (I have no idea what it's called but its a aerial square attack that makes a X slash) and I used 1 shot of the famed (and hated) meteor bullet (the weaker version, not the fully powered one that ends missions in mere minutes). I'm not sure if it was just my imagination but while fighting either me or Ciel seemed to do orange damage instead of green damage? I honestly have no idea since I was sleepy at the time of the fight.

Strategy to breaking that part? - I only used ground square combos, aerial square combos (with the aformentioned blood art), charge glides (done in the air, aimed at the chest) and 1 (weaker) meteor bullet shot.
