Some parts of this
section in IS Wiki were actually explained by Tabane herself (vol 3 pg. 187).
The interesting part is that the whole Akatsubaki's body is the same as Yukihira Type-2 (vol 3 pg 188). To illustrate this, assume Yukihira Type-2 as psycho-frame. Byaku Shiki is CCA generation MS (only the cockpit is made of psycho-frame), while Akatsubaki is Gundam Unicorn, where the entire frame is build from psycho-frame
The intriguing part: Tabane said Akatsubaki is
still incomplete (pg 189). Does this mean Akatsubaki is supposed to be evolving, and it's up to Houki to upgrade it? Or Tabane is actually building her own Akatsubaki (Banshee) using her own little sister's data obtained by sending the Golems? Hope the author didn't forget this part in vol 3 which was published in 2009
The big T was actually Tabane, not Tomino . Yeah I was rewatching CCA
