@Hounder probably some futuristic feature of those modules to morph into the characteristics of the core. The replacement module for Dahlia when she first died way in the early chapters also changed appearance, and even so everybody recognized her when she came back in a different body.
@Hounder pretty sure the physical appearance change is real. when dahlia changed bodies around like 28 or somthing (well not really change bodies but a android took her AI) its appearance changed from a the original to her. also i feel that dahlia gets to choose when to switch so if she notices asebi acting strange or notices an order being made she can force the switch
Dunno how I feel about that... At least they change their appearance when switching... >,> (I do find it stupidly silly that they had to switch to save someone... lol)
Her status as an A-grade citizen does not allow her to override Asebi's master's command. And while she's a proficient mechanic, she's no genius among the Waldecians, so I don't expect her to be able to hack into the modules, especially if she wants Asebi's personality intact.

You aint the only one. Either Dahlia cannot autocontrol a fish on the spot, the fish is too large or she is unable to do it now that her core is in Asebi's body. Even then, I'm just glad to see Dahlia back to normal size.
