Though Ves did not spend as many days on optimizing the Ghost Project as Gloriana and Master Benedict, he did not need to make as many changes either.
This was because the Ghost Project did not share as many similarities with the Dullahan Project in relation to his design philosophy.
The Dullahan Project's defining feature was the first real implementation of the Carmine System.
It made a lot of sense to bind Venerable Jannzi to an expert mech that reminded her a lot of her previous machine.
Ves could not apply the same argument for Venerable Zimro Belson.
As an expert pilot who had only emerged fairly recently, Venerable Zimro had no affection to any specific mech or mech design. The stealth mechs he piloted in the past were third-party products that the Black Cats procured from the mech market. None of them served as a viable basis for a Blood Pact.
