Ves and Gloriana had reached the highest degree of cooperation. No matter how many disagreements they might have over the course of their daily lives, they were still a married couple. They genuinely loved each other.

Ketis was a long-time Larkinson mech designer and also cooperated well with the married couple. Her design philosophy along with the addition of Sharpie's extraordinary willpower allowed her to forge much better swords than anyone else in the Larkinson Clan and arguably beyond!
