No.001

Frost Oath, a new CUB adapted by the Science Council. Its prototype is based on the centaur module, "Lindwyrm", that Rosetta left in Babylonia. The humanoid hybrid frame with its severe side effects has been modified, making it suitable as a CUB. The birth of Frost Oath also marks a new direction for CUB research.

No.002

Compared with other CUBs, Frost Oath has a stronger sense of individuality. Unlike Rosetta, who is rational and restrained, Frost Oath is more wild and unrestrained. It shows stronger enthusiasm in the open wilderness, such as snowfields or woodlands. Frost Oath has a strong sense of identity and belonging to the group, showing no mercy to enemies that violate its territory. It is bound by duty to guard its companions.

No.003

Based on the individual wishes of Rosetta and Frost Oath, Rosetta can quickly return to the battlefield in her centaur form. Although the effectiveness isn't what it once as, the cognitive load brought by this state has been drastically reduced. Echoing one of the design concepts of CUB, Frost Oath is not a disposable weapon but a long-term companion on the battlefield.
