The Crown Prince and biological twin brother of Pacifica, Forsythe prioritizes his people's welfare above all else, in stark contrast to his father, the King. He abhors the unnecessary bloodshed directed at eliminating the Scrapped Princess. This stance, along with his physical resemblance to his mother and Pacifica, often puts him at odds with the King. When Baroness Bailaha introduced Christopher Armalite as her adopted son, Forsythe and Christopher formed a close friendship.
Forsythe frequently found himself torn between his duties to his people and his desire to protect Pacifica, his long-lost younger sister. The Mauser Cardinal urges Forsythe to serve as an Envoy of God, focusing on the greater good of his people. Later, Forsythe arranges a meeting with Pacifica to finally meet his twin. After a brief and awkward conversation, he embraces her, apologizes, and then stabs her in the back. Immediately after, he pulls the sword free and impales himself, choosing to die alongside his sister as atonement for his actions.
However, when Pacifica 'destroys' Providence, Forsythe is revived from death. In the final episode, Christopher reveals that Forsythe will soon be crowned the new King.
