Anti-Visto Alliance is a faction formed by commanders from several kingdoms like Eliott (Elt Kingdom), Hitoha (Nanomiya Empire), and Rutimone (Noir Kingdom). Their purpose is to halt Visto's invasion and end the war.
Infamous for his interest in bedding beautiful women, Jin was also a genius military commander of the Kagura Fiefdom. He managed to halt Visto's invasion by disrupting their back lines. However, Kagura eventually fell due to treachery. Since then, he's been in hiding, waiting for a chance to strike back at Visto.
Yae was Jin's second in command in the Kagura army, as well as maid. She's excellent in martial arts and espionage, but terrible at any type of household chores despite being a maid. She unconditionally loves Jin.
Eliott is the supreme commander of Elt Kingdom's army, following the demise of her father, General Albarl. She was chosen due to her excellent skills, as well as the fame, reputation, and honor built up by her father. However, she has little actual combat experience. To save her nation, she is willing to hire Jin in exchange for her body.
Musto is the wise prime minister of Elt Kingdom. She's been taking care of Elt's foreign affairs for the last 200 years. It is unknown if she uses magic to keep her body from aging, or if "Musto" is a hereditary name passed down for generations.
Erunea is the queen of Elt Kingdom. She's been leading the country since her husband, the late king, died in the war. Despite being fairly ignorant of politics and war, she is very popular with her subjects and citizens.
Hitoha is the third princess of Nanomiya Empire, who is known to be proficient in martial arts. Having to endure both the disputes within her family and internal struggles, she continues to fight for the Empire's sake.
Rutimone is the princess of Noir Kingdom. Like her kingdom's reputation, Rutimone is capable at using magic. However, she hardly utilizes it because she despises fighting. The wings on her back is a magical item.
Known as one of powerhouses within the continent, Visto began to expand its territories several years prior to the game. Their invasion was met with oppositions from resisting countries, though none succeed in stopping Visto entirely.
Lydia is both princess of Visto and the commander of Northern Army. She has developed interest in both humanities and martial arts, and was made a commander because of her ability instead of her status as a princess. Instead of the harsh policies her father takes, she endorses a more peaceful approach.
Kenneth is one of Visto Army's generals, commanding the wyvern forces. She's an elf from a gentle forest tribe who ended up in the world of humans. Due to her personality, she gets taken advantage often, which results in many failures.
Serubian was initially the leader of Visto's Eastern Army. Later on, he sets off with Lydia and Kazan to suppress Elt Kingdom in the south. He acts like a faithful knight to Lydia, who also happens to be the princess of Visto.
