Daida

 (ダイダ, Daida) is a character in Ousama Ranking and its anime adaption. He is the second prince and second king of the Bosse Kingdom. He is the son of Bosse and Hilling, and the younger brother of Bojji.

Appearance
Daida is a tall boy with short blond hair and sharp blue eyes. He wears a purple doublet with white slashes down the front and a fur-trimmed neck, light purple hose, black shoes, and a small crown.

Personality
Groomed to rule since birth, Daida initially appeared to be a typical spoiled princeling, filled with jealousy and entitlement. In spite of his somewhat arrogant nature, Daida is actually a just and intelligent young man, who has slowly been matured by the tragedies that have befallen him.

Though Hilling loves him, she put enormous pressure on Daida from an early age, insisting he become as strong and capable as possible so he can succeed his father and care for his older brother. This made Daida deeply resentful of Bojji, feeling his brother was a useless presence in the kingdom. Unfortunately these hateful feelings were exacerbated by the Magic Mirror, a strange companion King Bosse had given his young son at an early age.

The Magic Mirror seemed to bring out the worst in Daida, encouraging his more destructive and arrogant behaviors, even as those around him tried to give him good counsel. This was ultimately a plot by Miranjo to gain Daida's confidence, only to betray him at a pivotal moment and resurrect King Bosse in his body.

Plot
Born with everything his brother lacked, Daida was praised and openly spoke of as Bosse's successor from a young age, even though he was the second-born. Naturally, this made Daida extremely arrogant, and he was one of the many in the kingdom who openly disparaged Bojji.

After the death of Bosse, Queen Hilling quickly took action to void Bosse's will, and install Daida as the second king of the Bosse Kingdom. Daida's reign was short-lived and characterized by back-biting cruelty. One of his first acts as king was to order the assassination of Apis, and another was to order the assassination of Bojji to consolidate his power. It's suggested that Daida's cruelty as king was the result of manipulation from the Magic Mirror, a strange artifact given to him by his father.

Daida's reign was short-lived. Within days of his coronation he was manipulated into entering the Bosse Kingdom's secret underground chambers, where he was forced to drink a potion that buried his consciousness and allowed King Bosse's soul to take control of his body.

Now trapped in a strange black void within his own body, Daida has slowly come to learn of his father's past, watching Bosse's memories unfold in the void. During this time Daida also came to learn of Miranjo, and her tragic origins.

Swordsmanship
Daida is an extremely talented swordsman, and was able to defeat the captain of a mercenary company prior to the start of the series.

Half-Giant
Daida is a giant/human hybrid, and seems to have inherited at least some of his father's strength and stature. Whether Daida has inherited other giant traits remains to be seen.

Healing Magic
Daida has inherited his mother's healing magic. While reincarnated in Daida's body, Bosse was able to make use of this magic and couple it with his own raw power to revive an entire battlefield of slain warriors.
