Bo Kingdom

The Bo Kingdom was a prosperous overworld kingdom in the universe of Ousama Ranking.

Though only shown briefly, the Bo Kingdom figures heavily into the origins of many characters. It was the adopted home of the Shadow Clan, Kage's birthplace, and is strongly implied to be Kingbo's lost kingdom.

History
While not much is known about the Kingdom of Bo, it appears to be a land-locked, fertile region containing plains and hills. Their capital city is also near an enormous woodland called the Toxic Forest.

The Bo Kingdom is the original home of the Shadow clan, which directly served the King of Bo as his private assassins. The Shadow clan appeared to live among the rest of the citizens of Bo openly, though not much is known of their circumstances.

At some point in the past someone attempted to assassinate the King of Bo. The Shadow clan was immediately blamed, and they were quickly persecuted by the ruling class of the kingdom. Members of the Light clan, a rival to the Shadow clan, helped hunt down and execute every member in a vicious pogrom. A young Kage fled the kingdom during this period, and is currently the only known survivor of the Shadow clan.

Kage
Formerly the home of Kage, him and his mother were forced to flee when the Light clan began their massacre of the Shadow clan. He is the only survivor.

Kage's Mother
Formerly her home and Kage's, they were forced to flee when the Light clan began their massacre of the Shadow clan. She would die trying to buy time for Kage to escape. From the familiar dialogue between her and Geslan, Kage's mother may have been a high-ranking member of the Shadow clan. She also seems to have believed Geslan was the driving force behind annihilating the Shadow clan.

King Bo
Ruler of the Kingdom of Bo, and previously the one who held the Shadow clan's loyalty until the attempt on his life.

Lord Geslan
Apparent leader of the Light clan, Geslan relished the killing of all of Kage's people, and went so far as to taunt Kage's mother and suggest they already captured Kage prior to her death. Geslan also appears to have intentionally chosen to carry Kage's mother's body (supporting the theory she was a high-ranking Shadow clan member) as she was hanging off the scabbard of his sheathed sword.

Countess Poise
A noble of the Bo Kingdom, Poise was apparently of higher rank than Lord Geslan, causing Geslan's soldiers to be exceptionally wary of the little girl. Both cunning and caring, Poise provided critical aid to Kage, allowing him to hide in her stuffed spider while being pursued by Geslan's forces. Her manservant then provided further instructions to Kage, giving him advice on how to pass through the Toxic Forest and escape the Bo Kingdom. Kage remembers both Poise and her servant fondly.

Poise is not seen again until the volume 13 bonus chapter, "Poise of the Toxic Forest." Set in the present day, Poise is shown to have grown considerably and taken on a role as the guardian of the Toxic Forest. This has set her at odds with the nearby human settlements, as the Toxic Forest is slowly spreading and causing illness.

Unnamed Servant
Servant to Countess Poise, he was able to assist her in the ruse when Kage became grief-stricken at seeing his mother, yelling at the soldiers to leave and stop upsetting her while at the same time helping to hide Kage from their line of sight. He also gave Kage advice on where to go to get out of the Kingdom of Bo, and suggested to Poise that members of the Shadow clan are always able to pick themselves up when they fall.

Trivia
There is a popular theory that "King Bo" refers to Kingbo. This is largely due to their extremely-similar names, but also attributed to Kingbo's passing resemblance to members of the Light Clan.
