Bosse

 (ボッス, Bossu) is a character in Ousama Ranking and its anime adaption. He was the first king of the Bosse Kingdom and the father of Bojji and Daida. He was ranked #7 in the world, and widely acknowledged as the strongest man in the world.

Appearance
Bosse was a towering adult giant with black eyes, shaggy brown hair, a matching shaggy brown beard, and a very stern face. He was nearly three times the height of most adult humans, and had prominent scars crisscrossing his very muscular body.

He has since been forcibly reincarnated into the body of his second son, Daida.

Personality
Bosse is primarily shown in flashback, where he is depicted as a man of few words and overwhelming physical power. As a younger man Bosse was truly obsessed with gaining strength, and adventured across the world to do so. As an older man, and the strongest being on earth, he became a true stoic, harboring deep secrets about his past from all around him.

Though his relationship with most of the cast is never shown, Bosse does appear to appreciate those around him. He first acknowledged Bebin for saving the life of a young snake, and it's suggested he had a cordial but friendly relationship with his second wife and son, Hilling and Daida.

Before the death of his original body Bosse professed a deep affection for Bojji, seemingly stemming from his deep love of his first wife, Sheena.

Bosse shares his deepest relationship with Miranjo, who is something of a surrogate daughter to him. He seems to feel a profound responsibility for her, or possibly a profound debt to her, to the point where Bosse was willing to allow her plotting to go largely unchallenged for years.

Plot
Bosse was originally an adventurer of unknown origin. Obsessed with becoming stronger, Bosse traveled far and wide to find new challenges for himself, eventually finding his way to the Houma Kingdom, a land full of mages whose power could rival the Gods. Bosse fought his first and seemingly only duel with Miranjo's father, narrowly killing him but sustaining grievous injuries himself. He was nursed back to health by Miranjo's mother, who bore him no grudge. Over time Bosse developed a deep affection for the young Miranjo, and became an ally to the Houma people in their battle against the Gods.

Unfortunately the Houma kingdom would be betrayed by another ally, the Gyakuza Kingdom, and most of its people slaughtered in a surprise attack by the Gods. Miranjo and her mother survived, but the mother was quickly killed by opportunistic Gyakuza, who then tortured and mutilated Miranjo. Bosse discovered this after returning from the warfront, and in his grief he slaughtered an entire village of Gyakuza, taking their remains to a local physician so their bodies could be used to restore his young friend.

After restoring Miranjo, Bosse resumed his wandering lifestyle, now with his young friend in tow. The two traveled far and wide, but eventually Bosse began to feel the limits of his natural strength. Wanting to assist her savior, Miranjo told Bosse of a demon who could enhance his power. The demon confirmed this, with the caveat that it could not create strength from nothing, but that it could steal strength from a relative. This lead to Bosse's fateful bargain with the demon, to steal his future son's power and add it to his own.

Shortly after his deal with the demon, Miranjo informed Bosse of a notorious giantess adventurer, Sheena. Though he initially courted Sheena to fulfill his bargain, it appears Bosse slowly came to love the giantess. Once Sheena gave birth to Bojji the bargain took effect, and Bosse gained the power of another giant, becoming the strongest being in the world. However, it was a bittersweet moment for Bosse, as he saw his newborn son he finally came to appreciate the implications of what he had done. In penitence, Bosse declared he would wander no longer, and founded the Bosse Kingdom on the site of Bojji's birth, so that he could defend and provide for his new family.

Bosse's reign as a king is largely not shown. He ruled for roughly a decade, and in that time was deemed the 7th ranked king in the world. Bosse's whereabouts or actions during Miranjo's first attempted coup are unknown, but it's hinted that he arrived at the castle after Sheena's death.

After roughly a decade of rule Bosse became afflicted with a mysterious illness, one that slowly killed him over an extended period. He died in his bed, surrounded by his family and members of his court. Upon his death the demon appeared again, cackling at the gathered mourners before disappearing.

In the days after Bosse's death he was forcibly resurrected by Miranjo, who restored his soul to Daida's body. Since then Bosse has been an enigmatic presence at court, aware of Miranjo's plotting and running his own plots in turn, but never directly confronting her out of a strange sense of obligation.

After the monstrous Ouken slayed most of the Bosse Kingdom's warriors, Bosse finally stepped in, repeatedly crushing the immortal and encasing his regenerating body in a massive boulder, trapping a wailing Ouken in a stone prison.

Bosse then confronted his son Bojji, unwilling to stand aside or give up Daida's body. Though it was an epic clash, Bosse failed to inflict even one hit on his son, and indeed Bojji managed to destroy Bosse's signature club.

Satisfied with his son's growth, Bosse stepped away from the fight and instead spoke to Miranjo, laying bare his true wishes for the two of them. At length, Miranjo agreed, and the two gave up their mortal forms, their souls drifting upward through the sky. Bosse's soul faded into the ether, finally and truly dead.

Supergiant Strength
Bosse was born a giant, and therefore already many times more powerful than the average human. After making a bargain with a devil he gained all the future strength and power of his first son, Bojji. As a result Bosse became exponentially more powerful than even other giants, and was the strongest single entity in the entire world.

His strength is so great that Bosse can even crush a large wooden club into a pure, uncut diamond.
