Oshtor

In his "Oshtor" personality, he's very stoic, professional, courageous, and dignified. He is someone who'll use underhanded tricks to win if necessary, but can be honorable enough to engage in something like a duel if he has a respectable opponent. He speaks in a dignified and fairly formal manner, though also in a somewhat friendly tone too (although of course not really the friendly part when on the battlefield).

In his "Ukon" personality he is loud, cheery, the very opposite of appearing dignified. He has a very warm and casual form of speech, and just seems the kinda guy you'd want to share a drink with. However even in his Ukon form he can act professionally when it fits the current situation.

Oshtor is Yamato's general of the right, where Yamato is a fictional country in the story Utawarerumono. He's revered by many of the people of Yamato, as a stoic, composed, and compassionate leader that defends Yamato.

But at the same time is another side of Oshtor. He occasionally takes on the identity "Ukon", an undercover identity he uses to help the Yamato kingdom in ways he can't as Yamato's Imperial Guard. Unlike his "Oshtor" persona, Ukon is a lot more free-spirited, speaks much more casually, less stoic and a bit more chummy/friendly, and speaks in a much more casual tone.

It is said that Oshtor doesn't know which one represents the "real" him, and it's probably a mix of both. Although, it is said that his "Ukon" persona aligns more with what he admired within his own father, for how "Ukon" is more friendly with the people and not raised to a higher pedastal.

Note that very few know about his alternate identity, and he tries to keep it a secret because otherwise what's the point of a secret identity?

Utawarerumono is a story taking place in a world where humans have gone extinct and instead new species similar to humans have risen, with the only difference being that they are somewhat furries, meaning they have animal ears and tails.

The Mikado of Yamato is hailed as the creator of these species and has eight generals protecting Yamato. These are: Vurai (powerful warrior and akuruturaka wielder), Raiko (master tactician), Soyankekur the Mariner, Ozen the Harvester, Tokufasa (jack of all trades), Woshis (mediator between generals), Dekopompo (ugly bum), and Munechika (master of defense).

He's on good terms with Munechika and on bad terms with Dekopompo (most generals are cause he sucks) and on even worse terms with Vurai. Oshtor defeated Vurai in a duel before, though Oshtor used cunning and "dirty" tactics rather than brute strength to win. Also Oshtor spared him once, which Vurai sees as an insult.

There is also the Imperial Guard of the Right, Mikazuchi. They seem to get along pretty well, as Oshtor disguising himself as Ukon also gave the idea to Mikazuchi that he should do the same so that he could observe the people better.

Oshtor is a wielder of the akuruturaka, a mask that turns the user into a powerful beast which grants immense power but takes from the user's life force. He is also very strong as a regular warrior too. He's a somewhat decent tactician/strategist, especially when it comes to handling political conflicts, and he's able to be crafty with his plans, though he's by no means the best.

Nekone is his sister and someone very gifted intellectually. Oshtor likes to dote on Nekone, though he's much more restrained in his "Oshtor" persona. In his "Ukon" persona he is much more doting and likes to try things such as forcing Nekone to sit in his lap. Nekone tries to act like she hates it and doesn't like how unrefined Oshtor acts in his "Ukon" persona, but it's clear she really loves him.

Haku is the protagonist of the Utawarerumono games, and is a "lazy hard-worker" and crafty, someone who constantly tries to get out of work but will do the best he can if it's someone he cares about or if not doing it will make him feel guilty. They met when Oshtor was using his "Ukon" identity and Haku proved himself a resourceful and crafty tactician, so Oshtor hired him along with some others (such as Kuon who's kinda like Haku's guardian and Kiwru who's Oshtor's bro in law) to do tasks that he himself is unable to do, like deliver supplies to a neighboring country when he's tasked with guarding Yamato's capital. Oshtor takes a liking to Haku and trusts him wholeheartedly, and they quickly become best friends. It is unknown why Oshtor trusts him so easily, but it may be because it reminds him of someone he knew before.

Oshtor also interacts with the princess and future successor of Yamato, Anju. He is one of few who actually entertains Anju and whom she has fun with, though Anju feels lonely when he's not with her so sometimes he tags along Haku's group.

Oshtor is someone who tries to be a guiding pillar for the people of Yamato and do his best to guide them, and this means he can resort to using underhanded tactics using politics to get what he needs to done.

For example, he cooperated with some bandits to expose Dekopompo's illegal trades, and also framed a different group of bandits so that the bandits he allied with wouldn't be executed. Furthermore, in a duel with Vurai, he feigned being too weakened to counterattack to get the opponent to lower his guard, and then hit Vurai with a counterattack he was sneakily preparing.

Also as for another reason why Oshtor created a "Ukon" persona, he created it so that he can do some tasks required of him in peace. For example, because of how "Oshtor" is so widely regarding, he can't just observe the people when he is in his "Oshtor" identity as he'll attract the eyes of the citizens, so he adopts the identity of "Ukon" so that he can patrol the streets of Yamato and sneak around without anyone following him. Another subtler reason why he chose to have an alternate "Ukon" personality was because it was probably a lot of pressure to have to bottle up his true nature as "Oshtor" to look good publicly, so "Ukon" as an outlet to act like he always wanted to.

He is heavily inspired by his father who was said to be a greater leader and strives to be like him, which is another reason why he likes using his "Ukon" identity.
