Ushii失井」 is one of the 12 Zodiacs from the novel Juuni Taisen. He is the Zodiac of the Ox. His real name is Eiji Kashii.


Ox is a tall and lean horned man with long dark brown hair (black in the novel) that's red on the inside. He looks to be around his late-20s to mid-30s and has dark gray eyes with dark circles beneath them. He wears a black "Traje de luces" with gold patterns embroidered onto it with a red tie. His horns are long and black, and it's unclear whether they're real or not.

Ox is presented as a stoic and levelheaded man, considered to be smart and quick witted by other warriors. He has a cold and analytical personality and looks at things with a logical outlook. He is devoted to doing the right thing and follows a simple philosophy of "deciding to do right and then doing right." Although not explicitly mentioned in the anime, he had decided to try and kill all the other fighters as a form of mercy upon discovering that there was a necromantist within the group.[2] Despite his feared reputation, Ox shows respect towards his opponents and is capable of being compassionate as shown with his past interaction with Tora, helping her out after assuming she was a lost child and trying to save her after being attacked by Usagi.[3] Throughout the novel, he is described as morose and gloomy.

Outside of battle, Ox goes out to restaurants alone due to his lack of knowledge on how to cook and also abstains from alcohol.[4]


Ushii has been a warrior since the age of 5. Most background other than the age he started as a warrior is unknown. The inscription on his saber reads Gobouken. The sword itself is nothing unusual in particular. In fact, it is a mass-produced item. However, he takes good care of it when he uses it. Although Ushii has a thin build, he has a voracious appetite. As a fighter, he tends to go for the vital spot of his opponents while using the smallest amount of movement that is necessary.[4]

Skills & Abilities

He is known as the Genius of Slaughter and a Natural Born Slayer, where he is known to stomp every enemy line on a battlefield without exception. Many accomplished fighters like Inou, Uuma, Dotsuku, and Hitsujii view him as the main threat, and most of the wager was put on him as they believed he was the most formidable fighter participating in the Juni Taisen. However, he admits to not having any sort of special ability of the likes of dragon or rabbit.[5] This is best demonstrated during his fight with Uuma who despite Ushii landing numerous blows with his sword was unable to do any kind of serious damage, something he himself admitted to.


  • Rapier - Ushii, the warrior of the ox's primary weapon with an inscription Gobouken. It was shown to be strong enough to damage Uuma and cut through steel, despite the saber itself having no special make or ability.


Juni Taisen

Ushii was one of the warriors who agreed to Monkey's peace proposal in the beginning. After the warriors spread throughout the city, Horse stumbles into him in a subway tunnel. Ushii relentlessly attacks Horse to no avail, due to Horse's arm guards, and leaves him so that they may fight again after the numbers have thinned out. Exiting the subway, Ushii encounters and immediately kills Chicken. Later on, as Sheep is deciding who he should attack, he senses Ushii coming toward the building he's hiding in. Using a bomb as a distraction, Sheep escapes and leaves a fake trail for Ushii to follow, eventually leading him to a bridge where he finds the Tiger and the reanimated corpse of Snake. Ushii cuts Snakes left arm off, his right being cut off previously by Tiger. As Ushii and Tiger prepare to fight, Snakes dismembered arms wrap around their necks and choke them, making Tiger foam alcohol at the mouth. Ushii throws his saber at the puddle of alcohol-foam, catching it - and Tiger - on fire. Tiger throws off her flaming jacket, which Ushii uses to burn the dismembered arm off his neck. In the endgame, he forced to admit defeat after Rabbit managed to restrain him by using unusual tactics, however, unexpectedly, Nezumi suddenly appeared while carrying an explosive belonging to the deceased Hitsuji. Seeing this, Ushii finally felt relieved because no matter how bad the other participants were, it could not be worse than Rabbit. Then he sincerely accepted Rat as the winner while vaguely remembering the mysterious warrior's alternative routes he had experienced before.

Juni Taisen vs Juuni Taisen Novel

Ox was doubtful in regards to this Zodiac War due to it having a sudden change of rules on the day, and the reward (granting the wishes of every one of the winning team) was inconsequential. Because of that, he was not very aggressive but still cooperated with the team. When he introduced himself and waited for Rat (Which was under possession by Aries) to do the same, he was taken by surprise when Aries attacked him slicing his head off. Later on, Aries used his corpse to kill Usagi.


  • Ushii's name (失井) is made up of the word ushinau (失う) which means "to lose something (tangible or intangible) or someone; to fail." and I (井) which means "well or waterhole"
  • Ushii doesn't know how to cook.
