Mitsuyoshi

Jubei is one of the Six Heroes. He is Konoe's husband and Kokonoe's father. He is also the progenitor of the Kaka race.

Information
Jubei is one of the Six Heroes, Ragna the Bloodedge's master, and Kokonoe's father. He battled the Black Beast alongside Hakumen, and played a part in the Ikaruga Civil War. The Kaka Clan were genetically engineered from his DNA. Despite his physical appearance, he is a powerful warrior, with numerous characters referring to him as the strongest being on the planet. He works to safeguard his friends in their times of need. Before the start of the series, his partner Konoe was murdered by Yūki Terumi. Jubei has a relatively awkward relationship with his daughter, the reason being that he left her in the care of the Novus Orbis Librarium for a large portion of her childhood, while never visiting. After the emergence of the Black Beast in Japan, Jubei was left as the sole survivor of his clan, with his brother, Tomonori, having been killed by Terumi.

For an unspecified amount of time, Jubei worked for Clavis Alucard, and in BlazBlue: Phase 0, went on to be sent to confirm the death of Shūichirō Ayatsuki; should he have found the man alive, Jubei was to assassinate him. Jubei's workings with Clavis were known among the Ten Saints; Nine going on to call him a Clavis' pet cat when they first met.

Alongside his moniker as the strongest being on the planet, Jubei is sometimes referred to as the Mitsuyoshi. Before Jubei met Bloodedge, he went by the name of Mitsuyoshi, after the death of Bloodedge, who frequently called Mitsuyoshi as Jubei, the Beastkin went on to adopt the name Jubei in memory of Bloodedge's sacrifice.

In BlazBlue: Phase 0, the reason why he wears an eyepatch is explained. He sustained severe injuries around his body including his right eye while trying to protect Bloodedge and Celica from a small remnant of the Black Beast. He replaced his eye with his brothers eye; the Sekigan, and wore an eye-patch over the replacement eye itself.

After the War, Jubei was unfortunately left as one of the few survivors of the Six Heroes, Terumi having killed Nine and Trinity Glassfille and forcing Hakumen to sacrifice himself. He was on the run from the organization for many years afterward, being forced to abandon his daughter Kokonoe. After everything that happened he was determined to seal away the Nox Nyctores as Nine had intended.

While on the run, he freed Ragna, Jin, and Saya from a secret lab and then left in the care of his sister-in-law, Celica. He would return to the church years later and train Ragna.

During Calamity Trigger, he is shown to be wandering around Kagutsuchi, appearing in the story modes of Ragna, Hakumen, Tager, Litchi, and Taokaka, as well as briefly during the true ending.

Shortly before the events of Chronophantasma, Jubei trains Jin to use the Power of Order properly as well as inform him of many topics regarding Ikaruga and the NOL such as the Izayoi. He arrives in Ikaruga after his pupils and reunites with Rachel Alucard, Celica, and the remaining Six Heroes. In order to materialize Terumi's true form Rachel uses the memories embedded in Jubei's right eye, the eye of his brother Tomonori who managed to wound Terumi's truest form. Near the end of Chronophantasma, Jubei fights off-screen with Phantom, who is revealed to be his thought deceased lover, Nine. As Phantom returned to Izanami afterwards, Jubei's fate is currently unknown.

Appearance
Jubei is a two tailed black and white cat who stands upright like a human being. He wears a jacket similar to the Kaka clan's jacket, but with an Eastern motif and a cut in the back where his two tails poke out. He also wears an eyepatch on his right eye, although it is hardly seen due to the game's affinity to flip and reuse the same sprite. His weapon, the Musashi, is carried on his back via a belt strap.

When he was young, he wore a Kaka ninja-like orange-yellow garment.

During the Dark War, he wore samurai-like armor.

Powers and Abilities
Jubei's powers, or at least the extent of them, have never been shown within the series thus far. However, being one of the Six Heroes, he is likely exceptionally powerful. Claimed by several, amongst them Hakumen and Terumi, to be the strongest creature alive, it is implied that Jubei is nigh-undefeatable in combat as none have dared to engage in battle against him. His training of Ragna seems to attest to a great power. He wields the Nox Nyctores, the Mucro Somnio: Musashi. With it, he seemed to be able to cleave the shell of darkness that Phantom had surrounded Lambda with during her fight with Nu. Nothing more is known about it. As Jubei's mental faculties do not appear at all to be affected by the weapon in any way, it can be assumed that his mind is very resilient.

Underneath his eyepatch is the eye of his deceased brother, which contains an ability called Sekkigan. It's only known ability is that it forces Terumi's true form to materialize, having done so on two occasions: once when Terumi tried to throw him and Hakumen into the Boundary and again during Chronopantasma as part of a plan to destroy Terumi once and for all.

Personality
Jubei is generally agreeable, sociable and optimistic. Whenever there is a great threat such as Ragna or the NOL around, he always keeps his laid-back attitude and stays relaxed. He makes the best of every situation and is always trying to see the good in everything.

At times though Jubei shows a far more jaded and bitter side. Due to many of his friends having died, Jubei shows deep-seated guilt over his inability to do anything. As such, he has felt  that he's nothing more than a weak coward who runs home with his tail between his legs while leaving good people such as Hakumen and Bloodedge to their fate. The death of his lover, Nine, and having to leave their daughter Kokonoe without a family only further wounds him. Because of those losses, however, Jubei is even more driven to do what's right and will use the power he has to do so.

Trivia

 * Jubei appears to be a bakeneko (specifically a nekomata), a mythical two-tailed cat said to be created when a normal cat grows to a certain age or size. In traditional myths, bakenekos would eat snakes, perhaps a reference to Hazama's hatred of cats (aside from his allergies).
 * Due the fact that he is wearing a tsuba for an eye-patch and wielding two kodachi, he appears to be named after Yagyū Jūbei Mitsuyoshi, a historical Samurai known for having founded the highly aggressive "Yagyū Shinkage Ryū" school of swordsmanship, and for wearing a tsuba for an eye-patch.
 * Jubei's eyepatch is rarely seen in-game due to the game's affinity to reuse and flip sprites.
 * Jubei is actually the one to finish the enemy (or perhaps rescue the enemy from Taokaka's fatal blow) in Taokaka's Astral Heat.
 * As it is hinted in Noel's story in Continuum Shift, Jubei cooks food that comes from a five-star restaurant, hinting that Ragna picked up cooking skills from Jubei during his training as stated in the Material Collection.
 * While Jubei is able to resist any mental affects from his Nox Nyctores, Musashi, it is shown in Hazama's gag reel that he cannot resist any of his cat-like urges when it comes to catnip.
 * In Hakumen's history, it is revealed that the person who Bloodedge gave his life to protect is actually Jubei.
 * Jubei had actually known Ragna, Jin, and Saya when they were still very young, having rescued them from an unknown facility and left them in Celica's care.
 * In Chronophantasma's Tutorial Mode, Jubei will guide the player through the section Stylish Lesson - Application.
