Mitsuyoshi

Jubei is one of the Six Heroes, and Kokonoe's father.

Information
Jubei is one of the Six Heroes, Ragna'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 appearance (he is considerably short and does not come off as threatening, resembling a cat more than either of his descendants), he is a powerful warrior, with numerous characters referring to him as the most powerful being on the planet. He works to safeguard his friends in their times of need. Before the start of the series, his partner Nine was murdered by Terumi Yuuki. Jubei seems to have an awkward relationship with his daughter, though why is currently unknown.

During BlazBlue: Calamity Trigger, he is shown to be wondering around Kagutsuchi, appearing in Ragna, Hakumen, Tager and Taokaka's story modes, as well as briefly during the true ending.

Appearance
Jubei is a short, Nekomata, cat-like beast-man who wears a jacket similar to the Kaka clan's jacket. His swords are attached by a strap and rest behind him, and the lower back of his jacket has a cut in the centre, with his two tails poking out.

Powers and abilities
Jubei's powers or the extent of them have never been shown within the series but his status as one of the Six Heroes makes him exceptionally powerful. Claimed by several, amongst them being Hakumen, as 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 to Ragna seems to attest to a great power. He wields the Nox Nyctores, Musashi. As Jubei does not appear at all to be effected by the weapon in any way, it is indicated that his mind is very resilient.

Trivia

 * Jubei is actually the one to finish the enemy in Taokaka's Astral Heat.
