Oni are a race of malevolent spirits given physical form. Most oni begin their existence as kami, spirits tasked with the protection of a specific part of the natural world, but for some reason reject their duties and turn to evil. Less often, the souls of particularly vile mortals can become oni upon death. When oni first form, they are intangible, powerless spirits. In places with strong connections to evil, or as a result of unspeakable rituals, these formless spirits can gain physical bodies drawn from a humanoid species, often one predisposed to war— though their spiritual origins also give them the power to shapeshift. There are known to be oni that resemble drow, humans, giants, shirrens, and vesk, but among the most common oni are the ja noi, who have ties to the violent and militarist race of hobgoblins.

Ja noi are distinct from hobgoblins in appearance due to their bright-red color, prominent ridges on their brow and forehead, a near-permanent facial grimace, and even greater size and muscular frames. Ja noi stand over 6 feet tall and weigh roughly 220 pounds. A ja noi is particularly driven to experience the sensations of battle, actively seeking to lead armies and build empires. Ja noi fight in close combat if possible, and while perfectly capable of reveling in victory won with starships and huge fighting machines, they take every opportunity to lead infantry assaults and fight in face-to-face confrontations. Ja noi often gather hobgoblin soldiers to fulfill their need to command troops. For their part, hobgoblins normally embrace the presence of a ja noi within their ranks, seeing them as among the most perfect expressions of the hobgoblin form and treating them as mighty heroes.

Some hobgoblin groups interact so closely with ja noi that children are sometimes born to one ja noi parent and one hobgoblin parent. Known as kanabo, a term that means “the strongest,” these oni-blooded goblinoids breed true with both ja noi and other goblinoids. They have innate powers that often make them champions of their people, though they also often develop an independent streak that causes them to reject hobgoblin rules and society. Kanabo share the size of their oni ancestors, but their appearance is much more variable, ranging from stout hobgoblins to forms closer to half-orcs, and some even appear nearly human. The average kanabo is over 6 feet tall and weighs 250 pounds.

Special Abilities

Dying Vengeance (Ex) When a tsabagu is reduced to 0 Hit Points, it can make a single melee attack as a reaction. If this attack is against the creature that dealt the damage that reduced the oni to 0 Hit Points but misses, the oni still deals an amount of damage equal to the oni’s Strength modifier.
Tsabagu Onslaught (Ex) When a tsabagu makes a full attack, they can make up to three attacks instead of two attacks. The oni takes a –6 penalty to these attacks instead of a –4 penalty.


Tsabagu oni come into being when a malicious spirit successfully incarnates into a shobhad. In their natural form, they’re four-armed humanoids with blue skin and a dramatic brow ridge over their one baleful eye. Their powerful jaws are decorated by a pair of black tusks.

Shobhad culture greatly idolizes strength, and so tsabagus often quickly rise to positions of leadership or great influence. These exalted oni often set about raiding surrounding settlements to recruit more shobhads into their ever-growing fighting forces. The only authority tsabagus are willing to defer to is that of even stronger oni.

While tsabagus with power and influence are undoubtedly terrors on Akiton, those that make it off-world can become threats to entire systems. These tsabagus can end up leading ruthless mercenary companies or space pirate crews. Their lust for violence and domination is never satisfied, and attacks from such gangs rarely leave any survivors.
