There are four Oni Clans; The Red Oni Clan, the Blue Oni Clan, the Green Oni Clan, and the Yellow Oni Clan. Though, there are five types of Oninoko; Red, Blue, Green, Yellow and Black. The Black Oninoko is a special variety, and can only be found in the Dreadlands. Similar to the Oninoko, there is also a "race" called the Ogrima, though "mutation" is more fitting than race. Ogrima were Oninoko that were chosen by the Shogun to be "awakened", and are now stronger in every aspect, whether physical or mental.

The Oninoko are the dominant race in the Oni Clans, with some Oni who are Shoguns of specific regions. Oninoko have characteristics dependant on which Oni Clan they originate from, as those characteristics are decided by what type of Oninoko their parents are. In the case that an Oni and an Oninoko breed, an Oninoko is born with the Oni's clan color (if the Oni was a green oni and the Oninoko was a red Oninoko, the child is a green Oninoko). In the extremely rare case that an Oninoko is born from parents of two different clans, the resulting child is an Oninoko with either of the parents clan color.

The Oninoko make up the working class of an Oni Clan, and in every town/province there is a daimyo (equivalent to a lord) that controls that area. A daimyo is almost always an Ogrima, as everyone granted the privilege of becoming a daimyo is also given the choice of becoming awakened. Most importantly, each Oni Clan has a Shogun, an Oni of the clans color. These Oni have ultimate control over the clan.

Oninoko Traits

As an oninoko, you have the following racial traits.

• Ability Score Increase. When determining your character’s ability scores, your Strength score increases by 2 and you increase a different score by 1. You can't raise any of your scores above 20.
  

• Age. Oninoko reach maturity at the same rate as humans, but live till about 175.

• Speed. Your base walking speed is 30 feet.

• Darkvision. Thanks to your oni heritage, you have superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

• Oni Bloodline. You know the primal savagery cantrip. Charisma is your spellcasting ability for this cantrip.

• Powerful Build. You count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.

• Shapechanger. As an action, you can magically polymorph into a Small or Medium humanoid. You determine the specifics of the changes, including your coloration, hair length, and sex. You can also adjust your height and weight, as long as it matches the creature size you polymorphed into. You can make yourself appear as a member of another race, though none of your game statistics change. You can't duplicate the appearance of a creature you've never seen, and you must adopt a form that has the same basic arrangement of limbs that you have. You stay in the new form until you use an action to revert to your true form or until you die.

You can use this feature once a day, recharging after a long rest.

• Languages. You can speak, read, and write Common and Oni (Giant script).
