Kisshoten

 At this point in time, Kisshoten is a support character

Background
Kisshoten is the Goddess of Otsutsuki (女神大筒木, Megami Ōtsutsuki), and created the clan eons ago within another dimension. She tried to persuade them to destroy other races encountered throughout the universe, but eventually, the clan rebelled against her, causing her to be sealed away within a Otsutsuki princess, which would later be passed down through the generations and eventually, she was forgotten.

Abilities
Being the originator of the Rinnegan, she possessed extreme prowess in its usage. It is known to possess five Rinnegan, one in each eye and three within her heart, making her chakra extremely powerful and potent.

The first young girl she was sealed within was unknown, bt more recently she was sealed inside of Chiyoko Ōtsutsuki, before being passed into her son, Osamu Otsutsuki and sealed within him as a baby.

The Rinnegan appeared within Osamu's eyes due to Kisshoten manifesting her power within him. She was resealed inside him by his mother, Chiyoko Otsutsuki, using the Spears of Power technique, as the goddess was originally passed to him through birth, being dormant inside of her. Kisshoten's Rinnegan possesses a light grey Rinnegan with white ripples around the pupil of the eye, with glowing orbs on the lines of her sclera. With this Otsutsuki Goddess' Dark Heart within, it holds at least three Rinnegan, which are surrounded mb teeth and can be closed like as normal eyes can, though the opponent will never know. When viewed with a Byakugan, it appears as a black heart, its natural color. With the power of Kisshoten, Osamu has a total of five Rinnegan, three of which are always active, making his chakra quite potent.
