Yuta Okkotsu

Yuta Okkotsu is a 6'3 17 year old lean light-skinned young boy with medium length matte-black hair, deep purple eyes, a long sleeved white shirt-jacket that has dark purple flame designs on the hood, sleeves, and collar, dark black pants with the same purple flame designs as his shirt, and white shoes, along with a silver ring(Rika gave this to him, after making him promise to her that they would get married when they grew up)the same ring that would later be the storing place for Rika's Cursed Spirit body, and a katana that he nicknamed "Purple Haze" with a purple hilt, white tsuba, and a silver blade with purple flames on it

His mother died from an illness when he was 4, and his father abandoned him after his mother died, believing that it was his fault that she died, and he was taken in and raised in an all-female monastery by Utahime Iori(a tall woman with dark purple hair, steel-grey eyes, a light-skinned complexion, and a lithe-athletic physique, she usually wears a white kimono and a red dress), where she taught him everything that he knows as far as Jujutsu Sorcerery, Tactical Knowledge, Intellect, etc., but Yuta had to teach himself hand-to-hand combat and swordsmanship, since Utahime wasn't much of a fighter

Yuta was born with an ability that's called "Copy", which allows to copy the ability of the entity(person, animal, creature, inanimate objects, etc.)but Rika has to eat a body part of the respective entity, and once she does, the ability is stored within her, and her or Yuta can freely draw on and use the techniques at his/her own will, and as for Yuta's Domain Expansion: Authentic Mutual Love(it resembles his mindscape, an all-purple area with purple flames(they represent his mana), an all purple ground with an endless graveyard(that represents the endless amount of people and loved ones that he's watched die in front of him), and inside of every single square inch of the domain is a copy of his sword, and when he picks it up, he can use the cursed technique that's associated with it, and once the technique is used, the sword disappears from his hands, and reappears somewhere else within the domain) and his two Maximum Techniques are: (True Love Beam): he points his katana at his opponent, and Rika shoots a purplish-pink beam of mana out of her mouth at wherever Yuta’s katana points (Jacob's Ladder): a large golden-yellow pillar of light that evaporates all matter from existence comes out of the sky, erasing anything or anyone that it touches

Rika is Yuta’s childhood best friend that was ran over by a car at the age of 10, and in the combined force of Rika's adamant refusal to leave Yuta’s side, and Yuta’s blatant refusal to let Rika die, it created a Binding Curse, the same curse that was responsible for turning Rika into a monstrous curse with an enormous light-grey muscular upper body, long arms, a muscular dark-grey lower body, and a pair of long dark-grey digitigrade(animal like)legs, and Rika has one enormous cycloptic eye that was normally hidden behind a shell that looks similar to a brain, and she has sharp claws on her hands and feet, a mouth full of sharp teeth, and she also stores all of Yuta's copied cursed techniques(about 800 million attack moves in total), Rika also has an endless amount of dark purple cursed energy that Yuta can draw on at his own will, Rika can instantly heal herself or Yuta at her will

Simple Domain: a barrier that protects him from the Sure-Hit Effect of another Domain Expansion Reverse Cursed Technique: instantaneous regeneration via Cursed Energy, can heal lost limbs, wounds of any scale, etc. Falling Blossom Emotion: downscale the damage received from any attack Domain Amplifcation: can directly negate all attacks and damage upon activation Black Flash: a physical attack that is imbued with Cursed Energy within 1/1,000th of a second, amplifying the damage of the attack by 10x
