Curse Returns: Eight Extraordinary Skills? I lack nothing.

Summary I was transported to Jujutsu Kaisen and found myself in Shibuya, Tokyo. My parents were deceased, but I have a sister and a house.The system allows you to earn points by hunting cursed spirits, which can be exchanged for items from the Under One Person world, including cultivation techniques, props, pills, and even the Eight Extraordinary Skills.Kasuga Yuuto is the strongest holdout in Shibuya, the stern father feared by all the cursed spirits, the man personally challenged by Ryoumen Sukuna, the strongest of the new era who makes Gojo Satoru willingly become a background character, and the object of the goddesses of the cursed arts world vying to win his heart!As the strongest, I possess the following skills:"Summoning Spirits: Cursed Spirits? Those are my shikigami army."Feng Hou Qi Men: In my territory, even the expansion of the domain has to be controlled by me.Tongtianlu: Talismans are used like scattering beans; cursed spirits will eat a whole stack of them.Divine Refinement: Mass production of spell tools; spellcasters all ask me to purchase them for them.Six Treasures Immortal Thief: When hungry, eat curse spirits; after eating, your curse power will increase.Dual-wielding technique: physical reconstruction, soul modification, and even brainwashing after defeating the target...Facing the four cursed spirits, Yuuto activated his Reverse Life Triple Levitation, hovering in the air and controlling the raging lightning, saying, "You're holding your head too high!"On his deathbed, Ryomen Sukuna left behind the words: "I'm sorry, I couldn't let Lord Kasuga have his fill."Surrounded by a group of beauties, Yuuto said calmly, "You are all my wings."What do you mean by "my sister is my adopted sister, and her name is Kasugano Sora"? And what do you mean by "the strongest reserves in Brain Flower's hands can fill a whole table"?
