Yuta Okkotsu is one of the main characters in manga and anime Jujutsu Kaisen. He is a first-year student at Tokyo Metropolitan Curse Technical College and has the ability to manipulate cursed energy.

Yuta's past is a tragic one. He was born with a powerful cursed energy that caused him to unintentionally harm those around him, including his parents and classmates. As a result, he was ostracized and bullied by others, which led him to develop social anxiety and depression. Eventually, he was taken in by Satoru Gojo, a powerful jujutsu sorcerer, who helped him control his cursed energy and enroll in jujutsu school.

In terms of his ability to use katanas, Yuta is proficient in swordsmanship and often wields a katana, in battle. It's unclear how he acquired this skill, but it's possible that he received training in swordsmanship as part of his jujutsu education. Yuta's use of the sword is enhanced by his cursed energy manipulation, which allows him to channel his power through the blade and deal devastating attacks to his opponents.

Overall, Yuta Okkotsu is a complex character with a tragic past and powerful abilities. His proficiency in swordsmanship adds to his already impressive arsenal of skills as a jujutsu sorcerer."
