Yuji and his introduction to curses or sorcerers and his wild adventures are really the by-products of him not wanting to join sports clubs. Thanks to his immense strength and physical abilities, he managed to catch quite a few of the school clubs' attention.

The track team was especially attracted to Yuji for his speed and relentlessly asked him to join. Yuji, not wanting to join any of the sports clubs, decided to join the Occult Club, simply as a reason for him to say no to these requests. This leads to him finding the cursed object and meeting Megumi, catapulting him into the world of curses.

He was born on March 20th, but his exact age is unknown. He is likely 15 or 16 based on his high school status and demeanor. It doesn't seem like it would be an important detail, but it is these minute details that bring a character to life.He first shows his resistance against poison when fighting Junpei and resisting Moon Dreg's poison. It is possible that, among his other already superhuman abilities, he also possesses a strong natural resistance to poisons and curses. He could also have developed a resistance to poisons after eating Sukuna's finger. Sukuna was known as the King of Poisons as he had absolute mastery over them. So, it is very possible that Yuji, who is capable of housing Sukuna or being his vessel, acquired this resistance through the action of eating the finger.Yuji has always had incredible strength, even before his acquiring of cursed energy. He was nicknamed "The Tiger of West Junior High" for his strength and stamina. His superhuman strength.
