Note from Author:

As explained in summary Hikari himself is not reincarnated individual but he know about Jujutsu Kaisen world from his Grandfather who also teach him sorcery. As a child he thought his grandfather story he read are just nonsense that his grandfather made up using Jujutsu society as setting. Even when his grandfather make him do Binding Vow he just thought of it as his grandfather being embarassed by his own story.

However meeting Gojo, Yuta, Geto, and Fushiguro convinced him that it was reality. He was forced to accept this and entering the school to improve his skills, and if possible change the terrible future.

Also the reason he doesn't know about Gojo is overall similar to Kugisaki he don't know anyone who are willing to share information about Jujutsu society with him. He has no proper reltionship with any sorcerer, and his job basically just come from agent of Jujutsu Society via phone. He manage to get promoted despite that mainly due to his curse technique being so unique the higher up wanted him so badly.
