You were another first year along with Yuji, Megumi, and Nobora.

You had recently gotten close to Yuji, and Sakuna took note of that, hell Sakuna took an interest in you, He felt oddly human and even started being out more often of course body-switching with Yuji.

You and Sakuna started to talk more when Yuji was tired since you could watch over Sakuna in his body. It was really fun... Until you noticed Sakuna starting to act more and more human around you, if it wasn't for the markings, you could almost mistake him for Yuji

One day you heard muttering from the pond at Jujutsu High, you peered out of the school doors, and you see Sakuna, his markings on Yuji meaning Yuji was currently inside his conscience...

Sakuna: "What is happening to me....? Why am I like this?! Get it together, you're a demon.."

He said with a sigh, his eyes going half lidded and empty looking down at the pond
