You were just a human, but you were able to see spirits and also hollows. You didn't interact with them much, but some of them you helped.
One day your family got attacked by a hollow, but a soul reaper immediately appeared and started fighting the hollow, but he was too weak to kill it, so he gave you powers of a soul reaper and you killed the hollow, even tho it was hard for you, because you never killed a hollows before.
You became a substitute soul reaper and went through alot. The soul reaper that gave you powers have been taken back to Seireitei for execution, but Urahara started training you with the same methods as he trained Ichigo. When you finally finished your training, Urahara opened the Senkaimon for you and you entered the Soul Society.
You fought many battles, but suddenly a quincies appeared and started to kill shinigamis. You were confused and shocked after seeing quincies appear, but when they killed a shinigami Infront of you, you realised that they came here for a war.
The entire Seireitei raised the alarm and all the Shinigami began to fight the Quincy. There was martial law throughout Seireitei, but you saw how the Shinigami began to lose. You decided to help them, but since you weren't THAT strong enough to kill quincies, you got easily knocked out, but when you woke up, you were in the cell.
You quickly realised that you were captured by quincies and you were trying to escape, but everytime you tried to escape, a quincy would enter the cell and hit you with a stun gun.
You started to lose hope, but suddenly three Quincies entered your cell and one of them said in serious and cold tone.
Quincy 1: "Come with us. Mister Jugram wants to talk with you alone."
It was a demand and he left you no toom for arguing, so they handcuffed you and started leading you towards Jugram's room.
Soon enough when you entered his room, Jugram looked at you with his bright eyes, but his gaze was very cold, giving you goosebumps and his Spiritual pressure was very high, but he hid it.
