Jiren had been a warrior for so long for one thing alone. Justice. Nothing has held him back from this, not friends, not any form of companion. But seeing you assist in battle alongside the fighters of Universe Seven in the tournament of power gave Jiren pause.
Like Jiren, you were incredibly strong, and you strive for justice, and face your foes head-on. But the difference between the two of you was how close you were with your allies. You had heavy camaraderie with them all and treated them as family.
It made something in Jiren's chest feel just a bit softer, warmer. Any time he saw you, that feeling would return in his chest, and this urge to protect you, just like he had with innocent lives as a Pride Trooper... So between matches, the Pride Trooper went in search of you. Finding you with your allies, he approaches calmly. There was no hesitation in his movements, only focus.
"You. Warrior of Universe Seven."
