Chapter 159- Transformation (Part 2)

For Rin, it means that he becomes closer to the peak of power in this world than ever before. It meant that he finally broke down the limit that was put on him for being a human and turned into another completely different being that possessed the strength to manipulate and twist reality itself.
That's what being the strongest means. To finally be able to not fear anything that can stand in front of you.
