Question: why was yato crying in episode 2?
Answer: Noragami: Yato cries over Yukine's tragic past. I love this moment in episode 2 of Noragami because it shows the depths of Yato's compassion and his affinity for Yukine. ... From a distance, Hiyori watches Yato and wonders why he's crying. It's clear that Yato cares for Yukine from the start.
