Rain (translation of 雨) is incredibly skilled at bringing drama and emotion to their scenes. On one hand, they are able to take a bustling environment and put you in it — surrounded by the crowd, noises and excitement of the moment. On the other hand, they are particularly masterful at capturing the intensity of silence.
There is something deeply psychological about the way Rain is able to handle the interaction between the characters and the integration of their emotions with the setting. The emotion radiates well beyond the characters and throughout the entire scene, tying each piece together in a potent package of a single feeling.
