I love love mitsuhashi wataru, koitsuda renya, ichijou hirame and so many other seiyuus mentioned by others as well. I think I was first exposed to mitsuhashi wataru as well, and was so surprised to see his name everywhere but I totally get it now
Recently have been really into uitoki cherry as well!
Now that I've consumed all there is to consume with Sen Yagami and Mitsuhashi Wataru's works, I'm currently obsessed with Rei Hashiba. I find his voice and acting on the level of those two heavy hitters.
