And I just realised today that Erwin Smith (Shingeki no Kyojin - blonde guy below) is voiced by OnoD. I reckon the producers set OnoD as Erwin and HiroC (Kamiya Hiroshi) as Rivalle on purpose, since in real life OnoD and HiroC are really close buddies, and in the anime Erwin is a close "friend" of Rivalle's.
