News that I forgot to put up because I'm an idiot!*
Ladies and Gentlemen, we have an OP! I repeat, we have an OP!
OP's title is called "Stand Proud" (Ha.) It is performed by Jin Hashimoto, known for the opening themes to Kamen Rider Kuuga and Megaman NT Warrior. The full version is expected to be released on April 23rd. It's still unknown if the ED theme will remain as Roundabout by Yes. The composer for the entire series is Yuugo Kanno, whose work include Birdy: The Mighty Decode, Library War, and more recently Psycho-Pass.
