Kajiura: It’s really important for opening themes to garner a sense of excitement in the audience. On that front, I feel that ‘The Other Side of the Wall’ is ideal, both in terms of the sound and the tune. After all, no matter how realistic the story they tell, anime worlds are, fundamentally, not real. As something that serves as the door into those unreal worlds, opening songs have to generate a thrill that makes you forget reality. In contrast, the ending serves as an outro, one that gives you an aftertaste of the show and then returns you to reality. When I write songs that are meant to serve as openings or endings, I’m quite conscious of having them fulfil those two roles.
