無限の住人
Voice actress Kana Ueda noted that when first voicing Rin, she had a sense of incompatibility with the character. As a result, while the director expressed a similar opinion, Ueda's experience helped her to further connect with Rin. She further described her character as "kind of like the onee-san (elder sister) character, where she is responsible for guiding Shiro through his adventure". English actress Mela Lee regarded Rin, alongside "Rozen Maiden"s Shinku and "Blade of the Immortal"s Rin Asano, as one of the works where her career improved.
