The anime was later licensed for American distribution by Funimation Entertainment under the title "Rumbling Hearts: Kiminozo". It was originally released in three DVD volumes between December 2006 and March 2007, and was later re-released in a box set in August 2007. The writers for the English dub of the anime in the North American release received a mixed reception for taking a liberal approach while producing the script. This resulted in an interpretive script, which at several points reworks the dialogue. By contrast, the writers for the subtitle script in the North American release produced a script which is more faithful in its translation, going as far as including honorifics. In addition to the differences in dialogue, there is also a marked difference in the displayed level of affect between the Japanese and English voicework, though both were generally well received. For the most part, Takayuki's Japanese voice actor portrays him as severely emotionally numbed (dissociated), consistent with PTSD (one of the major themes). The English voice actor does not perform the role this way.
