In case specific Arte Refact members aren't listed in the anime or the soundtracks,
their works page doesn't list specifics but the post is linked on the profiles of Tsukasa Yatoki, Atsushi Harada, Kyohei Yamamoto, Masatomi Waki, and Tsukasa Kikuchi. SHINTA-LOW doesn't have a page and could theoretically have worked on it too (though he hasn't tweeted about it).
