All of this "Masaharu Arisawa" artist tag is supposed do be called "Celluloid Brothers" (セルロイドブラザーズ). I searched in net, and I haven't found anything about person Masaharu Arisawa. I though it might be his reak name, or other pseudo. I could change the tag, but i don't know how to change all in one shot, and I don't feel enthusiastic about changing them one by one.
