The title of this chapter is “カルディア(心臓)”, the first part being the name Cardia in kana and the second part is the kanji for heart. At first I thought this meant something like the heart, or spirit of Cardia, but it didn’t make sense, so I mistranslated it as “Dedication to Cardia”. What I didn’t know, is that the Greek word for heart, καρδιά, is also Kardia. So the chapter title is actually just the word heart! But to keep the original title in mind, I renamed it to “Cardia (Heart)”.
Thanks to Cloud for figuring this out with me!
