I was replaying the game and searched Castelia City on the site out of curiosity; hence, finding the theme by DSOD.

I was going for "Mewmore x Dagust // Summer in Lacunosa" for the BGM but I preferred Clock Tower in the end (Quality is higher and easier to loop too).
Loop was all possible due to Kame Editor.
