>>18179847>Deh-deh-nayWhere did your "nay" pronunciation come from the ネ (ne)? If it was from ネイ (nei) then it'd be understandable but the name doesn't end with a イ (i) nor anything that could give it a "nay" pronunciation.
Also "デデンネ" is "dedenne".
Here's the closest English pronunciation I could probably give:
"de-den-neh"
Pronounce the first "de" as Den without the n.
Pronounce "neh" as Meh but with a n instead of a m.
