I ended up asking my Japanese teachers to help me with the name, and I kept some of >>12 and discarded >>3. 蟎 (Dani) is 'bedbug' as my teacher told me, and 獲(Eru) is in fact (E) with okurigana of 'ru'. Most people can't read these characters anyways, so the point's defeated.

My first name is 伝仁江留 (Den ni e ru). I like the softer sound of 'den' over 'da' or 'dan', and the second character is one of my favorites.
