I've spoken to Lusky again and, basically, it is VERY VERY unlikely to be that. Even if it sounds similar. The kana is wrong and this is also too obscure a reference. Sorry.
Haha, no biggie, I jumped too quickly onto the dance floor
Our guy: キュビルデュヌス
キュ / kiyu --> cue? (long straight wooden rod used in snooker, billiards, etc), fits his nose
ビル --> (e)vil
デュ / deyu --> diu, means "long" in Latin (but in the temporal sense..). "Diu" means also "by day", "diurnal".
ヌス / nusu --> nusu for "nose"?
..long evil cue for a nose
With kana swapping:
cue +
ビルデ --> デビル: that's "devil".
ヌス --> スヌ: that's "snoop"? (google says)
..snoopy cue of the devil
But cue makes sense though
