Yes! If I know right, #4 have a "death" connotation in japanese, so even building may not have level 4, just like we can avoid #13 in westerns countries.
Neat! And, yeah, that would make sense. I've entered some buildings without floor #13. XD
Don't underestimate the Aces! They wear number #4 for a reason! ლ(´ڡ`ლ)
