User blog comment:AYET/Perona's Negative Ghosts vs Shanks' Haki/@comment-4754162-20120205091900

My opinion: 1) No, Busoshoku Haki could not block something which is not solid (e.g. Kizaru's laser, Kuma's Pad Ho), in this case the Negative Hollow is a ghost. I am not 100% sure about this, please correct me if I am wrong 2) Yes, Haki is a sense of self confidence, thus the stronger the self confidence, the higher level of haki (any kind). Negative Hollow causes victim to be negative, hence loses confidence in themself, thus lowering their haki level, not sure if possible to being it down to zero though
