It can also appear as clothes or hide underground :D Yeah, maybe But Naruto's emotion sensing which he gained thanks to kurama (whom i assume gained it from maybe the six paths or this ability might be unique to him) can sense emotions, not chakra

Even kisame couldn't stay hidden inside samehada since naruto discovered him using this ability even though kisame's chakra was overshadowed by the blade's own chakra

BZ's chakra (or his emotion) should have been sensed by the sage/kurama
