I was not actually aware that Hollowknight was about buggies.
Edit: Stream video and audio seems a bit desynched.
"Zanpakuto" i a term mad up for Bleach, referring to one of several things that amounts to "magic sword with powers activated by calling its names."
A big-ass anime sword is a zanbato, though that term only exists in anime and related media. Outside of replicas, they are not real.
Edit 2: The video-audio desynch might have been a problem on my end rather than the video itself. Early in it like, skipped a minute of video while the audio carried on as normal, but after a while the video reloaded and the footage backed up to match the sound.
Might just be the video lading weird when I try and watch it.
