Bones held an executioner's sword that can erase even 相手 from existence, yet what's truly terrifying about him was his nunchucks.... These.... "love sticks", as he calls them, burn in karmic energy, infusing immense pain & forcing anyone caught under it to undergo repentant enlightenment w/o their consent, often times going insane. So ultimately, perhaps it's best that 相手 avoids Bones entirely.
