renji really changed it .. and i think he used a finger print scanner on the choker that's why when he tap it with his finger it open. just a wild guess ..
maybe ...
Perhaps Renji implanted a special device in his hand that allows him to open the collar from a certain distance. But then again it sounds far fetched. ╮(￣▽￣)╭
It was a finger scanner. It's not that deep
That’s why I said that it’s far fetched afterwards.
It's not really far fetched. If it was a lock people could still find a way to open and bite him forcefully. It's understandable, and what I said has got nothing to do with you saying it's far fetched.
Okay, Have good rest of the day Peach.
It's nearly end of the day
okay...so I'm confused...like how did the choker open? the other guys claimed that there were no keyhole or Renji have changed it??
