I knew Niwatazumi had nui-nui as a sadist, however I was not expecting this. Curious to see if this situation is expounded upon, even in the slightest.
No Shiranui! You'll turn into an Abyssal if you do things like this! 0__0
if i understood correctly one of Niwatazumi comments, it seems this was a request by someone, but it made him feel bad afterwards, so he is not doing things like that again.
