How about adding a conjecture (even in trivia) that it's weakness is senjutsu. Yata mirror has the same defensive specifications like TSB aside from being able to turn flesh into ash upon contact. It also has similar ethereal form. So it is essentially artificial TSB. It's common practice to try and replicate powerful techniques and weapons.Rizgubi (talk) 12:17, July 2, 2017 (UTC)
