[It's Kouki's favourite example of his ridiculous life.]

The demon god, Beldr, and his mother dreamt about his death. Because of this, his mother went around and get every object on earth to give their vow to never hurt him. But she never ask the mistletoe, either because it's too unimportant and nonthreatening, or too young to make a vow.

Other than that, Beldr's pretty much invincible to everything.
