s01e21 — Secret Garden

This old man is kind of muddy... And Yukio took his word for it? Maybe he's not their grandfather at all, but just a crazy fanatic. I hope that in fact everything is not as stupid as it seems.

Of course, I fell out when I saw Yuki in the ranks of my grandfather. I understand everything, but I don't understand this. In fact, Grandfather is against demons, which means he won't fight for Rin's life either. Perhaps Yukio should join his grandfather, tk did not know his mother, and grandfather, in fact, is the only source of information about her.
It's all kind of weird...
