Yoko Taro said the Director’s job is not to design for “fun”, but for the meaning of buying!

I love how everyone in Nier's village cares so much about Nier and Yonah, they treat the siblings like their own family. Maybe it's because he's so kind to everyone and helps them when they need it, even if it means inviting trouble for himself. He did the same for Kaine too
