Keiichi (圭一, keiichi), is a minor character seen in the both the manga and the anime adaption. He is the owner of "Milord (ウェサマ)", and the one who prays for Yato to bring it safely home.
As he is still a child, he is quite small. He has brown eyes and his hair is colored brown in the anime.
Not much is known about Keiichi as he is only briefly seen. He is affectionate towards cats, in particular his own. He becomes very upset when his cat, Milord goes missing. He is very polite and well mannered around his mum and he is trusted enough to answer the door unsupervised.
