Akira is very close with Yorihisa Haninozuka, the father of Mitsukuni Haninozuka aka Honey and Yasuchika Haninozuka aka Chika. They are the same age, similar to other "pairs" of Morinozuka and Haninozuka men. It's implied that their relationship is similar to their sons, as he says it is in his family's blood to be loyal to the Haninozuka family. He and Yorihisa often settle their own arguments with food. He loves his sons and nephews, but he thinks Honey's antics get Mori into a lot of unnecessary trouble.
