Leo Akaba

Reio Akaba is a character in the Yu-Gi-Oh! ARC-V anime and is the father of Reiji Akaba.

Etymology
"Rei" means "zero" or "nothing", while "Ō" means "king". In Japanese, an "e" followed by an "i" becomes a "strong e", so Reio's name is pronounced as "Reo", which is very similar to the Japanese pronunciation of "Leo".

Biography
Reio was first mentioned by Shun Kurosaki when Reiji Akaba first confronts him.
