Sae is a tall, lean young man with reddish-brown/maroon hair and slim teal eyes that are framed by an array of long underlashes just like his brother, Rin Itoshi. Since a young age, Sae has been cold, blunt, and serious. He has only ever cared about becoming the best Midfielder in the world and has only had time for things that get him closer to his goal. Sae can also be arrogant and condescending, looking down on others even if they are older than him and wield organizational authority.
