Sae states he much rather die or play in Europe with a bunch of college students than play in the J-League or play on the Japan National Team. Sae has a lot of pride as a football player, looking down on Japanese football and all who participate in it. He is egotistical in his football play but has shown to be able to restrain himself and play his position, not trying to outshine others unnecessarily. Sae can also be arrogant and condescending looking down on others even if they are older than him and have more organizational authority.
He has only ever cared about becoming the best striker in the world and has only had time for things that get him closer to his goal.
Since a young age, Sae has been cold, blunt, and very serious.
