There is an episode that when Hideyoshi TOYOTOMI was alive, Okaru who was held hostage in Osaka-jo Castle got out of the castle without other people's support and went back to Ieyasu on horseback, but obviously, this will be a fiction.
また、豊臣秀吉存命中に人質として大坂城に捕らわれたが、単独で脱出し騎馬にて家康の元に帰ったという逸話もあるが、これはさすがに創作であろう。
