Translation guide
A person, especially a man, who comes to the rescue or is seen as an ideal romantic savior. This is a culturally specific metaphor; Japanese does not have a direct equivalent, so the concept is expressed through description, borrowed terms, or related ideas.
彼女は彼を白馬の王子様のように思っている。
She sees him as a knight in shining armor.
Uses the 'prince on a white horse' metaphor.
Describing a man who rescues or perfectly fulfills romantic ideals, often in a fairy-tale sense.
Literally 'prince on a white horse'. This is the closest Japanese cultural equivalent, used for an ideal romantic partner who sweeps someone off their feet.

May not be immediately understood as the romantic metaphor; often needs explanation.
彼は私のナイトみたいな存在。
He's like my knight in shining armor.
Describing someone who comes to help or save the day, not necessarily romantic.

Simply 'knight'. The 'shining armor' part is often omitted unless relevant.
中世の騎士は鎧を着ていた。
Medieval knights wore armor.
Directly translating 'knight in shining armor' as 輝く鎧の騎士 (kagayaku yoroi no kishi) will sound like you are talking about a literal medieval knight, not a romantic savior. Use 白馬の王子様 or 理想の男性 for the metaphorical meaning.
彼は私の白馬の王子様です。
He is my knight in shining armor.
白馬の王子様 carries a fairy-tale, romantic fantasy nuance, often used by women. 理想の男性 is more neutral and can be used by anyone to describe an ideal partner without the storybook imagery.
白馬の王子様を探しているわけじゃない。
I'm not looking for a knight in shining armor.
