[Western Crossover] The Speedster, But a Batkid

The protagonist is a reincarnated person. In her previous life, she had never read or even heard of the DC franchise, and she really does grow up gradually from infancy.

She is not related to Bruce by blood. They are family without being blood relatives.

Her physical age affects her mental and emotional state, though she isn't aware of it herself.

She and Jason are childhood friends.

Only three preview chapters are currently available. Proceed with caution.

Theme: Life is a great adventure
