The Giant And The Mermaid

Risk taker,Diana Morgan (aka.Skipper) is a pro hero based in the USA.She is the No.2 ranked hero in America and has the ability to bend water at her will.
She is adored in the eyes of the public for being rebellious and strong but what most people don't know is when she was in her beginner days,the feisty sea-bearer was 'involved' with the big man himself,All Might while he was in America
But as we all know,Toshinori went back to his home and became the No.1 hero and Diana became successful herself.
But they never forgot about each other and still sent occasional e-mails.
Now,years later,a frail All Might returns to the US accompanied by his students and the two meet again.
What will happen this time,now the heroes are adults?
