(Crossover: DC and Marvel) Love Is a Ray of Light

This was her final mission. Once she completed it, she could retire. Anna thought happily.

Before she left, her superior reminded her again and again that this fusion world was extremely advanced. She had to guide it carefully and facilitate its fusion and advancement.

Although the risks were high, the rewards were considerable. If this world hadn't been connected to the worlds where she had carried out previous missions, she might not have gotten this assignment.

...Wait?! What the heck is going on? Anna was shocked.

Batman's cape from Gotham was offered to her.

Iron Man from New York opened his faceplate. "Hey, sweetheart! I found you."

The Man of Steel from Metropolis descended from the sky and held out his hand.

Anna was surrounded. She was completely panicking. Hey, guys, I don't know you!

Tinkerbell invited you to join "Aquaman's Fish Pond."

Ding! You have joined the group chat "Aquaman's Fish Pond."

Ding! "The Dark One with Green Light over His Head" has joined the group chat.

Ding! "The Red-and-Gold Can with Green Light over His Head" has joined the group chat.

Ding! "The Big Blue Guy with Green Light over His Head" has joined the group chat.

Ding! "The Green Ring with Green Light over His Head" has joined the group chat.

...Ding! Tinkerbell has renamed the group chat "Anna's Ex-Boyfriend Supergroup."

The superhero ex-boyfriends who'd been tricked into joining by the group name: ?

P.S. The heroine's memories are erased after she completes a mission, so at first she doesn't remember her ex-boyfriends. Feel-good story, with a love rivalry. The male lead hasn't been decided yet; I'll pick someone from the supporting cast in the end. The timeline is nonexistent, I guess the heroine ate it. Includes corruption plotlines. Warning: superhero love-rivalry scenes may be out of character. I'll add more if I think of anything else.

Theme: Bring on the love rivalry!
