I'm a Celestial Dragon Today. Seriously?

Euphemia, a knight of honor. She was born in Mary Geoise.

She was once the younger sister of the red dragon who ruled Britannia and the Witch of the Island, as well as a member of the Knights of the Round Table. When she opened her eyes again, she had become the youngest daughter of the Figarland family, a Celestial Dragon among Celestial Dragons.

What lies beyond Mary Geoise? The freedom she yearns for.

So she set sail, promising that she would join the God's Knights after she returned. But before that, she became a CP0 agent, a Marine, and a rising pirate.

Marine Headquarters:

"I feel like you remind me of that famous pirate from a few years ago. Is it just my imagination?"

"Ha ha ha, sir, what are you talking about? I'm a Marine through and through. How could I have anything to do with pirates?"

"Fleet Admiral, I hereby resign!"

"Why? You're a promising young vice admiral. You have a bright future in the Marines."

"Because my family is pressuring me to come home and take over the family business..."

At nine, she ran away from home for the first time and matter-of-factly told the CP0 agents assigned to watch her that she wanted to join.

At twelve, she knocked the sword out of her brother's hand, put on men's clothes, and set sail to see the world.

At seventeen, she became a Marine, a promising young vice admiral with everyone's hopes riding on her.

At twenty-four, she resigned and decided to return to her old profession as a knight.

At thirty, she took part in the Paramount War, using her status as a Celestial Dragon to threaten the Marines.

Brilliant flames flickered in her eyes.

She performed the sword-drawing move she had practiced thousands of times, etched into her very bones.

"Divine... Departure!"

As she unleashed a technique belonging to one of the Four Emperors, her overwhelming Conqueror's Haki swept across the entire battlefield like a tidal wave!

She leaped onto the bow of the Red Force, which had just arrived, and stood beside Red-Haired Shanks.

She laughed boldly and freely, waved toward Marineford, and shouted:

"Mr. Sengoku! Tell my family for me! I've defected!"

*The protagonist is an expert at maintaining secret identities. The plot is all about having fun, and the protagonist may be a little overpowered. She's a growing protagonist.

*There will be cross-dressing and plenty of secret identities getting exposed. The author loves that kind of reveal.

*The blurb may change, but the core premise won't.

*There may or may not be a romantic pairing. The author struggles with romance plots.

*She's Shamrock and Shanks's younger sister, but the other Celestial Dragons won't get much page time. No Red storyline, though there may be extra chapters.

*The Type-Moon history is just background. Related details will be explained if they become relevant, so readers who don't know it can still follow along.

*Since she's a Celestial Dragon, the early plot may mention slavery. If that bothers you, please stop reading.

*Updates when possible. The author is busy in real life, so chapters will be posted as they're written. This will not be abandoned.

Theme: Euphemia, you are free.
