In the past, arranged marriages were extremely common among royal families and other families with very high social status. One of the reasons for this was to create a stronger kingdom/alliance. In most cases, the feelings are never mutual among both parties who are to be wed. They only do it for the sole purpose of their respective kingdoms. In some cases, both parties-to-be have never met each other until the wedding day.

To me, just based on Imu’s silhouette, she looked very much like a bride in a wedding dress. With what appeared to be a dress falling behind her as she walked, something that looked like a veil covering her face and a very tall crown. Due to the tall crown and very large throne she sits on, it makes me theorize that what if Imu is actually Joyboy’s bride through an arranged marriage? And since the wedding never took place, she took the throne that would have been hers had she and Joyboy married.

Imu seems to carry the presence of a bride in her wedding dress before the wedding ceremony. She is not seen by a man, not even the Gorosei. They bend the knee and bow their head as they speak to Imu. This could symbolize the Groom and Groomsmen. The only person shown that was able to hold their head up and stand while speaking to Imu was the women who came to inform Imu about the arrival of the Gorosei. This could symbolize the Bridesmaid’s. And Imu seems to only frequent inside the Chamber of Flowers, which could basically be where the Bride would wait until the wedding starts.

A brides wedding dress is symbolic itself as well. The veil represent modesty and obedience and in some cultures, the veil that covers the brides face is used to ward off evil from draining the brides happiness. Also, during times of arranged marriages, the veil was used to hide the identity of the Bride until the very last minute. This made me think that if what I theorize is true, then Imu will reveal her identity once she meets Luffy (Joyboy), then their “wedding” would finally commence.

I believe Joyboy is a Prince of the Ancient Kingdom who was arranged to marry Princess Imu. This arranged marriage was proposed to the Royal Family of the Ancient Kingdom by the Nerona Family (Imu) solely for the benefit of their own kingdom (for selfish reasons, which is how arrange marriages usually go). But after hearing about the arranged marriage, Joyboy created a plan to finally free himself from his Royal Status and to purse his dream of adventure and freedom.

I theorize Joyboy is a Prince who dreams of Adventure and Freedom but due to his Royal status he cannot pursue that dream. He most likely only could stay within the Kingdom territory and only could leave under supervision, meaning he was always being watched. Hearing that he was arranged to marry, he knew that doing so would cause his dreams to fade, since he would be busy caring for the Kingdom.

On the day of the wedding, Joyboy decides to run away, leading him to go on the adventure of his life. This ended up causing a panic within the Ancient Kingdom, which in turn caused 20 Kingdoms to go against them in their weak time. This was lead by the Nerona family, who was insulted by Joyboy for not going through with the wedding.

I believe that Mary Geoise is actually part of the Ancient Kingdom as well, or atleast a piece of it that was taken and moved to the top of the Red Line. The reason why I say this is because of the throne that Imu sits on is HUGE, and if Joyboy is theorized to be some sort of giant, it would make sense that the thrown that Imu sits on belongs to Joyboy and the Ancient Kingdom. She took it out of spite and pettiness because that throne was supposed to belong to her when her and Joyboy was to be married.

Oda has stated that he doesn’t know too much about “Love” which is why he doesn’t show relationships in the show, other than a small few occasions. But what if this is a red herring as well?

What if Oda is saving his “Love” story for the end? Which is Joyboy and Imu? I mean for a man who named the first chapter “Romance” Dawn, he has to have some kind of play up his sleeve that pertains to Love and Romance that will play a BIG part in the story. I believe it’s going to the Joyboy and Imu.
