The mysterious “D” initial in One Piece has intrigued fans since the beginning of the series. Characters like Monkey D. Luffy and others bearing the “D” in their names have played significant roles, making its meaning one of the biggest mysteries in the story. While only the Roger Pirates know the true meaning, Eiichiro Oda has left several hints throughout the series.
Recent developments in the Elbaf Arc, particularly in One Piece Chapter 1138, have provided new insights into the origins of the D Clan. By connecting these hints with past lore, a compelling theory emerges: the D people are linked to the ancient Moon civilization and may be descendants of both Moon-dwellers and Earthlings.
The Full-Moon People and The Sky Races from Birka
Their Existence on the Moon
To understand the D Clan, we must first examine the origins of the Full-Moon people, also known as the Sky Races. The One Piece world refers to Earth as the “Blue Star,” but the Moon plays an equally significant role. The Sky Races—Shandorians, Birkans, and Skypieans—originated from the Moon, where they built the ancient city of Birka and created the automata. Some theories also suggest that the Lunarians lived there.
The Settlement on Earth: The Blue Star
As resources on the Moon dwindled, the Sky Races migrated to Earth. Each group settled in different locations:
- The Skypieans established Skypiea.
- The Birkans created another Birka on a Sky Island northwest of Skypiea.
- The Lunarians built the City of Gods atop the Red Line.
- The Shandorians settled and made Jaya on the Blue Sea their home.
Despite their separation, these races likely retained their advanced technology, which played a crucial role in shaping Earth’s history. However, Birka was destroyed by Enel eight years before the current timeline after he consumed the Goro Goro no Mi.
This advanced civilization from the Moon holds the key to understanding the D people.
The Half-Moon People and the Kingdom of the D Clan
The People of D Stem from the Half-Moon People
The full truth about the D Clan remains unknown, but clues from the series hint at their origins. The Harley inscriptions revealed in One Piece Chapter 1138 mention the “Three Worlds,” each describing a different era:
- First World – Humanity defied the gods, leading to destruction and separation.
- Second World – The Half-Moon and Full-Moon people coexisted, but war erupted, resulting in another great divide.
- Third World – A fractured moon and a new dawn, possibly foreshadowing the D Clan’s return.
The “Half-Moon” concept is crucial—visually, a half-moon resembles the letter “D.” This suggests that the D people are descendants of interbreeding between Moon-dwellers and Earthlings, possibly seen as outcasts at the time.
Luffy and the D Clan’s Alien Connection
If the Shandorians were the first Sky Race to settle on the Blue Sea, then those with “D” in their name—including Luffy—may have Shandorian ancestry. This means that all members of the D Clan are, in a way, part alien.
The Technological Prowess of the D Clan
The Ancient Kingdom and the Mother Flame
The Full-Moon people possessed immense technological knowledge, as seen in the ancient city of Birka. Their descendants, the D Clan, inherited this knowledge, which contributed to the rise of the Ancient Kingdom—an advanced civilization that once thrived before the Void Century.
One key piece of this technology is the Mother Flame, an undying power source similar to the Sun. Vegapunk hinted that such a power source existed in the past, possibly created by the D people and the Sky Races. However, this knowledge made them a target, leading to the Great War against the 20 Kingdoms and the eventual erasure of their history.
Conclusion
Oda continues to drop hints about the D Clan, suggesting that they are deeply tied to the Moon, ancient civilizations, and the lost history of the world. If the Half-Moon people truly represent the D Clan, then Luffy and others like him may be destined to bring about the long-awaited “Dawn” of the world.
With One Piece Chapter 1139 set to release on February 9, 2025, fans can expect even more revelations in this thrilling saga.
