Background

Diumil is a Lunarian who was relentlessly hunted by Cipher Pol before fleeing to Sky Island. Annus saved him there, after which Diumil began following him. He became one of Annus's three officers and, aside from Lilith, one of his most trusted confidants. 4

The World Government's persecution had pushed the Lunarians close to extinction. Diumil continued searching for information about surviving members of his people, while Annus promised that any Lunarians found would receive his protection. 4

Appearance

Diumil presents himself as a ghostly, concealed figure whose appearance is shaped by the need to hide his Lunarian identity.

• Thin build.
• Usually wrapped head-to-toe in black bandages, leaving only his eyes visible.
• Broad, pitch-black wings.
• His Lunarian traits include flames behind his head, a feature he and his allies try to keep hidden. 4 42 43
• In Phoenix form, his body is covered in blue and yellow flames; in human-beast form, Phoenix wings overlay his original black wings and his feet become talons. 42 43

Personality

Diumil is calm, disciplined, and unwaveringly obedient to Annus. He remains composed even when facing Shiki's anger and consistently carries out orders without delay. 4 6

He is notably humble about his own value. When Annus offered him the Phoenix Fruit, Diumil initially believed it should go to Lilith rather than himself, seeing himself primarily as Annus's servant. He accepted the fruit only after Annus framed it as a way to better serve the faction. 41

Years of being pursued by the World Government made him highly cautious. At Water 7, he concealed allies in robes, changed routes through the canals repeatedly, and ensured no one was following before bringing them to the hidden shipyard. 37

Abilities & Skills

Lunarian Physiology

Diumil's Lunarian body grants him exceptional toughness and compatibility with extreme conditions.

• Can withstand the recoil of a Reject Dial, a force normally fatal to its user. 6
• Possesses black wings and the ability to produce flames, though revealing these traits risks exposing his race. 42 43
• His exposed heritage made him a World Government target, with a 100 million Berry reporting reward offered for information on a Lunarian's location. 45

Phoenix Fruit

Diumil consumed a Mythical Zoan identified as the Phoenix Fruit.

• Initially increased his physical strength to approximately three times its former level. 42
• Enables full Phoenix and human-beast transformations. 42 43
• Produces blue Regenerative Flames that rapidly restore damaged cells, even after severe damage to bones and vital organs. 43
• His regeneration is limited by stamina; overwhelming damage that exceeds his endurance may still defeat him. 43
• His Phoenix form prioritizes survivability over raw offensive power, requiring Haki, Dials, and his red flames to enhance attacks. 43

Dial Combat

Diumil inherited Annus's Sky Island combat techniques and passed them on to the Angel Legion. 6

• Reject Dial — Defeated the 100-million-berry pirate Sakin with a single strike that launched him through a ship's bulwark and into the sea. 6
• Impact Dial and Slash Dial — Uses both beneath his bandages; in Phoenix human-beast form, he combines them with Armament Haki. 43
• Red flame enhancement — His red flames can empower Dial attacks into fiery impacts and flaming slashes. 43

Haki

• Uses Armament Haki to coat his Phoenix talons and strengthen his Dial attacks. 43
• Was assigned, alongside Yale, to design training programs for Kuma and Dragon within the Angel Legion. 48

Equipment / Items

• Reject Dial — His primary finishing weapon during the battle against the Red Dog Pirates. 6
• Impact Dial — Used in human-beast form. 43
• Slash Dial — Used in human-beast form and as part of the Angel Legion's standard combat style. 6 43
• Black bandages — Conceal his body and distinctive Lunarian features. 4 6

Relationships

• Annus — Rescuer, commander, and most trusted leader. Diumil follows him with absolute loyalty and serves as one of his closest confidants. 4 41
• Lilith — Fellow officer under Annus. Both enforce Annus's authority, including reprimanding Yale when he questions or disrupts orders. 12
• Yale — Fellow officer and frequent logistical partner. Diumil often acts as the more serious counterpart to Yale's eccentric behavior. 12 16
• Angel Legion — Battlefield leader and trainer. He inherited Annus's combat methods and helped turn the legion into a coordinated Dial-using force. 6
• Kuma — Assigned with Yale to develop Kuma's training after Kuma became an Apprentice Celestial Soldier. 48
• Dragon — Assigned with Yale to develop Dragon's Angel Legion training program. 48

Story Role / Major Arcs

Hachinosu and the Angel Legion

Diumil served as Annus's intelligence aide and officer on Hachinosu. He assessed the Red Dog Pirates as appropriate live opponents for new Angel Legion recruits, then personally ended the battle by defeating Sakin with a Reject Dial. 6

When Annus foresaw the impending collapse of the Rocks Pirates, Diumil organized supplies, treasure, Dials, processed clouds, and the Angel Legion's assembly for the withdrawal from Hachinosu. Annus ordered him to lead the legion and attendants to Water 7 because Diumil's identity was too sensitive for God Valley. 12 16

Water 7 Operations

At Water 7, Diumil guided Lilith, Yale, Alice, Teach, Shanks, and Shamrock to the concealed shipyard while disguising them and checking for surveillance. 37

He guarded the shipyard directly, killing masked thieves who attempted to steal Annus's vessels and abduct Lilith. An invisible Devil Fruit user escaped his detection and entered Annus's quarters, prompting Diumil to accept responsibility for the security lapse. 39 40

After being offered one of the Devil Fruits taken from God Valley, Diumil ate it and gained the Phoenix Fruit. Annus subsequently tested and guided his new abilities through a sparring match against a Lightning Clone. 41 42 43

Lunarian Exposure

Diumil's black wings and flames were observed during the Scrap Island battle, leading to the exposure of his Lunarian heritage. World Government agents arrived at Water 7 to capture him, but Sain eliminated them before they could successfully report their findings. 43 45 46

Return to Birka

Diumil safeguarded Annus's Eternal Pose to Birka during the seven years spent in the Blue Sea. He guided the five airships back to the Sky Island and was visibly excited to return to the place where he first met Annus. 50

Trivia

• Diumil is one of Annus's three officers alongside Lilith and Yale. 4 12
• He considers Birka deeply meaningful despite it not being his original hometown, because it is where Annus saved him. 50
• His Phoenix Fruit's blue flames heal but do not burn surrounding wood, whereas his later red flames possess genuine destructive heat. 43
