Debitto

Devit is aggressive, impatient and more dominant than Jasdero. He frequently takes the lead during their arguments and battles, although neither twin can use their most distinctive ability properly without the other.

He enjoys taunting opponents and approaches lethal battles as entertainment. His confidence becomes particularly pronounced when the twins believe their combined form has made them unbeatable.

Despite their constant bickering, Devit's connection with Jasdero is fundamental. Their power literally depends on thinking together, making their sibling bond both emotional and supernatural.

Devit and Jasdero embody the Bonds of Noah. Their Materialization ability makes a shared thought physically real when both twins imagine precisely the same thing.

They use matching guns to focus this ability. Bullets fired simultaneously can manifest whatever phenomenon the twins have agreed upon, allowing them to create effects far beyond conventional gunfire.

The twins can also combine into Jasdevi by simultaneously imagining what they consider the strongest possible body. This fusion possesses greatly increased physical power and can manipulate its long hair as a weapon.

Devit and Jasdero serve the Noah Family and participate in the conflict surrounding Noah's Ark. Their principal opponent there is Arystar Krory III, who remains behind so his companions can continue through the Ark.

The twins use Materialization to subject Krory to increasingly dangerous attacks, eventually combining into Jasdevi when their individual bodies are insufficient.

Krory's parasitic Innocence continues fighting through his blood even after his body appears incapacitated. The resulting attack badly injures Jasdevi and leaves lasting scars on both twins.

Devit survives the Ark confrontation and continues appearing with the Noah Family as the war with the Black Order develops.

Jasdero is Devit's twin and inseparable combat partner. Their Noah ability requires synchronized imagination, and the brothers can merge into Jasdevi by envisioning a single ideal body.

Arystar Krory III becomes their principal opponent inside Noah's Ark. Krory's Innocence-infused blood continues attacking after the twins believe they have defeated him and leaves both brothers severely injured.

The Millennium Earl leads the Noah Family to which Devit belongs.

Road Kamelot and Tyki Mikk are fellow Noah and members of the family with whom Devit fights against the Black Order.
