Ash

A Chief of Staff of the Nameless Legion and younger brother of Dust, Ash is an extremely powerful dimensional monster that has fought with Alpha Queen Jisu Seo.

Personality
Ash claims to be the smarter one of the two siblings. However, UNION describes Ash as cowardly, though he does not display this outwardly, and describes Dust as the cunning and more dangerous foe.

History
Ash and Dust used to be a single immortal entity known as the 'Searing Wind' before Jisu Seo split them into two and made them mortal. Ash and Dust eventually have a rematch with Jisu, seeking her out at her own home in Gangnam. The pair later claims to have killed Jisu, but in reality, merely sent her to the external dimension.

Due to the return of Azazel, after the events of David, Ash and Dust aim to regain their powers as an immortal entity. However, as this requires one of them to die, the siblings then begin to act against each other, using Jisu Black as the tool to carry out their plans. When Jisu Black awakens as the Omega Queen, Ash and Dust both present their proposal to Jisu Black. Dust promises to leave the Wildhüters unharmed, while Ash promises to return Jisu Black to normal. Unfortunately for him, Ash's proposal was not as appealing and he is killed by Omega queen. He is chided by Dust for not understanding love, the basis for Jisu Black's decision, and his powers return to Dust, reforming the original powers of the single entity. During his final moments, he mentions his regret that the last face he sees is not Sylvi's.
