Larva

Larva (ラヴァ Rava)***

A Shinma from the western world. In the OVA, Larva comes to prevent Miyu's vampire blood from awakening, but it does anyway, for she drinks his blood when he drops his guard. As a result of this failure, Larva's face and voice are sealed behind a mask for all eternity. In the TV series, Larva faces Miyu after she has become the Guardian. After he has struck her down, she drinks his blood. In both cases, Larva starts out as an unwilling ally, but later pledges to be by Miyu's side because of her sorrow, something he was able to glimpse at during both blood-bond scenes.
Larvacan use his nails to slash things and (in the TV series) he can also wield a scythe. He is very powerful, as he is seen to win against every shinma without getting mortally wounded.
Unlike in the OVA, in the TV series and Manga, Larva can speak and will occasionally remove his mask. The name "Larva" is taken from Roman mythology, which like "Lemures" refers to a restless spirit of the dead. Many of the Western Shinma appearing in the second manga series also follow a naming convention drawn from various European demons and spirits. Larva's name and signature mask may also have been inspired from the white, ghostly Venetian Carnival mask "Larva," also called "Volto." In Volume 1 of the TV series, Larva was called Lava in the English dub and subtitles. The following volumes referred to him as Larva.
