In the Moonlight Circuit Manga that I am currently developing, it will include 2 Dead Apostles chapters. I currently have an idea of how it's going to be made.

Enhance - It is difficult to know what he looks like, from I researched it said he looked like a Devil May Cry character. I saw an illustration of him looking like Lancer from fate but had nothing with the "badass vampire killer who does what he wants" vibe. So, I'm going illustrate my own version of him. A mixture of Nero from DMC4 and Zero from Vampire Knight. He is 18th rank of the Dead Apostles.

He is not to be confused with Tsukihime 2 character.

Story goes that a vampire outbreak is happens in a rural town where Oki is sent to investigate. He meets up Enhance and the two start a rivalry. Enhance escapes and Oki is left collecting information to his base.

Merem Solomon - His beast creatures take a damn long time to illustrate. Ranked 20th of the Dead Apostles. >.>

Oki is given a task to go treasure hunting, he eventually meets up Merem who is also after the treasure. The two are in conflict, when Merem is surprised that he is actually "wounded" by a human and this drove him to get serious. Oki will eventually receive help from an unexpected ally.
