"Memento Mori" :
An object kept as a reminder of the inevitability of death, such as a skull.
Memento is the 2nd person singular active imperative of meminÄŤ, "to remember, to bear in mind", usually serving as a warning: "remember!" Mori is the present infinitive of the deponent verb morior, literally "to die". In other words, "remember death" or "remember that you will die"
Well, i could still put more about it, but i think it's obvious that my comic has a strong bound to death.
The choice of the title "Memento Mori - Sins" comes from the fact that "Memento Mori" is the creed of the protagonist who's a women during the prohibition era that have become a contract killer and "Sins" because of the rotten nature of the world in which the story takes place (Crime, corruption, murder and so on ...).
