"Meisou! Underworld' and "Blood Blockade Battlefront" / "Kekkai Sensen" had a very similar serious tone and dark atmosphere. These two works, despite very different otherwise with former being a promotional short and the latter being a full series, do share the common premise of a powerful evil being taking something precious away from the male protagonist due to him not being able to save someone and special eyes with an unique ability.
