Grim Reaper

Grim Reaper (死神) was an unknown enemy that appeared in Mass for the Dead from the Chaos Zone.

Appearance
The reaper's face is expressionless like a mask with a iron spiked halo rising behind its neck. A looming specter like entity cloaked in a velvet robe, with a wavy white collar. The only areas besides its head that were exposed are its mid-section which is narrow revealing a bandaged waist and its seemingly automaton limbs.

Personality
The Grim Reaper shows little to no personality whatsoever. Although that is the case, it was identified as a male by his prey, as it never said a word. So far, its sole objective was to kill Seiya Ryuuguuin and his comrades. Interestingly, the entity seemed to have prior knowledge on Valkyrie and her destructive technique, going so far as to single her out, deeming her to be the greatest threat.

Background
The Grim Reaper's past is unknown, as are it origins, though Seiya Ryuuguuin believed the entity to be some sort of being that lived between various dimensions.

Mass for the Dead Arc
The entity appeared when a Crack forced its way into the Divine Realm. Seiya Ryuuguuin sensing the danger of the unnatural portal managed to ground himself with a sword and prevented his comrades Valkyrie, Ristarte and Adenela from being sucked into its pull. However before they could handle the situation, the entity made its presence known and launched an attacked from within the Crack at them. It's attacks destroyed the sword that was holding them down, allowing the Crack to pull the goddesses and hero in as a result.

After being pulled into the Crack, the four found themselves in the Great Tomb of Nazarick, where they were placed under its custody until Momonga could determine a way to send them back. Later the four journeyed to the Great Forest of Tob to hunt for provisions as Seiya refused to accept the food present in Nazarick, paranoid that it was unfit for human or goddess consumption. At the same time, the group aided Solution Epsilon, Narberal Gamma, Slimeko and the protagonist in subduing the Chaos Beasts emerging from the local Crack. After the monsters were subjugated, Valkyrie impatient to return back to the Divine Realm, decided to unleash her power and call a [Gate] through an Order to Ishtar hoping that the veteran goddess would be able to hear them and grant them a way home. Instead of an [Gate] appearing, the Crack reacted and the entity that was lurking in the Crack from before appeared once more and attacked Valkyrie. Seiya theorized that the Order which Valkyrie made had helped it to pinpoint their location. The group try and battle the thing, but it easily dodges or withstands all their attacks without injury. It also prioritized attacked Valkyrie, interfering with her methods to use her powerful attacks. In face of this threat, Seiya orders a retreat and uses a [Meteor Strike] to cover their escape. The attacked created a crater where the Grim Reaper stood, but the entity was unharmed.

Later Momonga and Seiya formulated a plan to destroy the creature. They moved battlefield to an open plain and implanted several time stop countermeasures to prevent the Grim Reaper from using its powers. Sadly it when it came it displayed that it was equally fast without its temporal abilities and continued to attack the goddesses and hero. After a while the Grim Reaper concentrated all its attention on Valkyrie trying to eliminate her. His focus left it blind to an attack by Seiya who utilized [Valhalla's Gate]. the very same attack that the Grim Reaper was stopping Valkyrie from completing. It was summarily enclosed within the spell and impaled to death finally ending its threat.

Abilities and Powers
According to Seiya, he suspects that the Grim Reaper to be an existence similar to Crossed Thanatos. This reaper appears to have the ability to cross dimensions given it was able to navigate to locate a target through a Crack. It also appears to have power over time, allowing it to stop it to appear and disappear in an area, though its limited to one hour. Its spatial ability seems to be largely unaffected by the Crack phenomena that normally interferes with spacial transfer techniques. Even when not using it temporal abilities the entity is capable of fast flight and is lightning fast that even a member of the Pleiades admits is hard to track. The entity was also documented to be resilient and strong, able to withstand multiple magical and physical attacks by deities and several powerful agents of Nazarick and come out unhurt.
