It was all so amusing to watch... So much delicious drama...
A Vampire traveled to Shinkai Shigai and began to deface property and destroy statues, then leave. She returned sometime later to do so again, but this time with an accomplice who could summon monsters. Instead of causing harmless mischief like the Vampire, the Summoner begins to kill innocent citizens. Before any major damage could be done, an unseen voice calls them off. Someone must have tried but failed to stop him, because he returns and begins the total destruction of the entire city. During which a Ghost of vengeance is created which kills the Summoner violently.
A Demon, once the Boss of the city that was once here, New Vegas, travels to an island and attempts to attack a young female Ghost. Another Ghost appears, possibly her father, and summons a monster, and together they are all able to drive the Demon off. The Demon appears to be headed toward Shinkai Shigai around the time the Summoner is fighting the Ghost of vengeance.
The same Vampire that started that bit of drama with Shinkai and the Summoner was herself killed on this same island, beheaded by a Vampire Hunter. This Vampire Hunter was not long afterward killed himself by an Angel with a large gun. The Angel then resurrects the Vampire.
This Angel, who has many guns, boldly declares that he will destroy the Demon's city if it does not show itself for attacking the female Ghost on the island, possibly one of his relatives. After a brief period of time, the Angel lives up to his promise when the Demon fails to show and uses one of his guns to destroy everything in just 1 shot.
The Demon appears on the beaches of the island, seemingly unfazed by the destruction of it's city. The Demon attempts to have his way with a young girl, who is a mix of 2 different species. An Angel, possibly the son of the Angel with the guns, intervenes and kills the Demon in an effortless fashion.
A relative of the Vampire Hunter appears and attempts to have his way with a young child in a large city full of sky scrapers that is surrounded by a magical field. He is driven off by the Angel with the guns, possibly the Boss of this city. The relative travels to the island and tries to have his way with the young female Ghost, but is killed by the older Ghost and an Angel, possibly related to the Angel with the guns in some way.
A young Human wearing a mechanical suit with a strange unknown power creates a web of confusion so that he may steal files from cyberspace and not be seen doing so. The person he steals the files from is the Angel with the guns. He sends 2 species, a Tiger and a Dragon, both formidable and war tested, to deal with the Human. The Dragon, who thought the human was "no different than a knight with an enchanted suite of armor," and the Tiger, who thought of humans as "Stupid, pitiful beasts, Barely evolved, half mutated forest apes that think they ruled the world" both seemed to think that throttling him would be easy but didn't count on the Human managing to land a hit - even though it is claimed to be a harmless one - on them both, leaving them incapacitated while the Human escaped unscathed. So delicious.
A Vampire encounters this Human in the mechanical suit soon after. She chases the Human through the streets of the giant city at implausible speeds, and manages to convince the Human to return with her to the building that was the home of the Angel with the guns... The drama begins to thin here; the only drama of interest afterwards had to be the beating of bank robbers in an attempted hold-up...
She licked her lips in anticipation of what was next. With as entertaining as it all was, it was fine to only watch, rather than get involved directly.
