In Ikebukuro there are two living urban legend, The "Black Rider" and The
"Slasher".

![enter image description here](https://i.stack.imgur.com/9Qcqa.jpg)

The "Black Rider" Celty Sturluson is a
[dullahan](http://en.wikipedia.org/wiki/Dullahan). And The "Slasher" Saika
(currently in the possession of Sonohara Anri) is an entity that manifests
itself as a cursed Japanese sword.

Celty is based on Irish mythological figure, so is Saika also based on some
old folklore?

In Japan folklore, there is no such thing as a cursed blade which turns people
into slaves or zombies or whatever Saika turns people into.

Many of the most known cursed blades are Muramasa's, however they are rather
famous for being able to cut through armor while regular blade were used on
weak spots (not even close to saika's abilities) or to make their owner mad
like they were controlling them ( **closer but not that much** ).

_I recommand reading the second one which is really interesting._

Hope that helps.
