The title after the name is just a relation to some uber characters I've made in my Disgaea games. In HoD, she first started out as a Blue Mage, then developed into the Samurai class, with spears as her weapon of choice. In Disgaea 2: DHD, I stuck her to the Kunoichi class, while giving her a strong affinity to ice/water. Every now and then I'd switch her between spears and staves (and rarely swords).
