A semi-scarce character type in some stories, anime, manga, or video games. One of these characters' backrounds would be that he served his lord, but died for a cause (e.g. Shaman King's Amidamaru).

These characters technically appear in these stories in their 'deceased' form. This form may be a ghostly body (transparent with a ghost 'tail') Or the body would appear 'demonic' (e.g. Genpei Touma Den's Kagekiyo, who has a demonic-looking face and white skin).
