Got back into watching Outlaw Star, and always wondered about Caster Bullets and their numbering. Anyone got a complete list/set of the number. Do the numbers have meanings besides the bad luck shells?
The numbers of the shells used in the show were 3, 4, 5, 9, 10, 11, 12, 13, 19, along with a shell that was unnumbered.
The Outlaw Star Wikia has a nice page all about Caster shells.
Caster shells are numbered by the wizards who create them. Their numbers appear to define the varied effects of each shell. Shells that are numbered #4, #9, and #13 are the rarest kinds, as they were only created by wizards of Tenrei, Ark Manaf, Hadul and Urt.1
Most shells just draw on the mana stored within them, but those particular shells were special because they consumed some of the lifeforce of the user.
