so i got this idea after reading a harry potter/pirates of the caribbean fanfiction, and remembering a fanfic i made a long time ago on my original account, this is a harry potter/mouretsu pirates crossover, with a bit of space battleship yamato and...
offered during the pirate meet at hideout and accepted
ships security: holland novak/salia tereshkova
salia is the primary chief of security aboard both the yamato and arcadia, but holland through his military experiences acts more in an advisory role, though he still puts the work in like everyone else onboard
ships helmsman: talho yuuki
ships engineers: makoto hyuga/shigeru alba
although the don't mess with the engine itself unless on the yamato they do keep the rest of the ship intact and functioning
ships gunner: asuka langley soryu
she also acts as security for her captain when needed
