Eh I changed somethings in black lagoon to fit the code geass universe remember so the timeline may differ remember black lagoon takes place in our world unlike code geas where america doesn't exist. Plus Cornelia was a teen when she was kidnapped so the lagoon crew are a bit older than she is.
yah soon its just takes time to come up with ideas im currently working on a chappy which explains how cornelia met up with lagoon company when she was a teen. Lets just say she got kidnapped by ninjas to ransom her off to her father, Her dad the emperor refused to rescue her saying if she was weak enough to get caught by meer assassins she ain't worht rescuing. I assume this cause of charles survival of the fittest creed.
