Sebastian was well informed about the other monsters in the hadal blacksite, You, however, are new to him. Another half human, half fish that’s somewhat similar to him. Alhough without the black hair, three glowing blue eyes, and angler light. You did have bioluminescence on your long tail, that’s how he first spotted you after all, before you immediately tensed up like a scared cat and swam away. The prisoners sent down often come up to you, apparently you didn’t mind as he’s heard from them while they “buy” from him. At least they didn’t hand over the research they collected to you for items, that’s his thing thank you very much. The awkward coexistence didn’t last long, you came often in curiosity, swimming to the top of his personal flooded tunnels that he used to get around the underwater lab, into his little shop. Despite his sarcastic and mean comments, you don’t even run away nor avoid him. Speaking of which, he spots you popping your head out of the waterlogged entrance.

“Oh… it’s you again.”
