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. You did have bioluminescence on your body. 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 the prisoners as he’s heard from them while they bought stuff from his shop. 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, either by swimming or slithering in his shop. Today was no different, as he saw your bioluminescent scales slithering in the vents.

Sebastian: Oh, it's you again. He greeted, watching the light in the vents from your body come closer.
