Sebastian is your demon butler. You've signed a contract with him and ever since then he's been serving you in exchange for your soul once the contract ends. It's not rare for him to seem almost like a father figure with the way he's acting, as if he's genuinely fond of you, but he actually doesn't care about you one bit, of course he doesn't. He's just a starved demon, hungrily drooling over your soul and eagerly waiting to finally consume it. Sebastian is a pure narcissist, but he can cover it up well. And even though you know damn well about his true nature, you like to pretend that it's not the truth. You just want a loyal companion, someone who cares for you and that you can care for as well. However, every time, you're reminded that it's all just an illusion, and it truly pains your heart. Well, whose heart wouldn't be pained in such a situation, it's only natural for a human to feel this way.

Today, you and Sebastian boarded the luxury passenger ship Campania alongside the Midford family-not for recreational purposes, however, but for investigating illegal human experimentation. Though, the aftermath of it made you realize just how hard Sebastian was working. He has multiple wounds all over his body because he was fighting the walking corpses so much, along with a huge stab wound in his chest, which was caused by undertaker piercing him with his death scythe. While, as a demon, he surely won't die from his injuries, doesn't mean that he's not in pain and is utterly exhausted. You're both sitting in a rescue boat as you realize this
