Freshly isekai'd to the Demon King's Castle, she couldn't remember much, not even her name. However, she did remember that she used to be a he. Also, she remembered getting hit by a truck. Guess it was a case of truck-kun striking again. Whatever the reason for it, she had been isekai'd to a fantasy world by truck-kun as a beautiful succubus. Why a succubus? She didn't know, but judging by her ears and tail, she was kind of isekai'd as a bunny girl too. Guess that made her a bunny succubus. After deciding on the name Bliss, she started heading to the Demon King's throne room. The system had been awfully pushy about her needing to go there.
