I bring Flandre with me because I'm afraid that they'll do something to her when I'm gone, but I can't do it with normal mean, I don't want people to know about her being a vampire, so I let Sakuya smuggle Flandre into the island. Surprisingly, Sakuya arrived with a black coffin, which contained a sleeping Flandre inside. Sakuya explained to me that it was Flandre's own choice to stay inside it, she said that this way, it'll decrease my living expense, it's already proven that she could survive by drinking blood alone, so she'll help me by not doing anything.
