10

While Mina, Yuki, Veratos, Nanami, and Yuzuru enjoy a day in the indoor pool at the estate, Akira secretly spends the day with a flirtatious Mei Ren. Later on, they walk through a garden where Akira notices cleomes, which only bloom at night. Mei Ren tells of a tragic story about a butterfly that was in love with a cleome until its death. The message of this story entails that a butterfly will never be able to bond with a flower. Veratos abruptly receives a call that three ships are approaching the Vampire Bund. Mei Ren states that the reason for her time with Akira was to assess of his memory, recently-restored and currently-lost. Mina tells Yuki not to tell Akira about the Three Clans, but Yuki notifies him anyway. The Three Clans, led by Rozenmann, Ivanovic, and Li, visit the Vampire Bund, questioning her nobility status. She is forced to marry within her lineage to produce an heir to the throne. The leaders of the Three Clans send assassins after Akira, putting his life in grave peril. The wager is to see if whichever assassin can successfully kill Akira by daybreak, then their respective leader will be chosen to be the husband-to-be. Mina is told that Akira is that of a different lineage and life span, making him unsuitable to marry. (Source: Wikipedia)
