Synopsis

Illya and her friends arrive at the beach alongside Shirou and his friend Issei Ryuudou. Whilst enjoying the beach, Miyu tells about how she has a brother, who Shirou resembles, before the girls come across Bazett, who is working part-time jobs to pay off her debts. Later, as everyone has a party to celebrate Illya, Miyu, and Kuro's birthdays, the celebrations are interrupted by some noisy construction from Rin and Luvia, who are attempting to dig for the eighth card, with Illya soon finding herself in the middle of an outrageous feud. Things become more troublesome when Ruby tries to inject Shirou with a love potion, though Sapphie soon sorts things out by erasing everyone's memories.
