Black Black Lotus

After transferring to Fuyou Girls’ Academy, Matsuoka Renna reconnects with her elementary-school classmate Mayuzumi Kyouko. Known by the students as “Black Rose-sama” and the object of their affection, Kyouko says she has worried about Renna ever since Renna left town after a particular incident. Renna, however, is troubled by something of her own. Amid their reunion, news breaks of Black Rose’s death. Shocked by the announcement, Renna receives an invitation to “Black Black Lotus,” a website for suicide matching.
