Rias's adventure in a world full of Pirates

After losing to Riser, Rias makes a delusional wish, dealing with a short depression, and the next day she tries to get over it. After her dream somehow gets granted. While her maids prepare the wedding dress for the ceremony with Riser, she disappears shortly before trying it on. She lands on an island surrounded by ocean. Maybe she'll even find true love who knows.
