Eyewitness ~The Case of the Prophet~ (目撃者 ～予言者の場合～) is a special short story given to those who purchased volume 16 of DanMachi in Gamers.
Summary[]
During the Goddess Festival the Miach Familia set up a stand with the help of the Hestia and Takemikazuchi Familias to sell products. Daphne questioned the idea of selling diluted potions, but Naaza argued that it was in fact a new product, Potion Lemonade.
However, while her familia dedicated to selling potions, Cassandra was lost in her memories of her date with Bell. She couldn't stop thinking about how fantastic it had been for her and how Bell had behaved differently than he usually did, unaware that Hedin forced him to do that as practice for his date with Syr, or that the boy had done the same with many other women.
Her sweet thoughts were interrupted when she remembered a prophetic dream she had the night before in which a seductive witch rubbed her cheek against a fluffy white rabbit over and over again until she ended up devouring it. At that moment Bell and Syr walked past the Miach Familia's stand holding hands. Daphne and Naaza briefly talked about it until they saw Cassandra collapse on the ground.
Before her consciousness faded, the girl regretted her stupidity and not having tried to prevent her prophetic dream from coming true because she had been too excited. With tears in her eyes, Cassandra was so shocked that she quickly lost consciousness.
