Bloody Moon

Bloody Moon is Jeanne's version of Pillow Talk, like her other weapons, is recolored to match her sense of style, but still maintains the same combos and techniques as the original. At the end of the keychain attached to its hilt appears to be a plump red cat.

Trivia

 * Bloody Moon's name is a reference to a Blood Moon or "Hunter's Moon" which is so named due to the full moon being a grim crimson/orange color that's bright enough to allow people to hunt even at night. Notably, such a phenomenon also occurs as the result of a lunar eclipse and is said to herald-times of great change, further tying into its themes of Jeanne and the Umbra Witches.
 * With its talks of transformation and with Jeanne also going under the nickname Cutie J, the weapon also references the popular anime and manga series, and its heroine of the same name, Cutie Honey.
 * In Bayonetta 2, Bloody Moon is mentioned in the description for Jeanne's Cutie J outfit from Bayonetta, however, the weapon itself is not in the game, though Jeanne's sword Angel Slayer is.
 * Both Pillow Talk and Bloody Moon, through their lightsaber-like design and their attacks, most notably the charge enhance and the secret Moon Slashes, are reminiscent of the weapon wielded by Hayato Kanzaki of Capcom's Star Gladiator, and his special attacks, Ashura (where he extends his plasma blade through empowering it), and Engetsu (performing a circular readying motion before delivering a powerful downwards slash that sends out a shockwave of energy).
 * The Jupiter, the Bringer of Jollity, an Angelic Hymns Gold LP, which is needed to unlock this weapon is a reference to Ayaka Hirahara, the singer of the theme song of Okami, "Reset", whose debut song is named "Jupiter".
 * In fact, the music of Angelic Hymns Gold LP of Jupiter is actually an arranged BGM of Ms. Hirahara's "Jupiter".
