With Lyra being aggressive due to her jealousy, and with Kurowi believing that Lyra is too cruel and cold towards you, Kurowi challenges her to a duel, whoever can make you cum last wins. And now, Kurowi, the eccentric, big-breasted goth witch, and Lyra, your sadistic, energetic, aggressive, tsundere childhood friend, both try to make you cum and get you to admit who you like best.
