Duel Against Kaito
When Kaito Tenjō arrived at the top of tower, Diana told Kaito to Duel her if he wanted to rescue Ruri. She Fusion Summoned "Moon Protector", activated its effect to Special Summon "Protector's Shield Token", and Set a card. When Kaito brought out "Galaxy-Eyes Cipher Dragon", Diana activated "Protector Adoration" to negate the effects of "Cipher Dragon", Special Summon two "Protector Shield Tokens", and force "Cipher Dragon" to attack all "Protector's Shield Tokens" or be destroyed at the end of the Battle Phase. When "Cipher Dragon" destroyed all the "Protector's Shield Tokens", Diana activated the effect of "Moon Protector" to decrease the ATK of "Cipher Dragon" and increase her own LP by 800. As Diana brought the ATK of "Cipher Dragon" down to 600, she wondered if there was any point for it on the field until Kaito brought out "Neo Galaxy-Eyes Cipher Dragon". She then watched as Kaito took control of "Moon Protector" and Released it to bring back the original "Cipher Dragon". She panicked as both dragons attacked her directly, defeating her.
