“ | My true wish? To dismantle this world. Why? For the fun of it. Anger. Sorrow. Despair. Nothing else gives me the same kick. They're my pleasure and joy. I want to watch the residents of some inconsequential world be torn apart... That's all. That's right! This Spirit amalgam's falling apart the seams! Can you believe the information of just one man made me fall from grace?! You may learn from the true nature of his evil and alien madness! | „ |

“ | Nightmare was right. I was innocent at first. But then it took one single drop of venom to make me what I am now... to tell the truth... I feel better now! What do I look to you? A beautiful girl? Perhaps an ugly, misshapen monster? It's too bad I can't tell. | „ |

Kaguya Yamai, later revealed to be Spirit Amalgam, was the main antagonist of Ais Catastrophe, a crossover campaign of Date A Live from the 2017 mobile game Is It Wrong to Pick Up Girls in a Dungeon?: Memoria Freese.
She is an amalgam of Spirit information born from the mana of all Spirits that Shido Itsuka sealed. She later becomes obsessed with Isaac Ray Peram Westcott, which led to her personality becoming his.
Like the real Kaguya Yamai, she is voiced by Maaya Uchida.
What Makes Her Pure Evil?[]
- Merged her personality with Westcott's of her own free will.
- Teleported the heroes of Date A Live (Shido, Tohka Yatogami, Origami Tobiichi, Kotori Itsuka and Kurumi Tokisaki) to Orario.
- Has Liliruca Arde pretend to be Yuzuru Yamai (the real Kaguya Yamai's twin sister), and the false Kaguya would plan to kill her in cold blood.
- Took the form of Kurumi, attacking a group of adventurers that the Loki Familia sent and eventually killing them.
- Manipulated the Loki Familia for them to become enemies to Shido and his Spirit friends.
- Implanted a Sephira Crystal on Ais Wallenstein, which led to her becoming an Inverse Spirit during her battle with Tohka.
- Finally shows her true colors after her plans were exposed by Kurumi.
- Later absorbed the Sephira Crystal of Ais, becoming an Inverse Spirit. She then begins to cause spacequakes around the planet, killing millions to test her new powers.
