“If you thought I was horrible with how I wished to lock everyone away in the Infinite Tsukuyomi and reclaim chakra for myself, Chaos is even worse. It makes me look pitiful by comparison, but to answer your question it is an entity from my world that desires nothing more than to see the galaxy destroyed and covered in darkness. It doesn't care who it uses or manipulates, as long as its goals are met.I was one of its many victims that fell to its temptation. It tempted with me the premise that I could gain revenge on the one who destroyed my home by becoming its servant. I was a fool for trusting it, believing I was servicing a greater good from what it told me, but then again I was easily manipulated because I lost everything and didn't wish to see my home destroyed anymore. It was only later that I discovered Chaos's deception when it was angered with me for failing to do what it asked and tried to pull me into my mind and destroy me by making me go insane, but being stubborn, I managed to resist and came to accept what I did was wrong and I how I could use my powers to help those who were affected by Chaos and ensure a better and brighter future back in my world, hence my desire to return home and leave the shinobi world alone.Even if I did manage to purge myself of its influence I do not know if those back home would accept me knowing I served their enemy.”
Princess Kaguya Ōtsutsuki is the matriarch of the Ōtsutsuki clan and the Rabbit Goddess who was once truly a good and caring person. However, after obtaining the ability to manipulate powerful chakra from the Shinju's fruit, Kaguya had grown despotic and developed both a god-complex and messiah-complex, believing that chakra rightfully belonged to her alone and that only she could protect and unite the world. Despite her initial desire for peace, Kaguya caved into corruption from her power and lost faith in humanity's ability to do what is right, and opted to use her great and terrible power to submit everyone to her will. Humanity around that time began to fear her as a demon.
In this world, wherever there is light – there are also shadows. As long as the concept of winners exists, there must also be losers. The selfish desire of wanting to maintain peace causes wars, and hatred is born to protect love. Man seeks peace, yet at the same time yearning for war... Those are the two realms belonging solely to man. Thinking of peace whilst spilling blood is something that only humans could do. They're two sides of the same coin... to protect something... another must be sacrificed. Wake up to reality! Nothing ever goes as planned in this world. The longer you live, the more you realize that in this reality only pain, suffering and futility exist.
