That's why I

don't know Nito. (originally だから私はにとなんて知らない)

Just take revenge on Kaguya, I got a immortal body. (originally ただ輝夜に仕返しをする為に不死の身体を手に入れました。)

That night, I was supposed to kill Iwakasa and take the Hourai Elixir from him.

Nito doesn't come off as having changed my destiny... (originally にとは私の運命をねじぬげたりなんてしていません、と)

...otherwise... (originally そうでないと)

she would have disappeared from my memories... (originally 私の記憶の中のにとさえも、本当に無かったいとにされてしまうから)
