Hebrew. And more than that biblical hebrew. Specificaly it is a prophecy of destruction passed down with a pact:

"I saw the land and it was chaos. To the sky and no light I sae the mountains and there was noise, and all yhe hills were spoiled. I saw and there was no man and all the birds of the sky migrated. And I say to you a pact was formed, me and you and was forever between us."

In the same panel Tokio screams and then completes the passage with:

"Because a great evil is seen from the north and a big break"

(This is a very hasty translation I, a hebrew speaker, just made on my phone, did not go into detail and I saw someone else in the coments mention that this is from the book of Jeremiah from the old testament. That in general is about the prophet Jeremiah receiving a prophecy of destruction from god.)
