How come? It say's it in this part:

"Azazel continue his question and asked what is the purpose of Loki and the people of the other world in this time.

Zen told Azazel that the Evil God from the other world, the evil gods and deities thought that they would be able to write their own ending if the change the history of the world.

Kurenai added that they intend to change events surrounding his father Issei and his aunt Rias.

Kurenai continued that in their timeline―― in the future, there is a person that can observe parallel worlds from the world line. The world line is safe but it is seems to have already stepped away and its history was changed.

Zen said that in a  certain world line, the seirei of Chichigami did not appear (sounds familiar? *cough*BorN*cough*) . The presence of the other world will not be noticed if not for making contact with Chichigami."
