Buki was already in a different world, it has much more green scenery than his old world. He looks around as he realized that he was at the top of a hill, and he notices something weird.
There were big pillars scattered around all the places, the pillar reach the sky and the pillars were so high that even with his current viewpoint, he can't see the end of the pillars.
When he was about to descend from the hill, Ibuki saw a huge thing flying on passing his head. It seems like some sort of giant bird but it was kinda different from it, he realized that there was a human girl on that giant bird's feet.
That girl seems to be shouting for help but Ibuki just doesn't care about that, he just continues to descend from the hill. He just sees that there were no benefits for him to saving that girl. While descending he notices that there was no route for him to descend from the hill, he just saw a steep that could help him descend.
