The Angel Of Death
As Nisemono got closer to the guardian's Sekai, he could hear the thunder and sees light flashing. It gave him the idea that Pika uses the lighting. Bravely, he steps inside the guardian's world.
The inside is a plain, just flat with a leafless tree in the middle. There, he notices someone standing on a branch, wearing white clothes, facing him.The lightning and the loud rumbling of the sky doesn't seem to make the young man flinch. There is no doubting it, that someone in the middle is the guardian Pika.
