My Guardian Spirit Is Tokisaki Kurumi

I traveled through a parallel world and came to an earth where spiritual energy was revived. This world is full of all kinds of monsters and monsters, In order to resist the invasion of demons, humans use equipment left behind by ancient times to test whether they have the qualifications to summon guardian spirits. These guardian spirits are divided into animal forms, human forms, and semi-human forms. The rarest type among them is the humanoid guardian spirit. I obtained the two-dimensional guardian spirit summoning system, And my first guardian spirit was the nightmare Tokisaki Kurumi.
