Egg of World ~Illusory Lilium~ v.2.02

There are two worlds in which the film takes place. One half of the world is a cityscape identical to that of the present day. The main character, Mari, was a student living an ordinary life with her friend Kotone. That day, they went to school as usual, enjoyed their club activities, and went out to the town to eat sweets…… as they were supposed to do.

Mari, the only one unaffected, is led by a voice to put on a mysterious costume. Mari, completely unaware of what was happening, wielded her weapon and easily defeated the monster.
After rescuing Kotone, Mari is summoned to the facility, where the men waiting for her tell her about the existence of another world, and the existence of the miasma and monsters that flow in.

Mari, who has a strong resistance to the miasma, is one of the few people who can fight the demons head-on.
