Erica always says things that are difficult to understand. Is the best way to describe her is weird or eccentric?
In her mind, our world is in constant danger due to manipulative beings or mysterious origins. She believes that she is the only one who sees the truth and tries to save the world in her own way. Maybe this is her special way of seeing the world.
Erica certainly doesn't seem like a member of the Heretics Investigation Division of Lumopolis, but I feel like I understand why when I see her with Florine all the time.
A kind reminder, you must never underestimate Erica because of her nonconformist thinking and free spirit. There is no doubt that Erica is a strong helper when fighting enemies.

There are countless unknown existences in this world.
Before the age of seven, I, like other ordinary children of Lumopolis, lived a monotonous and boring life under the guidance of my elders. My grandfather was a stern knight who supervised my training every day. My only pleasure was to sneak under the covers at night and read a book that my rebellious father had brought back from outside, a book called "One Hundred Thousand Inconceivable Things."
It was in this book that I discovered clues left behind by an unknown existence.
The book contained a ritual to "summon the ruler of another world." I was very curious, so I tried it out, but I didn't expect it to really work. A deep voice echoed in my room, asking me "What do you seek?"
I fainted with fright, but my father found me right away and took me to the hospital. Since then, I have been convinced that unknown existences are always watching the world.

Our world is being watched.
Ever since I discovered the unknown existences, I began to think whether the God of Light we worship in Lumopolis is one of them. I found my answer when I entered Dawn Academy. Those who believed in the God of Light created many burdensome rules and boring doctrines. We had to pray sincerely before and after meals and also partake in other strange behaviors. Everything has been predetermined, and the mastermind behind all this was the God of Light, one of the unknown existences who watch this world. And I am the only one who is not controlled because I have awakened!
After realizing this, I was finally convinced that the God of Light must have unknown designs for this world, so I must find a way to save the world. However, I am surrounded by people controlled by the God of Light, and I will be in danger if my presence is detected. Without a choice, I had to imitate the behavior of others, hide my intentions, and wait for the right moment.

I met President Florine after joining the student council of Dawn Academy. She comes from a poor family and became the president of the student council through her own efforts. Although she has not awakened as I have, she is a trustworthy person.
Probably because of my perfect disguise, she was very friendly to me, cared about me in every way, and even helped me with my classes. We studied together, ate together, and after a while, could even talk to each other about anything.
President Florine was the one who told me about the Heretics Investigation Division. I was intrigued when I heard that I could conduct research freely and would have access to ancient ruins.
It's possible that those ancient ruins buried in the earth may contain crucial information that can reveal the truth of this world and save those who have been controlled by the unknown existences!

Since you know all my secrets, as a person who has the ancient bloodline of the Caelestites, are you willing to save the world with me as my captain?
Unknown existences stare at our world all the time and manipulate innocents from the shadows. Our world will be doomed if we follow the script they wrote for us. They created the Eclipsites and attacked us, and what we need to do is to rebel against this predetermined destiny.
To do this, we must retrieve the lost technology of old civilizations. This Colossus is the crystallization of the technology of the old civilization. It can take us anywhere to explore ruins that no one else has discovered. Let us inherit the legacy and technology of those who came before us and retaliate against the unknown existences that covet our world.
