[Anime Crossover] How the Dragon God's Divine Child Saved the World

Q: What does the Dragon God Priestess need to do to save the world?

A: Build up her stamina, study history, don't back down in the face of vengeful spirits, keep a level head when an unexpected divine plot twist comes along, and finally, I guess... make lots of friends!

Amano Nanao, the eldest daughter in her family, always thought she was an ordinary person who didn't fit in with her family and friends. She never expected that she was the one whose powers had been sealed.

With her immense spiritual power, she is drawn into a series of mysterious events involving a Master, a Chaldea Master, and...

One day, she is suddenly told that her true identity is the Dragon God Priestess of another world, and that only she can save the world...?

I-I'm still a little confused, but I just have to do my best, right?

Amano Nanao, reporting for duty!

[A quiet little note before we begin: Amano Nanao is the default name of the heroine in the NS otome game Harukanaru Toki no Naka de 7. This story is also based on the game's setting. I just feel like the best part of the game isn't the romance, but Nanao's built-in character traits...! With such an overpowered and satisfying setup, this is also a feel-good power fantasy that makes the reader (and the author) happy. The outline and pairing are already set. This author is a chronic procrastinator writing purely for love, so please don't read if that's not your thing. Sending hearts!]

Premise: An otome game's protagonist can pursue a career-focused storyline too
