Dancing in the Lotus Stream

[Alternate world + ensemble cast + single protagonist + high-fantasy war + battlefield + powerful protector guiding the way] "No golden finger, and the protagonist isn't invincible. Fans of wish-fulfillment stories, please move along." Sigh, this boring life is getting to me. These servants are all so dull. All they do is bow their heads and call me Princess. They won't even play with me. Well, in that case, I suppose I'll have to sneak out and have fun on my own. Sigh, I won't be able to play for much longer. I heard the servants say Father has found me a master to teach me magic, and they'll be arriving soon. Once that happens, Father will keep me under close watch. So annoying! Whatever.

I'll try one more time. Let's see what's really going on here. "I'm not good at writing introductions. Please head to the main story, dear readers."
