水晶玉と伝説の剣 (Tankobon Hardcover)

The visions add so much mystery and tension, but I wonder if that was planned from the start or developed during writing. How did it shape the story's direction?

The fantasy elements were so vivid, but the romantic subplot felt like it was waiting to blossom. Was that intentional to keep the focus on the quest?

The magic felt both wondrous and believable, but I’m curious whether the rules were mapped out first or evolved as the story unfolded.
