Synopses and Details

The story follows Yūri, a high school student who successfully passes her entrance exams, marking the beginning of extraordinary adventures. After an exciting first kiss with her crush, Himurom, things take a strange turn when Yūri experiences bizarre phenomena: water in a cup rising mysteriously and even hands emerging from an aquarium! Initially dismissing these occurrences as mere imagination, she soon finds herself spiraling into a world far more perilous than she anticipated.

Eventually, during a date with Himurom, Yūri is engulfed by a water puddle and transported to the ancient Hittite Empire. This twist transforms her life into a thrilling journey through time and history. The charmingly illustrated panels and captivating story promise to enchant both new and long-time fans of the original manga.
