The time-travel heroine is a 17-year-old mixed race. She has been frail and sick since she was a child, but has an extremely strong personality. She never bows her head and admits defeat. She pursues the first place in everything. However, she has no choice but to suffer from a terminal illness. However, her unwillingness to admit defeat makes her choose never to bow to her destined fate. A car accident caused her to travel through time and space with the help of the God of Death and the demon Astalu. After rebirth, she embarked on a journey through Japan's Edo period with the mission of changing her destiny. I personally experienced the rise and fall of the Shinsengumi, and witnessed the imprint of the samurai spirit of heroes such as Okita Souji, Saito Kaede, and others in that bloody era. This era belongs to the era of heroes and beauties. The singing of love will definitely transcend life and death, and travel through ancient and modern times. . . . .
