Demon Slayer: Dancing with Butterflies Under the Rainbow

Make up for regrets + the indigenous male protagonist is not a time traveler + the single female protagonist is a butterfly ninja + has special talents + mostly daily life + self-created breathing method Qingkong carries her sister's vision and embarks on the path of killing ghosts. Qingkong: "When I first met Shinobu, I regarded her as the star that I would protect throughout my life!" There is no shortage of sun-like characters among ghost slayers. Ninja composes gorgeous music for the night. Butterflies flutter under the rainbow in the dark night. Flowers and wind intertwine to form a tornado of petals all over the sky. In the dark night, the water blades are as majestic as a tsunami. Xiawu is gathered by the rocks. The fire and the sun are always hot and dazzling. Although the strange pupils are timid, their eyes are always on that lively kitten. A breeze always accompanies them. I hope that the guardians walking on this bloody road can witness the arrival of that dawn.
