"I am willing to enter reincarnation with you and suffer all the sufferings in the world in exchange for eternal life and never be separated again."
"I would like to transform into a sword spirit, cut off all darkness, and protect you."

Dreams reappear in reality,
Fate leads us,
Who else remembers the promise made under the cherry blossom tree and beside the stream...
