Phil was born to be the saintess's guardian.
After falling in love with the saintess at first sight, Phil's life could never again be separated from her.
She hoped the saintess would awaken, and left the village to search for a way to make it happen.
Frai, who had lost her memory, accompanied her along the way and saw Phil's side as the only place she felt safe.
Frai taught her swordsmanship and promised to find the finest sword for her.
But Phil always felt there was something else mixed in with Frai's kindness toward her.
Under that burning gaze that seemed so familiar, she initially thought Frai had fallen in love with her at first sight.
To protect her love for the saintess, she dared not grow close to Frai and treated her only as a friend.
Only when someone pointed out how much more alike they were becoming did she realize that Frai was turning into her mirror image.
"I came to replace you, the version of me with the best ending."
Frai revealed why she had come, but chose to become herself again.
Before the Demon King was sealed away, Phil and Frai in parallel worlds thought of each other at the same time.
Frai, with the worst ending, was forever on the campaign to defeat the Demon King, witnessing her companions die again and again.
Phil, with the best ending, never reached the Demon King, and her companions were always by her side.
They switched souls and went to each other's worlds.
As they exchanged letters, they fell in love, but saw identical faces reflected in the mirror.
Frai was the first to figure out the answer, and lost herself in the best ending.
When she returned to her own worst ending, countless people offered her their blessings, wishing her victory over the Demon King.
Thanks to Phil's efforts, she firmly believed the ending would be different this time.
After the Demon King's seal began to weaken, Frai awoke in a new body.
Rewriting the worst ending became her obsession, and she set out to do it by imitating Phil.
When success was just within reach, Frai abandoned her confession to Phil and ran off to meet her love rival.
"Why does she have that face?!"
