On a sunny day, during afternoon tea.
"Hey, Master Hong Yue, my teacher at the Witch Academy told me you're a human form taken by some indescribable being. How did you first set out on your travels?" the girl asked the red-haired young woman sipping tea beside a large parasol and a little round table.
"A bunch of shameless humans dug me out of my bedroom while I was asleep. Their leader wanted to suck my blood and eat my flesh. Then Lady Grand Crusader dropped from the sky to uphold justice, and the two of us took down those bad guys together. Later, on our travels, we met you in the forest, when you were still a tiny little thing." The red-haired witch, clad in an ornate mage's robe, set down her teacup and answered.
"That's all there is to it? After you left me at the Witch Academy, where did you travel?" the girl asked curiously.
"That's all there is to it. After leaving you, I helped the Archangel of Death in the realm of the undead with a little task. Then I went to the mages' kingdom and served the current Magic Emperor. But my identity as a different race was exposed, and the mages locked me up in the Sky Garden prison for a while. I won over a few tough cases in there, so they let me out early," the witch replied.
"Pfft!" The girl was so surprised that she spat out a big mouthful of tea.
