Miko-senpai, Ame discovered upon returning to Japan, was a 'shrine maiden', a kind of sacred sorceress who protected Japanese shrines. But she was also self-proclaimed 'elite', whatever that meant.
Elite Miko could tell the future, read your fortune, and assassinate your enemies, all while talking in incomprehensible, 'elite' English.
However, this very powerful senpai couldn't talk directly to Ame, talking to Kiara while watching her, blushing, out of the corner of her eye.
"Miko-senpai says we'll find what we're looking for in Korea. And that you are her dream type. Out to shoot some hearts, huh, Ame?" Kiara teased happily.
