Because of Honkai's meddling, Kiana closed her eyes and opened them again to find herself in an unknown world. Her companions from her original world had been swept along with her. To find the companions who had scattered to who-knows-where, Kiana had no choice but to board the Astral Express and search the universe for them. But before she could find all her most important companions, she came across counterparts who looked just like them. There was a little cuddling, but not much. After all, they were all good friends. A little cuddling was no big deal, hehe. …"We're all good friends…" Raiden Mei simply smiled and exchanged a glance with the woman beside her, known as Acheron. It was as if the two had reached an understanding. The women standing behind them, all more or less similar in appearance, gazed at Kiana with obscure, stubborn looks. Then, the very next moment, an unspeakable... custom-made collar settled around Kiana's neck and locked firmly in place. "So it's only natural for good friends to do a few intimate things, right?" A scent that clouded the mind swept over her. Someone's touch, and the soft laughter of various women, filled her ears. What kind of good friends would do something like this?!
