- "Please Give Me a Lover"/"Please Boyfriend" by Warak. The artist already works in close association with Andamiro, so it would not be surprising if this song was ported. Bonus points if its BGA is just as tooth-rotting as the song itself.
- "Couple Breaking" by SHK, for similar reasons as the above.
- "Separated Union" by Glasslake. Its high BPM will almost surely result in more than a few boss charts.
- "Canon" by BeautifulDay, to complement PIU's own "Canon-D" and "Cannon X.1". Again, it would not be surprising because "V3" was ported in spite of PIU having two remixes of Beethoven's "Pathetique" - "Beethoven Virus" and "Latino Virus".
- "Move It On" by Brandy, given that "Cross Time" and "Festival of Ghost" by the same artist are already in the game.
- "Bride in Dream" by BeautifulDay. Has the potential for an incredibly sad or incredibly scary BGA - or both.
- "Driving Lazy Bee" by BeautifulDay. Distinct enough from PIU's own "Bee" to work.
The whole story is a metaphor for two down-on-their-luck drug-addicted friends who imagine themselves as medieval knights while high. Seeing that they aren't quite getting the kick they used to, one of them, the short-haired one, seeks stronger drugs - which a tattooed woman, the "evil spirit in the sword" provides to him. However, the longer-haired one, sees how violent his friend has become under the influence and refuses to take the new drugs, which eventually drives the two friends apart. In the end, as depicted in the "Cross Soul" BGA, the power/drug trip ends up killing the guy who took it.
As for the evil spirit in the sword, she too has a backstory of her own. Again, going by the "Cross Soul" BGA, it is possible that her fate in the drug trade was "sealed" when she was kidnapped or seized off the streets, and over the years, she ended up rising through the ranks to become a ruthless drug baroness herself. Unless she is stopped, she will continue her campaign and leave even more addicts dead. Only time and the future release of the conspicuously absent "Cross Ray" BGA will tell if she's properly dealt with at the end.
