I was messing with both songs when I found out that they're both 150 BPM. So I though, "Why not mix them?"
I can't make animations, so I'm leaving you with the "special" OP. (It's been slightly edited to fit the music.)
Original songs:
● Instrumental: "Fukkireta" / "Mischievous Function": pitch +1
● Vocals: "Motteke! Sailor Fuku" (anime: Lucky Star)
