SaiSai, it's ultimately about Rape. Or intent to Rape. "Chuu chuu lovely muni muni mura mura purin purin boron nururu rero rero" are all onomatopoeias that are actually sexually explicit. "In that suticase if a coil of rope, packing tape, and a cutter knife" - just denoting the weapons intended for subjugation. "The moshing of the stalkers of undeniable tendencies starts right here!" - Since they use the word moshing and use stalkers in plural, this is about gang rape. It's all throughout the song. So, to answer your question, no, it's not 'obvious this is talking about how hot he thinks a girl is' because that's not what the song is about.
