Pervert: Uuu... (scared "Whit in hell do I do now?" sound)
Pervert: Uuuuu...
???: Nakutsu-- Nakutsu-- oriri no. ("Oriri" is "getting off.")

Pervert: Aah! I'm getting off!
Pervert: Move it, move it!
SFX: Wata wata

Soou: Ke! Oshiri panpan. ("Ke" is a sound of disgust and contempt. "Oshiri" is "butt" and "panpan" is "slap-slap"; draw your own conclusions about what Soou called the pervert.)
SFX: Ke! Ke! Ke!

Wordless glance

Soou: Aitsu no shogorai ni odoshi-kaketa. ("I started to threaten that guy's guardian spirit." - ???)
Naoki: ......... That was effective. (sweatdrop) But a little petty. (sweatdrops)

Pervert: (I'm not going to try to translate this one for now. He does call Soou a hippie.)
Pervert's side comment: Ei, ei, I'm an idiot!
SFX: Muuuuuuuuuuuuuuuun (gloomy, sulking)
Spirit's side comment: Even though you say things like that... ("...you're going to do it again anyway" is probably what it's implying.)
