Some interesting picks all around ^^
Not my idea of cute but whatever floats your boat right ;3
Honestly though, I have only seen the animation and cg of Raiko's scenes from the DMM version which unfortunately are censored. I haven't seen or read the dialogue yet but judging from the scenes themselves, I can only imagine good things (ღ˘⌣˘ღ) If I could scavenge the dialogue from somewhere, even it's from the DMM version; as long as it's Hiragana, I could/would read it.
Hmm, if we are to name multiple favorites, my second pick would be Gabriel for her overall appealing design but I also really grew fond of her when I heard her voice and moans in her scenes which are also very lovely to say the least ( ̄﹃ ̄)
Well if it's a different third scene, I don't know what else it could be besides a story related one.
