So for my theory... Lol
Hmmm so there are three variables?
1 human of the night
1 human of the moon
Vampires.
My guess is that Ken is the human moon? If i remember correctly mr. Vampire refer to Ken as his Sun? My guess is he's like a sun/hope when he can only thrive in the darkness?
If mr. Vampire is really the first vampire ever. Then he's the one who stole the moon's life. My theory is that when he is still a deceitful monster. He was also drawn to the moon's kindness(beauty? or immortality?), He was actually jealous not of the moon's power but because moon care for humans. But then his greed unexpectedly took away moon's life and he's actually suffering by only surviving on human's blood at night (i mean how ironic right if that's the case, a monster who hate humans now need their blood to survive; only thriving at the night where the MOON is just above him, engulfed by DARKNESS/NIGHT ). And no matter what he is still drawn to the moon, even the human moon, Ken. (lol if this is the case, i pity you, just come to me vampire hottie)
And i think Agia is actually the person who was deceived leading to the death of moon.
Human of the night i think is gonna be someone else. Or maybe Agia will get an upgrade to become the human of the night? I just think he's not really it right now.

Woow the art and plot is really good and the d is exquisite hahahha thank you uploader-san (づ ̄ ³ ̄)づ.
I don't really get why utsumi had a sudden change of personality that night... My guess is that he's gay and has a hidden violent personality caused by a traumatic past?
I think after what he did to blondie (which he can't remember), he did it again with saeko guy or something else went wrong, but i really think he also did something.
And those guys who attempted to rape blondie, i think his superior (the old dude on the phone in ch.2) is the one responsible. Maybe the intel's from him, and he knows blondie want to bypass utsumi? and will go to the shrine alone. I think the old dude has an idea of the wrath blondie has for utsumi. I mean why would he ask if blondie's getting attached like it means something??
I think this will get deeper than in currently is. Looking forward to upcoming chapters! ლ(´ڡ`ლ)

I'm getting the feeling Akamine had a previous partner (maybe just a work partner or a lover or both, maybe that Saeki guy) who dumped him hard or died or was straight and never knew Akamine liked him, and he mistook Utsumi for the other one that night he raped him. And in that last panel he was remembering the previous relationship. That's just a vague theory though.
Well, i prefer him being accused of slutty homo rather than being done publicly (eventho he's a very shitty and a killer, being raped is just too much lol but i think he deserve it). Well he seduced ci nian's man before and then accused/sabotage him of killing his gramps. So I agree to tingting's idea. ╮( ̄▽ ̄)╭
