After the Serpent kissed Kuro and bit his lips , he got a swollen mouth . I think the Hobbit girl has to suck the poison out of Kuro's lips , kinky , lol .
Reading chapter 31 - Dryad again gives me a lot of insights :
The dryads were kissing , that means they were actually mating . They were angry because they were c0ck-blocked , lol .
The male Dryad already poured all of his "pollens" inside the bodies of females , so when Senshi cut his head , no pollen was left inside his body .
Dryads mate with their mouths , so their bodies do not have no d!ck or pu$$y ( but why do female Dryads have big boobs ? )
