really my fav are anyone with those huge over exaggerated boobs... they could be used for pillows.. all the kami that aren't loli/childlike are good to me

my original favorite was brynhildr cause i love her design, the short black hair and glasses, her H scene is nice she has decent skills, she's a good healer, she give off that kinda mature and caring vibe
hermes was my 2nd fav, cause these are 2 partners i had early in the game XD hermes has one of the best H scenes to me, she makes such cute faces and her voice is nice

fav kami in general- Brynhildr
fav kami for voice - Amon (i love her more deep and serious and kinda quiet tone, unlike all the other screaming high pitched girls)
fav kami for H scene - Tezcatlipoca (cause milk, oh how i love milk..)
fav kami for battle- Tyr (the stun ability is awesome)
fav kami for design - Shiva (she's so pretty )

bonus kami that I love... amaterasu....cause she have a love for BL....
