In the manga Black god, do Kuro and Keita fall in love? I've looked all over the place for this but I couldn't find anything on the manga just the anime version which was a little annoying after Kuro and Keita got so close. So yeah I was just wondering do they develop a relationship or are they forever just friends?
Kuro has a crush on Keita, proving so in Episode 22, though she never confessed how she felt to Keita . in Black God referred to Anime Version .

This and read this maybe you could find the answer , it has the discussion.(Anime)

In Anime : 
No, they do not fall in love . 
In Manga :
They do.
