Check out Parabellum by Oshare Kyoushitsu
Guy makes homunculus girls, decides to be their dad, but he forgot about the "special ingredient" that a homunculus needs to grow up.
@Rheeve Comparing the comments on Chapter 1 to the comments on this or the previous chapter, I don't see a significant difference in the frequency of a "This is bad because pedophilia" sentiment, or a significant difference in the frequency of the word "pedo" or the phrase "pedo manga". In fact, for both chapters such things were a lot less common than I would have expected.
@redjoker Actually, as far as I can tell she's only a few days old. So not very legal at all . . . although, she'll probably still look like that for the rest of her life, however long homunculi live . . . so eventually she'll be a legal loli, but right now technically she's more like a baby who looks like a loli. It's all way too silly for me to care, but just saying.
