There are Moe characters whose youth and innocence attract a fanbase of sexual lust in spite of an author's intentions and then there's these characters who are meant to appeal to Lolicon tastes. Girls (and occasionally boys) who ascribe to this trope are invariably Older Than They Look adults, or supernatural beings that are Really Seven Hundred Years Old. The narrative takes great pains to remind the audience that they are adults, thereby (poorly) attempting to justify the sexualization of their apparent innocence and youth because they are technically adults, and therefore that (supposedly) alleviates the reader of possible guilt.
