The research entitled Because they look like girls or act like girls: erasure of non-binary identities in translations of the Houseki no kuni manga analyzes five translations of the referred manga - two professional translations, one into English and one into French ; and three amateur translations, one into Portuguese, one into Spanish and one into English - and how they dealt with the non-binary gender of the characters. The objective was to examine the ways in which cis-heteronormative ideologies and hegemonic translation ideologies can lead to the erasure of LGBTQAI (plus) identities. The analysis of the data showed that all the translations to Neo-Latin languages, as well as the amateur translation into English designated a gender to the characters. In the case of Neo-Latin languages, the analysis of meta and paratexts suggests that the grammatical gender of these languages played an important role in erasing the non-binary gender of the characters. However, there was also evidence of the influence of cis-heteronormative ideologies in the choice of translation strategies employed. Among the translations analyzed, only the professional translation into English did not designate a gender to the characters. However, the analysis of metatextual sources revealed that translation ideologies related to the idea of fluency were behind the translation strategies used, resulting in a translation that maintains the non-binary gender of the characters, but does not make it visible. By studying the cis-heteronormative and translation ideologies that underlie the translation strategies employed, this research contributes to understand how LGBTQAI (plus) identities can be easily erased in translations and propose ways to make them visible in order to fight cis-heteronormative hegemony.
