Wait I cracked the code! The reason Ryoshu gets well with Sinclair so much isn’t just because he can translate her lazy abbreviations but also because he is childlike enough for her maternal side to make her try to protect and teach him. If you remember, she did threaten him in mistranslating her at one point but in Canto VII when we were gonna fight the Fanghunters she congratulated him when he mistranslated her shouting for them to shut the fuck up
