I'm cool with specifically the Castlevania games being sorted under C. They all only have one English title and the Castlevania name started migrating back into Japanese in the 00s anyway, plus how AO3 handles the entire mess is inconsistent in the first place. (Harmony of Dissonance gets to be sorted right...but Lament of Innocence gets an 悪魔城ドラキュラ it didn't even have in Japanese added on because ???)

Shin Megami Tensei's another one where the non-English characters could get dropped, but it's not nearly as inconsistent about it as Castlevania.
