In the original Japanese, Nathan uses the I/me pronouns "Watashi" (formal gender neutral and informal feminine) and "Atashi" (informal feminine). In several official instances, mainly the English dub and subs of Season 1 and The Beginning, Nathan is referred to with masculine pronouns. As of Season 2, they are referred to with They/Them pronouns almost exclusively. Nathan will be referred to with They/Them pronouns in all instances to prevent confusion.
