a (xenoblade)
Character from Xenoblade Chronicles 3: Future Redeemed. An enigmatic person who aids Matthew in his quest to find and save his little sister Na'el. A somehow resemble Alvis from Xenoblade Chronicles 1.
A is actually Alvis "himself". That is, A is the Ontos core's humanity and personality separated into a different body.
As with other non-binary characters, if A is depicted with distinguishable feminine traits, such as breasts or an accentuated ass, then use 1girl + genderswap (otf). Otherwise use 1other if A appears androgynous enough.
