I just thought about this and it occured to me, and I won't be doing this but I'm wondering, If someone were to app Asch from TotA when he arrived would he remember his name as Asch or as Luke?
TSUBASA SPOILER O+O
Also if someone were to app "Fai's"/Yuui's twin, Fai, how the heck would that workout? Cause I think maybe that would cause some paradox in the rules of memories concerning names.
