Dia, the "smaller" light-haired girl, was MC's magic tutor when they were little children
Talt, the "bigger" light-haired girl, is the one MC rescued from starvation in the woods and groomed to be his right-hand
Macha, the dark-haired girl, is the MC rescued from a shady orphanage while MC was in his merchant persona
Both Lugh and Ilg is the MC. Lugh is the assassin. Ilg is the merchant persona.
