Stranded, summoned, reincarnated.
These were the three methods for other-worlder to come to this world.
Of the three methods, reincarnation was the least common. Otherworlders who experience this will gain memories of their previous life when they got their god's blessings. These other-worlders will not have black hair because they have accepted the mana of this world from a young age. Some scholars at the academy argue that they are not other-worlder because they were born and raised in this world.
