The narrative hook—waking up in a strange place with no memory—serves as a powerful blank slate for both the character and the audience. In Black Summoner , Kelvin discovers that he didn't just lose his memories accidentally; he actively bartered them away during his transmigration to a fantasy realm. This choice defines his journey:
: His first follower is Melfina, the very goddess who orchestrated his reincarnation, though even her face remains a mystery to him initially.
The "memory loss" trope is frequently used to allow viewers to learn about a world's rules alongside the protagonist. Other series explore this differently:
: Kelvin trades his past existence for the rare class of "Summoner".
