Well, it's possible. Special hiatus for returners can make the story more interesting by creating anticipation or allowing for character growth off-screen.
I'm not sure specifically as I haven't read it in detail. But generally, a light novel might be about a story in a magical world with unique characters and their adventures. It could involve magic systems, quests, and character development.
Since it's a light novel about returners and magic, the main characters could be those who have returned from a different place or time with special powers. There may be a character who is initially reluctant to embrace their role as a returner but gradually grows into it. Another character could be a powerful mage who has been waiting for the returners to come and fulfill a prophecy. Together, they make up a diverse cast that drives the story forward through their interactions, conflicts, and collaborations.
Well, that's a tricky one. It could be in a particular chapter or section related to a specific event or character arc. You might have to do some thorough reading to find it.
The magic of a returner is very special in the manga. It has diverse and complex manifestations, and it plays a crucial role in driving the plot forward. Also, it gives the characters a distinct edge in various situations.
