Saviors are ranked as well.
The lowest-tier saviors are inefficient. They take years or even decades to save the world once, causing countless people to suffer. However, they may not truly save the world.
The third-tier saviors are manipulated by schemers their entire lives. They are ignorant and naive, just like puppets on strings.
The second-tier saviors pay a huge price to save the world. They may lose their spouse, suffer a disability, sacrifice their friends, and suffer many other hardships. However, in the end, they only receive a useless title or even an epitaph.
"These saviors have tragic lives. I don't want to become like them, I want to be a top-tier savior!"
"What a top-tier savior is?"
"Light-speed salvation!"
"No casualties!"
"Obtaining insane profits!"
"Using the present sword to slay the near future, strangling the apocalypse in its cradle, acting entirely on his will, and collecting the reward he deserved!"
"That's what a top-tier savior is!"
