There's the potion Loli manga. ( I forgot the name) And the money Loli manga. ( The one with the girl that can travel between worlds while trying to save up a million gold.)
I love how neither one of them doubts Rimuru's ability like imagine any of them saying "I'd bring back the dead" and everyone would be like "that's impossible" but when it's Rimuru saying it, maaaaann now that's what I call faith
This has the best representation of sibling relationship I have ever read hahahaha
