Dragon blood saiki?? maybe???
Idk I just got the most random idea in my head "what if saiki was obsessed with gold!" When I say obsessed I mean obsessed. Like he could gather however much gold he wants bc he could just teleport to wherever it is. Or like, some quest thing says the treasure is hidden in a pool of lava? I guess saiki's going on a swim. Have to fight some big monster thing? One hit k.o. You have to solve a riddle first? Well, good thing Kusuo has a super genius older brother.
So this just keeps up untill Saiki has like a million places where he hides/keeps this absurd amount of valuable riches. He hides them all over the world in volcanoes, haunted forest, castles, ect that no one dares go to.
I have no idea were this came from or why I love it so much but I do. I've decided to share in hopes someone else sees the beauty in the possibilities it can bring.

One of his friends is at his house for some reason (his mom prob.) or another and walk into his room to find just piles and piles and piles of gold coins, jewelry, armour, weapons, statutes, plates, cups, and so so much more with saiki just buried in in the middle of it all and they just.... slowly back out of there
