the quest that outlives death

This is a story of if Himiko found a book after the killing game that Kiibo wrote from his lab (I forgot to check of he ever entered his lab but just pretend he did if he didn't) and it's a book of 13 riddles that lead to a spell to bring people back to life, so now Himiko is going on a quest to find out how to do the spell and bring her friends back to life. Will she succeed? Or will she join her friends instead? Human Kiibo AU but they think he's a robot and he might be someone's sibling. (I'll update as much as I can also they might not act the same as in the game, I'm not the best at making them act the same)
