Why not create a fanfic where Yuna enters the worlds of 'Jujutsu Kaisen,' 'Tower of God,' 'Chainsaw Man,' 'Tensura,' 'Overlord,' 'The Beginning After The End,' 'Solo Leveling,' or 'Mato Seihei no Slave'? Additionally, you could make a spin-off about Yuna when she started her cultivation journey in her original world.
