Nope she doesent read manga, she got 3 years to repair moon and you say is universal? 3 years for a little moon? Kidding me? Medaka verse dont reach even star, even the girl with complete arsenal because all ability she has has been created or having from sameone who create that ability with metapotence, so she has ability exist dont all ability, also op ability are more conceptual and ambiental manipulation so no direct power, also medaka even she copy who got complete arsenal dont reach universe, because najimi isnt universe and most op ability are like become a star or be a black hole, now black hole with a radius of human body cant even destroy the solar system, become a star is even lower because she can only evaporate water around but a star of human area is really little, we can create little stars in labs even they arent at human size we are still alive so, universal is great hyperbole, also even plot or narrative ability are limited because she say he cant use because of author and she live in a manga etc... , if u know medaka cosmology you need know all jump narration exist together even dragonball,naruto etc... and they cant use narrative power because they are limited from real world (jump force explain all jump manga cosmology)
