you should fix that, it's great fun (except when it's like, deadly serious in a way that feels way too surprising for a show that is otherwise extremely fun and silly and goofy also what the FUCK, who let Naisho 12 happen, imagine bringing this home to your kid and coming back to them bawling their face off)
it is kind of long (seasons are all like 50eps, then there's the OVA season, Naisho) but it's worth it
you should probably watch Dokka~n after Naisho too
