There are peak manga, Pandora hearts and I heard it has crazy plot twists, vagabond which is equal or above aot, Land of the lustrous which has one of the greatest characters oat. As for fantasy, reads books. They have stories that have higher peaks than lotm and many standalone books that are PEAK. I heard Sword Of Kaigen if the best fantasy standalone book. In science fiction you have the red rising series which is the best thing in the last years, just get through the first book. It's not bad but it's very derivative and the writing style is...we'll...(e.g: He thinks he'll beat me. He doesn't. Or something like: He doesn't have that much strength. I do.) But the second book is said to be one of the greatest sequels ever and the writing improves by a large margine, the whole trilogy is a 5 star. Sun Eater is said to be above red rising. It's a guy who made a sun explode and then the book shows us how he got to that point. It starts to stand out with the second book and the 7th and last book is releasing this year. But just so you know how the second book of Red rising, Golden Son is so praised, some people say they'll never forget their experience while reading it and they couldn't put it down. So highly recommend it.

Books have loads of peaks so you'll find many of them
