Please just tell me a normal manga....

Fullmetal Alchemist
Ai no Exorcist
D-Gray Man
07 Ghost
Hakkenden
Nurarihiyon no Mago
Adekan
switch
Dolls
Those should tide you over

Tbh most of those are anime plus I've watch them all sorry you couldn't help

Utsuro no Hako to Zero no Maria
Baccano!
Horimiya
Blame!
Monster
Code:breaker

Well, i hope you can find something you havent discovered yet (=・ω・=)

If you don't mind reading (slight/mild) shoujo manga, then I really recommend Dengeki Daisy... though it has some really difficult technical terms in it, the overall story is really good and the characters are very lovable.
Hmm, I really like Iris Zero as well (also, Horimiya!) and Bokura wa minna Kawaisou, Kawaii Hito by saitou Ken
And though not a manga, it still has a nice story: Unordinary.
All but Dengeki Daisy are still ongoing though, so...
I hope you like these or that they sparked your interest

Try it'is long. Ice Cold Demon's Tale. It is one of my fav's. slow at first , but the story picks up no yaoi. The writer also did Silver Diamond.

Where can I find Utsuro no Hako to Zero no Maria?

Thanks so much everybody you helped me a lot

Pfft sorry I accidentally replied to someone saying thanks so much blah blah when I was trying to say it to everyone well here's my thanks
