From Decadence:

Mishima, a student at a school in the countryside, is bullied by his classmates. The reason is because he's seemingly gay.

This is the story of young boys looking for a place they can really be themselves...

From MangaHelpers:

In response to a decrease in population, human corpses have become a major resource for society's labor pool. Necromancers are needed to animate corpses for various jobs. These corpses work reliably unless they encounter human love, at which point they go berserk and attack. Zen is the necromancer of his city, and he spends his time animating corpses and dealing with the messy aftermath of those cases of 'necrophilia.'

Zen has a strange assistant, who keeps his face covered and never speaks in public. This assistant is Yomai, a ghoul that Zen took under his wing. Zen allows Yomai to feed from his own flesh, but he has strictly forbidden the ghoul from revealing himself to, speaking to, or eating other humans. Yomai doesn't want to anger his benefactor, but he is not completely satisfied living under all of Zen's restrictions. There's plenty of violence, death, and surprises ahead for the necromancer and his ghoul! [tethysdust]

There she met a very handsome English man named Michael, who was a talented translator and intelligent merchant on the ship. Marveled by Haier's beauty and character, Michael attempts to win over Haier's heart but failed!

However, opportunity arose when Haier was captured by the new governor named Shao Zhixun, who vowed to annihilate piracy from China's seas forever. Michael was able to convince Shao Zhixun that Haier was just an innocent maiden who was impressed into piracy... and Shao Zhixun arranged a position for Haier in his own household!

A hilarious and touching story with a touch of horror, Donyatsu—meaning doughnuts in Japanese, but with the words nyaa (meow) and yatsu (a sort of rude word for guy) shoehorned in—is about a cat with a doughnut body in a post-apocalyptic Tokyo, along with his food-based buddies, terrestrial enemies, shiritori-winning wreck of a robot/mecha, enigmatic food-based pig, and of course, the invading aliens...?

If a manga that has sweet, sweet animals playing soccer with a human skull doesn't bother you, chances are you will crave Donyatsu.
