From Easy Going Scans:

"Year 252 M.C, in this era which plants are almost extinct and the land is barren, a strange disease developed. 'Shinigami's flower,' the unique lethal flower that carries death." The disease is curable if found in the early stages but if left till transformation stage it becomes lethal and the only option left is extermination. These are all dealt with by request to 'Gokurakuen,' the national medical institution specializing in dealing with shinigami's flowers.

Our protagonist, Doctor Ichinose Souma, is the class representative of Mobile Team Unit Class 1. As his class gets too few requests, he and his assistant Hina often get into trouble interfering with other class's jobs.

During their school days, Rin and Karaku were a detective duo of sorts. One day they meet again as adults, and indulge in a stroll down memory lane together. But what one of them doesn't know is that he is already dead, wandering the earth as a ghost...

The fearsome foursome continue their journey west towards Shangri-La, encountering new challenges and new adventures along the way. Their legend precedes them, but not always in the way one might expect. The Minus Wave that apparently drove all the youkai in the land mad looks like it might have missed one, as Sanzo, Gojyo, Hakkai and Goku meet a lone guardian and the band of children he cares for. Fear and misunderstanding run throughout this particular leg of the journey, including between the members of the Sanzo group!

From Kirei Cake:

The colourful story of Aya, Hina, Kei, and their classmates, trying to figure out the mystery behind Risa's sudden disappearance. It all begins with the discovery that her disappearance has some correlation to the online dating site called "Amore." Hina proposes that they should try out the site first-hand themselves, and upon doing so, they encounter something completely unexpected?!

There is an inn that you can visit where you'll find old things you thought were lost forever.

This is the story of a girl who works as a performer at sake houses, but who has a unique ability. She has a tattoo of an eye on her hand which endows her with the ability of "second sight," and the ability to control dreams and illusions. Though this often comes in handy, it also complicates her life. She is constantly getting involved in situations with various supernatural creatures, such as animal spirits, kappas, and more.

Kokuryuu Kaguya was only a little boy when he witnessed his father murdered by demons. He spent years trying to convince people about what he witnessed, but was dismissed as a traumatized child with an over-active imagination. Now a teenager, Kaguya still remembers what happened.

One day, Kaguya is struck by a mysterious light and meets a young girl named Mao—a skillful warrior wearing bunny ears—who rescues him from a demons' attack, then demands to know what planet he's from! Kaguya finds himself inducted into a secret organization of other-worldly individuals whose goal is to defend Earth from monstrous invaders. Reborn as a Battle Rabbit, strange powers awaken within Kaguya which allow him to fight these creatures and seek vengeance for his father's death.

The one source of hope in her difficult life was her trysts with Leon. But Colette could never be sure if Leon really loved her...
