Tanya Degurechaff is a reincarnated Japanese salesman-turned-sociopathic child soldier, forced by the almighty Being X to fight an endless war.

But soldiers need to eat, too. So join Tanya as she samples fine wartime meals.

Inaba Yuushi's parents passed away when he was in his first year of middle school, forcing him to move in with relatives. Though they did care for him, he could tell he was being a burden. After graduation he was all set to move to a high school with a dormitory, but said dorms suddenly burn down! It's tough finding lodgings as an orphaned student with little money, but Yuushi somehow manages to acquire a room in a nice old building close to the train station.

Of course there's a catch: the place is a "youkai apartment," where humans and supernatural creatures - ghosts, mononoke, oni and the like - live next door to each other. A friendly high school sophomore named Akine lives there as well, but not only is she completely unfazed by the monsters, she can even exorcise evil spirits! Looks like Yuushi's new life is going to be much stranger than he bargained for...

The story follows three elementary school girls: Sako, Koko, and Miko. They live an ordinary life until their new teacher starts a bizarre lesson on awakening their special powers.

The side-story of "Youkai Gakkou no Sensei Hajimemashita", set 1 year before the events of the main story, following Maizuka Mamekichi's first year at Hyakki Academy.

Serialized on Pixiv Comic.

4-koma about a "human" girl attending what turns out to be a school for monsters.

One day, at the base of Mt. Fuji, appeared a "castle" pouring out Youkai. To curb the labour shortage caused by a declining population, the government decided to integrate the Youkai into society; however, this led to rising conflicts between Humans and Youkai.

In response, the JSDF, with aims to expand their influence in public security, secretly forms a Youkai penal tactical response force, "Tachikawa Task Force", to execute "tactical solutions" for the various issues born from this new society.

From Hokutonogun.com and HappyScans:

A former professor of archaeology, Hieda Reijiro was expelled from the Japanese Archaeological Association for claiming that youkai exist. Ancient horrors come to life before our eyes as the youkai hunter wanders the land to find proof for his theory.

The included one-shot, "The Living City", won the seventh Tezuka Award in 1974.

N/A

Hieda-sensei is a professor of archeology, with a fervent belief in the existence and power of supernatural creatures such as gods and demons. Since he can't prove anything, his belief has earned him the mocking nickname Youkai Hunter from his colleagues.

One day, two men from Ootori-chou come to visit him. They're planning to promote tourism by reviving their town's old, traditional Demon Festival, which was discontinued a century ago. They're basing the festival on Hieda's research, although they're changing a few details to make it flashier for modern sightseers.

Although Hieda is troubled by the history of human death associated with the festival, he agrees to attend as an advisor. When the Demon Festival turns out to be much more historically accurate than anyone ever dreamed, it will take all of Hieda's knowledge and courage to help set things right!
