From Yen Press:

It’s Noh-A’s first day at Amityville High School, and her reception is chilly to say the least. Brutal might be a better description! Decapitated but not dead (or is she??), Noh-A quickly realizes that nothing is as it appears at Amityville High where paranormal creatures battle for supremacy. Caught in the crossfire, Noh-A may have to rely on the unlikely (and possibly unreliable) aid of the most sinister student at Amityville… the deadly Jack Frost!

From Storm in Heaven and one of their legacy groups, Bamboo Feathers:

Year 2022 A.D. At a time when anyone can travel around the world, there are more crimes occurring than ever. To protect the country from political terrorist attacks, a new Security System Garrison was created 8 years ago. To destroy this organization, terrorists have started aiming at the leaders of the Garrison, the Instructors.

Seven Instructors have already died in the line of duty, and to avoid another death, the 8th Instructor, Ishikawa Haruka, was given an assistant who would also act as his bodyguard. Iwase Motohisa, previously the Prime Minister's SP, falls in love at first sight with Ishikawa during a chance meeting, and then asks to be assigned as Ishikawa's assistant.

The gentle virtuous housewife used to be a leader of the gang?! After attacked by assassins and her husband got kidnapped, the gentle wife becomes a gangster again to defeat her enemy fiercely with bravery (to save her peaceful life with her husband).

As the towns and cities grow, the people who have Ascended to immortals disguise themselves as mortals in the cities, part of them can’t help themselves but to devour humans, but other than these cases showing up in headlines and on the news, there aren’t any other effects.
Because of this, monsters and demons are almost extinct, and Gods rarely descend to the mortal realm. In the mortal realm there are Ascended who know the rules of the mortals, but few still disrupt those rules, Gods descend to deal with demons from time to time.
Even though some Ascended do descend to the mortal realm as they miss the realm, they still do have their own goals to achieve, so the Heavens sends Guardian Gods to return those Ascended, and also to keep them from harming the mortal realm…
