A man, with a troubled past, ends up as a teacher in Kivotos. Oh well, it's not the toughest thing he's had to do. (A retelling of the story with a different Sensei)

When Sensei woke up one morning, the last thing he was expecting was a call from Rin. Even less so about an urgent, secretive topic. Little did he know it would be just the first step in unravelling an insidious mystery looming over Kivotos, and the ones behind it.

One night, Koharu approached Sensei for a request. She called him to an empty room, dimly lit, mostly by the moon light. She undressed and asked one question. "Sensei, can you grant me this one wish?" As so it began the moment where they were only man and woman. With lust and desire clouding their minds.

After having arrived at Kivotos, Sensei finds that this seemingly futuristic society is more like the outside world than he thought. As he comes to understand his new surroundings, he finds himself wishing to mend the pain of a girl who has been by herself for a long time...

A look into short little stories that the Kivotos students might experience in their hectic bullet and explosion filled daily lives.

Sin was a nebulous concept at Trinity, having shifted and changed over the years. Peeping in on the girls' changing rooms was probably sinful though, and as such it was no surprise when one male student was sent to the cathedral to be purged of his sin. Only, the process for that was more intimate than he anticipated. [Smut]

Accompanying the Abydos girls to a faraway, secluded beach, Sensei takes the opportunity to have some alone time with Nonomi - enjoying both the shade, and each other. [Smut]

Being a teacher means having students to teach, to guide towards the future. As flawed as he was, that was what he was used to. A trip to the ruins near Millennium hasn't changed that, but now he has to raise a robot who looks like a young girl into becoming human. He'd usually have somewhere to start, but what's a teacher to do for a 'student' like this?

"We never imagined angels will grace us in these desolate rainforests. Perhaps we need a mental evaluation. But at this point... this war has gotten us so numb, a bunch of teenage angels appearing on Vietnam out of nowhere is nothing but just another bullshit thrown at us."

A collection of one-shots between Sensei and various girls from the game. Rated M just to be safe.

It wasn't uncommon for Mari to work alongside Sensei at Schale. One day however Mari has something very important to tell Sensei, and when an unexpected accident brings them closer, Mari finds it in her to tell him the truth. [Smut]

Finally having some privacy in the library, late at night, Ui decides to indulge in a particular desire of hers - though she never expected to see someone else there while she was doing it. [Smut]

Shiroko likes to ride at night - with the wind in her hair, and a toy in her ass.

Oneshot. Amau Ako asks Sensei to visit her again. Trapped in the Prefect HQ by the night rain, they digress again and again in a comedic downward spiral of Ako's thought process until they reach a critical point, and Ako makes a decision.

Black tar memories over the water. It floats gently knowing nothing but darkness. One day, light may shine through but for today, there are hardships to go through. This is a collaborative fic dedicated to the OC of HEXIGONE set in the world of Kivotos. Will you proceed through her relationship story?

Having lost most of his companions in a gruesome war that's still fresh in his mind, Palus Viotto, a young mercenary out of place, out of time, with no way back and an unfamiliar voice requesting his help. This torn contractor alongside his ragtag crew dives forward into Kivotos, a deceptively utopic city garnering new challenges.

In her haste to get to school, Yuuka left plenty of "evidence" behind of last night's fun.

With a meteor shower due to happen, Sensei and Nodoka take to the roof of the Schale building to admire the sky and stars - when some mumbled words lead to them becoming more intimate than teacher and student. [Smut]

There is no time like the present. But you shouldn't just forget what made you the person you are today, Sensei.

As the designated advisor of SCHALE, Sensei is responsible for handling the arising issues within Kivotos and its academies. Meeting various students along the way, he sets off to solve these issues with their help while also setting aside time for his students. This is primarily an observation of Sensei's daily life.

The more desperate one gets, the worse one will be become. The treaty had failed, yet everyone remained smiling. However, the embers from the treaty will continue to burn, bidding its time for a return. Thus, in the views of many, of Nagisa, a proper clean-up had to be done, thoroughly, and by the one held responsible, Mika. [Heavily based on Volume 3]

Mashiro had a certain appreciation for high places. Always wanting to indulge his student Sensei took her to higher and higher places until they went to the highest in Kivotos - the Schale Executive Building. They weren't going to just do some sight-seeing, though. [Smut]

Finally putting aside his work Sensei takes a moment to comfort his secret lover Yuuka; said comfort becoming something more intimate. All whilst four of his students spy on him from various locations, perving on him and Yuuka as they go at it. [Smut]

Getting a text from Kayoko wasn't unusual. Getting a text asking him to come around to Problem Solver 68's office was. By the end of it though, he was glad he went. [Smut]

Sensei didn't expect to get a visit from Hina on Christmas Eve. He also didn't expect her to ask him for help... or that, by the end of it, both would end up in the same bed. [Smut]
