Summary:

Right or wrong, perspective dictates much of the public awareness of anything and everything.  This perception is not limited to whether something exists or not, but many other qualities.  A poorly informed piece of popular media can make wild animals seem more or less dangerous than they actually are; misrepresent scientific fact as fiction or vice versa; or even vilify decent people.

It was the perspective of the student body of Minegahara High School that cast Azusagawa Sakuta as a dangerous, violent individual.  Whether the rumor of the infamous “hospitalization incident”, where he allegedly got into a fight with and sent three classmates to the hospital, was true or not didn’t matter.  With so many of his classmates perpetuating the rumor, most of the student body treated it as the truth.  Likewise, it was the unspoken agreement to respect the privacy of Sakurajima Mai that created an environment where polite people had to actively try to ignore her if they recognized her in public.

But what about when a single individual’s perspective is the principal factor in how the world perceives them?  Like when Futaba Rio convinced herself that those around her would prefer a slightly different version of herself?  Or Makinohara Shouko’s wish to become an adult when she couldn’t believe she could live long enough to see that future?

With a strong enough desire, these perspectives can take on a life of their own in the public eye, and while not a widely known phenomenon, it is very much real.  From vanishing as if never existing, to creating a doppelgänger of yourself, to projecting your future self into the present, there is a mysterious force that can turn a person’s life on its head without warning, and the public at large continues to operate none the wiser.

Because if the rest of the world accepts someone's perspective as the truth, what is real and what is delusion?

Summary:

Set in the world of "No Time Like the Present" and it's sequal, we have a short new story, Allison's Birthday. Reading those two would be helpful for world-building, but probably aren't 100% necessary.

Follow along to see how she makes the most of it.

Summary:

Two girls pick up a fallen alien object, which explodes in their hands.  This gives them the ability to change their size at will, with no known upper limit to how large they can become.  It also gives them complete invulnerability while at any size, even to nuclear weapons.  When the girls grow, whatever clothing they are wearing grows with them and also becomes invulnerable.

This story tries to address the question of how people would realistically behave under these conditions.  This includes the behavior of the two girls, the behavior of the people who know them personally, as well as the behavior of all of society in general.

The story begins as the two girls reach the age of 18 and decide to finally reveal their powers to the world.  How will society adapt to knowing that the entire human race is now at the mercy of two teenage girls?

Summary:

Trevor´s a man whose two girlfriends found out one thing… he has two girlfriends!

The story begins with all three having a talk. But this is not his fault, he couldn´t help it, he met them at about the same time, and fell in love with both! He was really bad at taking big decisions, before he knew it, he was already in a relationship with, well... both.

They have an ultimatum for him, it´s time to choose, pick one to be his girlfriend. Each of them will seduce him to choose her. To achieve that, they have a plan…

The girls have found out one thing, he´s into tall women, but not just regular 6´ tall, he wants a completely enormous woman to show him her love. That´s why both of them decided one thing, they will undergo a treatment that will make them grow!

Although it´s the same treatment, they grow as quite opposites. One of them finds herself growing into a curvy, plus sized, at some point slightly fat, bbw. While the other lady grows into a more assertive, muscular woman.

Will he be able to choose? It´s hard since he´s very attracted to both! And their growing doesn´t make thins easy...
