Description

People used to call such unfathomable abilities "superpowers".
Through the discovery of a certain particle during the end of the 20th century, however, the mystery surrounding these powers was solved, with them and their users now being referred to as "Astral abilities" and "Astral users", repsectively.

Arihara Satoru is an ordinary person living in this extraordinary world.

However, that is but a facade.
Hidden beneath the surface, Arihara Satoru is actually an Astral user working as an agent under a secret organization!

His newest mission:

"Infiltrate this school geared towards Astral users as one of its students!"

Along with his little sister, Arihara Nanami, he succeeds in the infiltration and blends in with the students there without a hitch, building a rapport with fellow classmates Mitsukasa Ayase and Nijouin Hazuki as well as upperclassman Shikibe Mayu along the way.

Having not drawn even the tiniest bit of suspicion, his mission continues according to plan.

--Or so he had hoped. Due to an unforeseen event, his true identity was revealed to Mitsukasa Ayase!
But the revelations didn't stop there; Ayase's own big secret was also revealed:

What do you know! Her chest was padded!

The two now held each other's unspeakable secrets within them.
And with that one encounter, their fate would be forever changed--

Description

Nanami is Satoru's little sister, however, they hold no blood relation.

She's a sweet girl who excels at every aspect of housework. In terms of personality, she's rather placid and subdued. She tends to be shy and reserved when first meeting someone, but once she warms up to a person, she can be rather friendly.

In the organization, Nanami acts as Satoru's partner, providing him back-up during missions. Despite the fact that she frequently bashes him for his rash decisions, she loves him dearly and does her best to look after him. Little known by others, she also has a bit of a chuunibyou side to her.

Description

Ayase is one of Satoru's classmates.

She's cheerful, responsible, and is loved and admired by everyone. After she was interviewed as the result of a certain newsworthy incident, she became somewhat of an internet sensation as a result of her looks.

Her bust size is E--that's what her bio says, at least, but that's a size she can only reach through extensive padding. Her breasts are truthfully a very modest size, so E-cups are nothing more than a pipe dream for her.

Her personality, like her breasts, is also fabricated. The real Mitsukasa Ayase is a bit lazy, moody, and prefers shutting herself in her room over hanging out with others.

Description

Hazuki is another classmate of Satoru's and she also happens to be the manager of the dorm he lives in.

Her personality is best described as rigid. She's very duty-bound, and highly values rules and proper behavior. That, combined with the fact that she's the dorm manager, means that she often has to scold students for things, but they don't hold that against her.

She's very well-respected and well-loved by her peers. She's also a very big fan of historical dramas and owns a respectable DVD collection of them.

Description

Mayu is an upperclassman of Satoru.

For a certain reason, she's purposefully stalling her graduation and repeating years. Usually calm and composed, but there are times when her more childish, attention-seeking side sneaks through.

Mayu has her own personal lab at the academy, which is where you can usually find her doing research on astral abilities. She's very good at making coffee and takes great pride in that skill of hers.

Description

Chisaki is a first-year student at Kikka Academy and a classmate of Nanami's.

She's incredibly bright and outgoing, which is seen in the fact that she made quick friends with someone as shy and antisocial as Nanami.

She has a bit of a complex regarding her small body, which prevents her from wearing more mature outfits, thinking she won't look good in them. However, she still enjoys looking fashionable, so she takes great care in selecting her wardrobe. Her keen interest in fashion also means that she enjoys giving advice to others and helping them choose outfits.

Description

Kyouhei is a classmate of Satoru's.

He's friendly, outgoing, and doesn't have a trace of timidness in his personality. He's generally pretty upbeat and kind, but the one thing that always gets him mad is when people mistake him for a girl because of his baby face and other feminine features. That being said, he's perfectly comfortable with the way he looks.
