From JanimeS:

The world of Siesta is set in fantasy Europe where there are people called bullet users who were discriminated against badly for reasons unknown to readers as of volume 1.
The discrimination has gotten much weaker due to Grande Corp's efforts to wipe out the decades-old pirate faction with the help of Bulletron, a battle suit designed exclusively for bullet users.

The story begins as the protagonist Dia Canto tells you a little bit about herself: how she became an orphan, how she met her foster family, and how she is very much in love with her step brother, Loe. However, her affection toward Loe is brutally crushed before it would even bear fruit and she goes out to vent her sadness. This is when she encounters Cid Leon, who she would ultimately be paid to "protect".

The emotions between these two are fresh like a strawberry and sweet like a cup of milk tea. Love is blossoming all over this campus!

Fushimi Inari has a hopeless crush on her classmate Tanbabashi. One day, while trying to interact with him, she accidentally humiliates him in front of the whole class. He refuses to accept her apologies, and, to make matters worse, she discovers that he probably has a crush on their incredibly cute classmate Sumizome.

She has all these things in mind when she is summoned by Uka-no-Mitama-no-kami, a pale fox goddess. In return for rescuing a little fox-spirit creature before school that day, the goddess offers to grant a single wish of Inari's. Without thinking, she blurts out that she wants to be Sumizome. As one might expect, this wish does not go nearly as well as Inari had hoped, and the kindly goddess breaks a goddess-rule to give Inari the ability to change herself back. Now, Inari can change her own shape at will, and using her new skill is very tempting as she keeps trying to win Tanbabashi's heart. But if Inari flaunts her ability, both she and the goddess might end up in trouble with Amaterasu!
