Sakurako has quite the collection of reconstructed animal bones, but she wishes she had more of the human variety, much to the chagrin of those around her. Soon, Shoutarou begins accompanying the eccentric osteologist on the many different unsolved cases she comes across—usually in the form of decomposing bodies. But with so many incidents happening around them, could there be a larger mystery at work in their lives? Sakurako-san no Ashimoto ni wa Shitai ga Umatteiru is a story of two unlikely partners, each showing in their own way that bones can tell how one died, but only people can tell how they lived.

Yuu Koito has always been entranced with romantic shoujo manga and the lyrics of love songs. She patiently waits for the wings of love to sprout and send her heart aflutter on the day that she finally receives a confession. Yet, when her classmate from junior high declares his love for her during their graduation, she feels unexpectedly hollow.

Now, having enrolled in high school, Yuu, disconcerted and dispirited, is still ruminating over how to respond to her suitor.

Stirred by Touko's elegant manner, Yuu approaches her for advice, only to be bewildered when the president confesses to her! Yuu quickly finds herself in the palm of Touko's hand, and unknowingly sets herself on a path to find the emotion which has long eluded her.

The discovery of a hypergate on the Moon once allowed the human race to teleport to Mars. Those who chose to settle there unearthed a technology far more advanced than that of their home planet, which they named "Aldnoah." This discovery led to the founding of the Vers Empire of Mars and a declaration of war against the "Terrans," those who stayed behind on Earth. However, a battle on the moon—later called "Heaven's Fall"—caused the hypergate to explode, destroying the moon and leading the two planets to establish an uneasy ceasefire. Their peace was a fragile one, however. Fifteen years later, high school student Inaho Kaizuka witnesses the plotted assassination of the Vers Empire's Princess Asseylum Vers Allusia, who had come to Earth in hopes of repairing the relationship between the empire and its homeland. The ceasefire is shattered, and the Martians declare war on the Terrans once again. In the face of this insurmountable enemy, Inaho and his friends must now fight against the Vers Empire to settle the war once and for all.
