One Day, Another Day
Set before the end of the series, it's basically a side story of a day in the Dragon Castle, kind of in Zoma's perspective.

This actually has three little side stories in it. The first one is about Rune's dream about everyone dressed in drag, the second is about a little adventure that the three dragons go on, and then the third is like a day in the life of Alfeegi, Ri-ma, and Duma.

Crescendo
Backstory about how Lykouleon and Kaistern met and how Kaistern then became the Blue Dragon Officer.

From DrMaster:
After his mother's death, Kuro Takagi transfers to Yotsuji Private High School where his father is the proprietor. But Yotsuji is no ordinary school. It holds a strange rule of “No students on campus after dark!” On his first day of attendance, Kuro and his classmates inadvertently break the school’s highest protocol and find themselves victims of a faculty zombie attack. Although they manage to narrowly escape, this is but a prelude to more encounters with the undead, especially after Kuro discover his own blood-ties and latent zombie abilities. From there, it's full steam ahead as this dark and intense action/comedy shifts into high gear.

Once upon a time there was a king who ruled by fear. Upon discovering the existence of the Goddess of Destruction he resurrected her, but this only lead to the destruction of his own country. As a result of the carnage, she was sealed in a box that was kept in a very deep, dark place. The box was locked with many keys, keys that were then spread across the world. Many years later a Samurai discovered the box and decided to challenge the Goddess of Destruction, but first he had to gather all the keys and fight through hordes of undead soldiers. Can you really defeat a Goddess?

Juju doesn’t remember anything – not even his name (it was the writing on his coffin) – and yes, he’s already dead. But he’s been revived and introduced to Liila – a girl with prehensile hair and his right hand has been replaced, so there must be an adventure ahead!
