Sixteenth Basket of Mantaos

Imagine being forced to live, after death, as incorporeal bodies trapped in a vast space of nothingness for thousands of years, with nothing to do but exchanging past memories with other cohabitants (read: weirdos).  Everybody wanted out, but there was no way to leave the Void... 
Until one day, a young man was finally summoned, as a powerful but reluctant mentor, by a bubbly and motivated but completely naive young girl. Baiyi, finally out of the Void, was the only one who could save all of the other 32 souls from their prison and his summoner might just be The Key to their freedom.
However, Baiyi had to use the techniques and abilities the other souls had taught him throughout the years, and together with his own extensive knowledge of anime and game tropes from his shady and dangerous past as an otaku, to face the biggest challenge of them all: training the clumsy young girl he was forced to partner up with… into a competent sorcerer!

Why Did You Summon Me？

<p>Early the next morning, the greatest Demigod sorcerer in the Fairy Kingdom was summoned to the palace.</p>

<p>Roy Dryadspeak — more famously known as Morningstar Sage — hailed from an ancient family; this family co-founded the Kingdom alongside the First Fairy King. As such, the family's name commanded respect from all and sundry. This Demigod Sorcerer, however, had more to him than met the eye. He was the most capable enfant terrible the Dryadspeak bloodline had spawned in thousands of years. He mastered the sorcery of humans at a very young age and became a Demigod three hundred years ago. His existence had flipped the stereotype that fairies could not learn magic on its head.</p>
