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>The Second High Reverend of Godsfall cult felt very confident, as though Baiyi's life was already in his hands.</p>

<p>Even his counterparts, the First and Third High Reverends, were surprised at the amount of optimism he had. However, the Third High Reverend soon became skeptical. "You are saying that destruction is the only fate that awaits him as though you have forgotten that he is the messenger of the ever-so-cryptic War God! He enjoys all the War God's privileges, remember? This same Hope forcefully pilfered a very powerful object that is rumored to be the legendary Book of Servitude. Against a foe like him, numbers are meaningless; regardless of how capable your fairies are, they are still leaps and bounds beneath the best the Church and the Northern Lands has to offer."</p>
