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>Just as Baiyi was having a great time spamming forbidden spells, which made him feel a high that only the Sorcerer Class could provide, Godsfall's day was coming apart at the seams. If the Wise Mad King lived on earth, it was at this point he would be getting a consistent stream of beeps from an alarm system, saying, "Nuclear Launch Detected! Nuclear Launch Detected! Nuclear Launch Detected!".</p>

<p>However, he and Godsfall were quick to react. After Baiyi's first spell, they took action. Despite calibrating the coordinates of the second location three times, Baiyi still failed to hit the target. Godsfall quickly cast a large defensive barrier over that location.</p>
