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>Although the Engineer Walker's new toy was only a robot imbued with weird lines, it was the marionette he had shown off to the wealthy some time ago, to earn their investment. Back then, Baiyi considered the Phoenix marionette more of a crowd-pleaser than an actual weapon. The huge sum of money that the Engineer Walker raised, allowed him to make massive upgrades to the Phoenix marionette. He increased the machine's power consumption, giving it a greater appetite for Baiyi's Void Energy.</p>
