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>A war broke out, but this was not the surprising part. Contrary to expectations, this was not a battle for dominance between technology and magic; it was a battle started by a techy mecha-geek and a techy paramilitary-bro.</p>

<p>The Blacksmith Walker and the Engineer Walker — the only futurists among the Voidwalkers — paired up for most operations, but they had their differences. For one, the Engineer Walker was a Gentleman of the Void, but the Blacksmith Walker did not share this taste. Both Voidwalkers also had different views on what constituted the pinnacle of technology. This simulation had presented the perfect opportunity to decide if enormous 'ultimate weapons' were better than regular paramilitary tools. </p>

This is Where We Part Ways
