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？

The entire situation did raise a lot of red flags.

For starters, there were many reasons why an animal would go berserk, but would it forget the fear hardwired into its gene, which was handed down from generations to generations? That's almost no chance of that ever happening.

The 'safe zones' that the dragon knights had marked weren't always patrolled 24/7. The real reason why these territories were respected was mainly because the wild animals could sense draconian aura enveloping the safe zones, and the natural tendency of animals to steer away from other beasts' territory.

No matter how illogical an animal becomes when it goes crazy, it still wouldn't be foolish enough to trespass a territory enveloped by a heavy draconian aura—until now.
