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？

Unfazed by Baiyi's chilling threat, she calmly replied, "No, no more Duchess. I left that filthy place long ago. Just call me Harllotte."

She glanced down at the toppled plants and said, "These adorable kids are only asleep, you see. Don't worry; I'm not so bold as to really hurt them." She stepped closer to the Fifth Walker, and the blurry moonlight illuminated her alluring figure.

"Or, rather… are you looking for a good chance to turn me into a dryad, as told in legends?" She cooed, offering up an irresistible suggestion.
