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？

When they were soaring through the sky, Baiyi's ears were almost deafened by the two loud ear-splitting screams. Even though he had already laboriously cast a layer of shield enveloping the two of them, giving them the freedom to shriek and not swallowing a stomach full of air, the two girls were still strongly overcome with fear and did not dare to open their eyes to look at the scene.

... But somehow, it feels quite nice having these two soft warm bodies hugging me tightly... Baiyi sighed in contentment. As a matter of fact, he kind of wished the feeling would last for a while longer. Without any further hesitation, nor any sense of embarrassment, he cast a Levitation Spell and slowed down the speed of them falling towards the ground. Rubbing the head of the two girls gently, he coaxed, "Have a look!"
