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？

For the rest of their time, Baiyi graced his coworkers with the story of the fascinating adventure that he had just had.

They sat in a cafeteria, and each of them had a cup of coffee in hand even though neither of them could actually drink it.

It started out as a way to avoid the coffee going to waste, but later it became a great story-telling technique as Baiyi made the coffee soar out of the mug and morph it into different characters and objects of his story. He told the story in a theatrical method, while the characters made from coffee animated the words he said to reenact the story.

Baiyi told two riveting stories. The coworkers were fully immersed in them.
