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>As today was the first day of school for the newly admitted students, Baiyi did not conduct any proper lessons; instead, he replaced it with an overview of the previous classes that had already been conducted. He then prompted the students to consider what they would like to learn, and he asked Tisdale, the appointed class head, to gather everybody's opinion. Baiyi could only choose to only teach certain subjects, for his time was limited.</p>

<p>Having made that arrangement, Baiyi gave the students some time to themselves while he prepared to ponder some student-related matters. However, as he prepared to leave, he suddenly heard a melodious hum coming from the corner where the potted sunflower was.</p>

The New Students Were Not Simple At All
