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？

"Godfather? If the house is such a big deal for everyone, well…" Vidomina wrapped her arms around Baiyi's neck as she continued.

Her invitation sounded forced, most likely because she was reluctant to visit any places her father, Duke Wright, had bought for her. It was very likely that she had never visited the place before herself.

"Nah, it's fine. Let's just walk outside," Baiyi replied, and he reached for her head to give her a comforting pat.

Suddenly, as if a wild thought had crossed her mind, Little Mia jumped right into the scene, and she pulled Vidomina into a forceful embrace and asked pointedly, "Vidomina, why are you hugging Mr. Hope like that?"
