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？

A gust of wind blew past Laeticia's face, and moments after that, silence reigned. She looked up, and her gaze locked with that of the angel that had just arrived in front of her.

Like other angels, this angel emitted a holy aura with a blinding glow. His armor was as impeccable as his physique.

Kimaris looked down and studied the girl before him through his blindfold. "You are the last of the Lord's purest believers."

"Yes. I'm Laeticia," Laeticia replied, getting back to her feet. She did not take her eyes of the angel, though, as doing so was against the teaching indoctrinated into her.

Laeticia was clad in her snow-white Saintess armor, and her golden braids were disheveled today. Her hair fluttered in the gentle breeze caused by the beating of Kimaris's wings, making her defiant. It was as though Laeticia and Kimaris were beings of equal standing.
