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？

Baal knew that the Voidwalkers had escaped death.

"Humans are a joke. Has nature failed to teach them that the sky is more treacherous than the earth?" Baal smirked. "Come to me, lightning and thunder. Tear these fools apart."

Almost immediately, the dark clouds above released arcs of gold lightning. The sudden expulsion disturbed the air, quickly forming gales.

"Damn! They sure are heartless!" The Archmage was alarmed. He quickly issued an order to the city guards: "Quickly, the barrier!"

A magic barrier appeared over Arfin City, and only moments later, the arcs of golden lightning struck the barrier hard, resulting in a blinding white explosion.

When the lightning dissipated, the magic barrier — despite being a powerful Forbidden Spell — was riddled with cracks.

"If the barrier is struck by that thing three more times, it is finished! Everyone, put your all into maintaining it!" The Archmage yelled.
