As humans we live in a world where insect world is too small and insignificant to grab the attention of most of us.

But what if there is a world where there are no humans. A world where magical beings reign supreme, and intelligent monsters are the kings of their own kingdoms.

Where the phenomenon of mana has embedded so deep into everyone's life's that there are no beings left untouched by its powers. What kind of effect will this magical fuel have on the insects which on our Earth are considered important but nothing more than pests.

Will they gain intelligence to move according to their wills? Will they have thoughts and emotions to convey their thoughts? Can they talk and communicate with other species and live together in harmony or they fight the territorial war like we humans do?

Are they greedy for power, status and position or they are just simple organisms without much complexity and live by the days?

And what if a human soul with no memories, but the intricacies of his human life etched onto the core of his soul, gets to reincarnate into such world as an ant? Will he survive and become another emperor or will he die trying to live according to his ways of the past?

Monsteralia is one such world.
