Tree of Aeons - ThreeTree Defense Initiative

In this world, human are in peril. 72 Obelisks suddenly appeared out of nowhere, infecting the world with Monsters. Amongst this chaos, people look for hope.

A man named Basil Pacifer is the humanity's hope. He is the strongest Mage alive at that point. Sadly, he believes in no man, and he always moves alone.

...

Basil observes the unfolding scene bitterly. He is aware of his impending doom, however he has no grudge. He has lived long enough to achieve things people can only dream about.

Looking back to his past, he realized his life is nothing more than a sad story.

Closing his eyes, he accepted his end — or so he thought.

Even though his intentions were not so, he could not avoid the matters of family, country and world.

“There was once a person that stood at the top of the golden pyramid,

with the innumerable cheap jealousy and envy of people,

he walked this road escorted by tens of thousands of people,

yet he could not escape the long and lonely sleep under the gravestone. ”
