Infinite Mana in the Apocalypse

An Apocalypse descends as awakened humans rise to defend their world! In the blooming chaotic Era, Mana reigns supreme. But even the strongest beings...have limited reserves of Mana. A weak F Rank Hunter awakens with the lowest tier [Fireball] skill in a desolate City as he finds out...Mana is not a limitation for him! Have you seen countless fireballs stretch across the blue skies? Have you seen endless dwarf stars and black holes conjured against insurmountable Dragons and other mythical creatures?! With Infinite Mana, anything is possible! --- "What you are is a blip on a glorious path. An extra that isn't even all that well developed. You'll appear and make some inconsequential waves, and then you'll disappear just as quickly. Only to be forgotten a few pages later."- Noah Osmont, Chapter 2188
