In the Expansion Main Story..

[Kayokane]

Let's see...
I'm a Second Lieutenant in the Maelstrom.
I've felled Ifrit, Titan, Garuda, Leviathan, and Ramuh.
I've killed 2 Imperial Legatus (Legacy Character).
I've destroyed Ultima Weapon.
I've bested an Ascian.
I've fought pirates, giants, cultists, voidsent, dragons, marmots, bombs, hell even treasure chests!

but most importantly, I look out for the little people no matter that task I'm given.
I'm merely an adventurer.
Some may call me Hero, Defender of Eorzea, Warrior of Light, or Eikon Slayer, but I remember my roots.
Still green entering the Drowning Wench for the first time with a ballonfish in my pocket.
No task is beneath me, save killing an innocent. That is our true glory.
Anyone can fling about my name, but only I can prove it's worth and thus do I declare: Let There Be Filler!
