I am Eleu Triya, I live in this world where killing monsters and clearing nests is the most needed job.

When I was a child, I was having some weird delusions. I was always seeing creepy monsters lurking around me, some of them are even following me.

My parents brought me to a doctor to check my condition. I was perfectly fine, my brain isn't damaged or traumatized of these monsters like what my doctor is concluding.

I've never seen a monster at that time. My father decided to teach me some self defense so I won't be scared of monsters anymore.

Few years after, that I've stopped seeing those monsters. My father have taught me some sort of things that cause my desire of fighting has even grown more. That time I've decided to become a mercenary so the things that my father have taught me won't be in vain.

It took some time for me to completely forget those fearful experience. I've totally forgotten how they look like, how they move but there's one monster that I can't erase in my memories.

A monster with a humanoid body, it has no eyes and the left side of its mouth is torn that is always showing its countless teeth. It's the most creepy monster I have seen in my delusions. It is always circling around me and never leaves me wherever I go.

That monster also disappeared the same time those other monster vanished, but that monster is the only one that never leaves my memories. I've became strong willed and a delightful child after moving on from that experience.

It is until I've become a mercenary, days have become hellish and my personality have completely changed to how I was back then..
