This is my first time writing a fanfiction so any criticism is welcome. Besides mainly taking inspiration from Monster Girl Encyclopedia where the setting of the story is, I also took inspiration from other media such as Warhammer, Berserk as well as DanMachi which give the story a more fantasy aesthetic rather than the traditional smut MGE story. I hope you have fun reading this.

The story of General Arthur Bell in a world of Monster Girls.

Part 1

My name is Arthur Bell and I am the General and leader of an expedition that will head to Darkwood Forest in order to purge the monsters that have infested that area, with the help of new technology that will turn the tide of this centuries old war. We are currently in Lescatie from where the expedition will start and I find myself talking to Lady Dascaros who is the commander of the unit assigned to protect the castle of the city. While talking to her I noticed her gaze often dropping on a particular soldier who also seemed to attract gazes from other prominent ladies, though he didn't seem to notice it.

-Lady Dascaros, someone seems to be stealing your attention from our talk.

-I don't know what you mean Arthur, but I…I have to go.

So she abruptly ended our conversation about the security of our supplies and left, which made me chuckle.

Afterwards I approached that soldier and that was when I met Elt. Eltwas a soldier in the army for a long time and had met and befriended in that time a lot of girls, which he didn't know had developed an interest even if it seemed obvious. After I made him aware of the gazes he was attracting, he blushed and excused yourself which again brought me a chuckle like the previous one. With the preparations complete and with the blessing of the King and the Cardian of Lescatie, we embarked on our crusade under the protection of the Chief God, bringing with us a box whose content wouldn't be revealed yet.

After days of marching we made it deep into Darkwood Forest. So far we strangely hadn't encountered any monsters so we made camp and I decided that it was time to test our new weapon, the 'Musket', by using it on what was inside the box. As the curious soldiers of the expedition watched me open it, a lot of them suddenly got scared but also intrigued once they found out that inside of it was a monster called a Succubus, since it was the first time they had even seen a monster. Most of them were surprised by how beautiful it looked, but they didn't realize how dangerous it really was like I did. So they were even more surprised when I announced to them that this beast was going to be executed with our new weapon. When I gave the order for the firing squad to prepare their muskets she suddenly spoke:

-Arthur? Arthur! It's me, Mary, we have been friends since we were children. We had so many good memories. Why are you doing this? Even though I look different you know I'm still the same Mary, and you know how much I love you. Fufu…

-SILENCE BEAST!

I said as I grabbed her chains and threw her out of the box.

-YOU ARE NOT THE MARY I KNEW! THE MARY I KNEW DIED THE DAY WHEN SHE WAS TURNED INTO THIS MONSTER! YOU MAY LOOK AND SOUND SIMILAR TO HER, BUT YOU ARE JUST AN IMPOSTOR WHO HAS TRAPPED MARY'S SOUL. It is now my duty to free it so that it can finally rest in the hall of the Chief God.

-Arthur listen to your heart, you know it's not true. I'm the same Mary who has always loved you even if my body has changed. So please, release me, and then we can leave this place and go somewhere remote where we can build a family and make all the hot love we want for the rest of our lives, just the two of us.

At that moment my heart yearned to be with her, to accept her offer, to have children and be both happy, but deep down I knew that even if it was the same Mary, I couldn't accept that offer, since duty towards the nation, towards humanity, towards the Goddess always came first. Yet after the fighting squad was ready I couldn't bring myself to say the orders, because of the realization that all of those years we spent together made me love her romantically as well. Lieutenant James Tragost stepped and up at that moment and took charge, telling the firing squad the three most haunting words that I had ever heard in my life up until that point:

-Ready!

-Aim!

-FIRE!

And her body dropped instantly. Lieutenant James then ordered:

-Dispose of her.

But in a moment of clarity from my shock I said:

-Discard that order and bury her properly, even if she was a monster, she was still my friend.

Later that night I prayed for her soul, but I couldn't sleep because of all the nightmares that I had from that event, which would continue to haunt me as the days passed. After a few days of training with the new weapons and cutting down the trees of the forest so that it can be properly purged (even if we hadn't encountered any monsters), right as I was writing a letter to my mother Catherine explaining what had happened so far, James informed me of a man running from afar towards the camp. I told the guards to stay alert just in case something happened and when the man arrived visible panting, he claimed he was a messenger bringing urgent news and asked to see me.
