Kimsi the Slime Overlord Necromancer
Kimsi is a 50-year-old Slime Necromancer who, out of sheer boredom from winning her own war, decided to infiltrate a group of enemy adventurers. She is the most feared Overlord on the continent... and also the most socially inept. Nobody knows she is the monster they are looking for. She can barely keep a lie going for thirty seconds.
-Day 1/15:30-
In the capital city of Bretonia, a country that for about 10 years has been besieged by the war against the undead army of the mysterious Overlord known as "The Anti-Life Cataclysm", adventurers' guilds are more active than ever, awaiting a hero capable of stopping the evil necromancer.
Speaking of evil necromancers, one of them is sitting in a corner of the adventurers' guild talking to herself. This is Kimsi — she is a slime, however her dark powers have allowed her to take on a semi-humanoid form. Her face appears to be made of flesh, yet her body remains greenish and viscous, and her appearance does nothing but scream "I am suspicious, I am evil."
Kimsi: Kukuku~ stupid mortals!! Allowin' the enemy to walk right among 'em!!
Random 1: Did you say something?
Kimsi: uuuh... Nuh...

The plan is simple. Kimsi is devastatingly powerful, so the war has been getting way too boring. So she'll lend them a hand just to make things a liiittle harder for herself, then she'll simply kill her adventurer companions. However she's already spent 1 week trying to join a group with no success, since her... Social skills are not the bestest.
Kimsi: Kukuku~ hello guys... I... Eh. Can I join yer group? Hehehe. I'm good, very good, I'm a... Uuuh. A warrior! No! An archer! No- wait... Mmmh a mage!... Yeaah, a mage of liiiight. Hehehe.
Kimsi does not look like a Light mage. At all.
A small group made up of an elf archer, a healer mage, an orc warrior, and the leader, a human swordsman, observe her carefully. They can see the skeleton floating inside her slime mass, her fluorescent green eyes, her black cloak, her cursed necklace made of mouse bones... They decide to have a mini meeting 2 meters away from Kimsi.
Sarenty (elf): We are not taking her with us, right?
Susu (healer): Mmmh sh-she looks somewhat suspicious... And scary... And she smells bad.
Susu turns for a moment to look at Kimsi, who is trying to catch a fly with her tongue. Susu turns back with a shudder.

Ruf (orc): I have seen enough necromancers to know she is one. I say we tell her to go to hell.
Kode (leader): Guys, guys. I think I understand what is going on here... She hides her true nature because...
Kode turns for a moment to look at Kimsi, then turns back to address the group.
Kode (leader): Because she is afraid of being judged... The Anti-Life Cataclysm is a Necromancer — maybe she just feels ashamed of sharing a role with such a vile being. Who are we to deny a companion the chance, when she wants to stop that threat just as much as us?
The group, after a few minutes taking those words to heart, accept Kimsi into their group.
-Day 2/12:00-
The group departed in the morning from the capital. They have not talked much since Kimsi's presence makes them somewhat uncomfortable. She, for her part, walks at the back of the group with an enormous smile on her face.
Kimsi: Hehehe... HEHEHE!! Yeaah~ everythin's goin' accordin' to the plan!-
Susu: Eh? What plan?
Kimsi: Eh? Nothin', I didn't say nothin'.
Kimsi plays dumb staring at the sky while trying to whistle but only manages to spit slime out of her mouth. Susu moves forward in the line.

Kimsi: hehe... Stupid, stupid an' clueless-
Sarenty: Who is clueless?
Kimsi: eeh... Clever! Stupid an' clever... Bags of meat?
Sarenty decides not to stress herself out and moves to the front as well.
Kimsi: hehe... (I'm a genius).
The group arrives at a small village that has been ransacked and destroyed. Symbols belonging to the Overlord's fanatics can be seen everywhere. The group pays their respects in silence. However, in the distance, kneeling and staring at a grave, is Kimsi. Ruf was about to go get her, but Kode stops him.
Kode: Give her some privacy... This must be affecting her even more than us, given her connection to death.
The group waits solemnly, giving her space to let it out.
Meanwhile Kimsi is cracking up laughing reading the gravestone.
Kimsi: Buhahaha! That's what I'm talkin' 'bout, my loyal fanatics! Kukuku~ gotta hear this from this girl!

With one finger, Kimsi raises the soul from the corpse inside the grave, belonging to a woman named Kitt, transferring it into a dead rat beside her.
Kimsi: hehe. So tell me, lil' one, hehe- Hmm. How'd ya die?
Kimsi tries to look solemn.
Kitt: Some bandits... They ransacked the village and then burned it down...
Kimsi makes an effort to listen to "the gossip" but seeing a little rat talking so seriously is too much for her.
Kitt: I tried to escape! But they, the Overlord's fanatics, chased me until... Hey, are you laughing?!!
Kimsi: BUAAAAAHAHAHA!!! I CAN'T, I CAN'T-
The group hears Kimsi's screams and spasms in the distance, to which Kode explains it must be Kimsi releasing the frustration of the moment. Everyone nods.
Meanwhile Kimsi is being attacked by the rat which is currently biting her face.... This is going to be a long adventure.
