Sup guys I know I didn't get to talk much last time but I want to thank everyone for their support and I want you to know that the next chapter I'm gonna write it and it's just gonna be like "If you don't want your teigu here anymore tell me and I shall get rid of it for you" and stuff like that.
The Crimson Reaper: Darkin (I wonder who'll get the reference)
Design: When in it's dormant, it takes the form of a black gauntlet with red vein like stripes over it. When activated a black sword(it can be a different weapon depending on the user) materializes from the gauntlet. The sword is has 3 sides as opposed to the classic 2 sides, and each side has a serrated pattern with 3 blades that points towards the hilt and also a bigger blade in the front that connects to all sides (total of 10 blades). The center of the sword glows blood red and it's hilt is 3 blades that looks like the head of a 1 handed axe and unlike other blades they point away from the hilt.
1st ability(Passive) Ever Growing Bloodlust: With every passing second the user is in combat, they become faster and if the users takes damage it also triggers this too.
2nd ability(Passive): Everytime the user lands a strike on the enemy and spills their blood the sword absorbs the blood/life energies of the opponents, slowly restoring the stamina of the user and heals their wounds.
3rd ability: The user can enhance their attacks to the point every blow can break through enemies defensive stances and techniques. But using this ability also slowly drains the users life force, leaving them exhausted and making their wounds heal even slower. (Not a permanent drain. But needs time to restore it.)
4th ability(Trump Card) Carnage: While in battle, after activation the Teigu consumes large amounts of blood that can either be the blood of the enemies or the user's own blood, the segments(bladed parts) disconnect from each other, allowing the sword to extend, thus giving larger range of attack and increases the users agility and heighten their senses and their attacks becomes more brutal as well. Also glowing red markings appear over their arms all the way to their neck and their eyes changes color to Black center with red surrounding it.
Compatibility: This teigu doesn't need much to wield other than the user has to be a proficient fighter and doesn't afraid of spilling blood or killing their enemies. Also in inexperienced hands the 1st ability and it's Trump card can drive a person mad and consume them in their own bloodthirst, thus turning them into mindless berserkers.
Origins: Lost in history. But there are theories that rather than from a beast this teigu was made out of the body of a serial killer in the early years of the empire and that this was his punishment.
So yeah next chapter is just gonna be some info and then when people submit I'll post those, BTW this is the early stages of the story so if you submit right now you have a 95% chance of getting a chapter in the next 5 at the very least.
