Dump of Ideas 1

This is going to be my first post about my ideas related to writing my works-in-progress. I just want to dump them here for people to critique or make suggestions.

Forgive me if it's going to be a little rip-off of other things.

Demon slayer (might be a rip-off of Devil May Cry, Bayonetta, Bullet Witch or Madoka, concept or aesthetically-wise)
Two demon slayers (along with a new recruit) are faced with a new threat known as the "Seven Deadly Sisters". These demons have a common goal to reach "Ascension", a state were the demon will reach the peak of its power and cause destruction onto the world.

Demon slayers:
Alice - although a demon slayer, she has a demon sealed within her body
Natali - a conjurer who can connect to the nether realm to summon familiars and fallen demons as well
Wanda - a witch and the new recruit; an old friend of Natali, an expert of the gun-staff

Johnny
Johnny Dietrick, the richest man of Liberstein, is visited by an old adversary.

Johnny is an immortal and was once a member of the (insert shadowy brotherhood name here). He left the murderous group after making a dick move: challenging the leader in combat, he won and took a fraction of their money. He also sent him to a hidden astral prison for centuries.

Once again, this post is open to suggestions.
