Now this smol bean!

Who I Frankenstein-ed into a demon!

Here's Ken!

As a Demon Slayer, his Breathing Style would be Stone Breathing, though he would mostly use Third Form: Stone Skin to better accommodate his sword.

As a demon, his Blood Demon Art would be Metal Tomb. The plates he grows on his chest and arms can sprout tendrils of metal that he can either maul or shoot and completely entangle his opponent with, slowly crushing them to death. The plates can also extend around his limbs to create an impenetrable armor. The tendrils also come in handy in picking up far-off objects - and people.

What do you think?

And who's next? I still have demon blood to spare!
