Genya Shinazugawa is brother to the Wind Pillar. Demon Slayer manga. He eats demon parts to temporarily take on demonic traits such as quick regeneration and some blood arts. SO... any ideas? I already gave him a sword and his sawed-off. A couple pints of demon blood to get him started.... Genya Shinazugawa

Just some samples of types of items: Stuff to fight demons:

Demon parts to eat:

Demonic minions:

Summoning/controlling stuff:

Aww, thanks! I had totally forgotten about this!
