@Deppresoexs0erso (Y/N) has Consumption's ability, which is called Digest. It allows Consumption and (Y/N) to temporarily call upon the characteristics and abilities of a devil or part of a devil they've eaten, in exchange for sending that piece (or a portion of it) to hell. With the quantity of the digested material or its amount in comparison to the entire body of the devil (If they digest a bite of a devil, then they'd only digest a small percentage of the entire devil's body, and get a small boost) affecting the strength, potency, and duration of the abilities.
Hi Im currently working on my own manga and im still getting the plot and that stuff down but I was wondering If i could use your Idea of the consumption devil. When i mean this I mean like the whole thing about eating other of its kind and use their power. How this will work In my story Is there are these spirits In our world and they were born from humanities mind. Like lets say a fire spirit, they are the concept of fire and what it represents or even love and there are good spirits who love humanity and thrive from them but there are other spirits who despise humanity and see them as a disease so they kill them. Thats what I got so far If you think I should add or change anything let me know
