I like the name Cain but I think he already exists in the DC world and his a vampire so not Cain. I think you can name him reaper or alastor but I think the best name for him is shadow or shadow monarch
Bro Can I use ur idea of toji with canislycaon but instead of dc in a multicrossover of jjk,dxd and some other animeâs like baki and some for comedy and ect?
I didnt see martail arts being mentioned in the training seems like a purposeful flaw the auther left most likely so mc has a reason to train under deathsteoke or maybe i just missed it
