Touché, Mus1cLov3r. I'll give you that much!
OK, next up, I'm presenting some characters from one of TDW's early arcs, which I call the Demon Invasion arc. The premise of it involves the demon world known as Makai, which is a similar place to the Afterlife/Pure Land, that it exists separately from the physical world, and it also involves one of the princes from that realm, Gouki, escaping to his mother's home in the Human World because he's learned about his half-brothers attempting a coup d'etat against their father, the King of Makai, Gouken.
So first up is Gouki, the protagonist of this arc. He is the half-human son of Gouken, who, along with his sister Botan, was born to a human woman named Pema about, oh, 200 years prior to the events that led to the formation of the Hidden Leaf Village by Hashirama and Madara. He had lived a peaceful life with his mother, often meeting his father at the same time now and again, until the day Pema was killed. Then, Gouki and Botan went to Makai to live with their father, as well as to accept their roles as royalty. Though he is royalty, Gouki is a down-to-earth person, very kind and compassionate as well as being modest, hence why his clothes look like they'd be worn by a blacksmith or something.
In the early events of the Demon Invasion arc, Gouki learns that his elder half-brothers, Gozen and Goshin, are plotting a coup to topple Gouken due to viewing him as "weak" for wanting to establish peace between the Human World and Makai. Gouki thus escapes from Makai to the real world, winding up in the Hidden Leaf Village.
Gouki's overall story is that besides his being a representative of this whole new world, is that he also struggles with his inner nature, particularly his Yoki or demonic energy, because of the fact his being one of the first half-human half-demons, he has an INCREDIBLE amount of Yoki, which makes him dangerous when it comes out, but he lacks control of it, which is why his horns are cut off and shaved down, as a sign to keep his power in check, and a visual nod to Hellboy. He also will remain part of the Hidden Leaf throughout TDW, helping Tsunade, Shizune, and many others as best he can, and even introducing items from Makai to help his new family.
