Let get 3 characters Edel, Veigas and Uno
While Yuan and Akuji were created fews days after Ethan, there some noticeable indirect in my comic before the creation of all 3 GC char.
Edel's rapier, I had that idea weapon from Sieghart, but wanted 1-handed in Yuan's 2nd job but since I haven't gone through as the story is still slow, I had changed to another different type rapier.
Veigas, well I wasn't expecting another char, again, both Yuan and Veigas have gold eyes, however, Veigas has more the goldenrod colour while Yuan is bright golden yellow revealed to be a coloured contact. Then we have the killing part, but since Akuji's priories are different, and Ebony was introduce later.
Uno, now when I look at Uno, his chibi form, I keep thinking he's the reincarnation of Ulquiorra from Bleach, try compare the face don't tell me it doesn't look like him, and the way his design is similar to Ichigo's Bankai, I even watch as he held his weapon also like Ichigo in relax stance.
Now Ebony has the same design cut in torso form, but it was to cover up the bust design after Akuji's, and you know girls aren't allowed to show so much skin just because it too revealing. Well excuse us for revealing, if you boys can show your full view chest.
Uno is pale and need blood for his thirst, and all you know that Ebony is dead, so the natural pale for undead, but the blood I drawn was from Ronan's dream before Uno is created. Hmm now that I look at his hair colour, it almost the exact black colour as Yuan's hair and if he has in bandage covered up...
Now while I only got 1 idea indirectly stolen, the rest is similar, you think KOG is reading your mind.
