Thanks for the rep, kisuke. In case you were wondering where the inspiration I got came from, much of it came from Devil May Cry 4, but there were other sources. Some of it was even from anime fan art i found. But I really hope that Kaguro will earn a place in the Hall of Fame.
I'll remove the Absolute moves and replace them with one I came up with today:
(Shikai) Bloody Raven - By channeling reiatsu into the blade, the black aura expands until it resembles a lance, enhancing the sword's physical power and allowing it to burn through flesh. This technique is only active for 10 minutes and has no effect on the other abilities.
(Bankai) Bloody Phoenix - By channeling reiatsu into the blade, the runic charges glow brighter and a bluish-black flame engulfs the blade. Along with the benefits of Bloody Raven, this technique grants access to more powerful techniques. Like Bloody Raven, this technique can only be active for 10 minutes at a time.
What are these new, more powerful moves? You'll have to wait and see sometime later in the week. Two new moves plus a revised Dying Sun.
