Lore
Seven years. Seven years of training. Seven years of hatred and strife. Seven years of redemption and happiness. Seven years that were finally over. Ryu had finished his apprenticeship under his shinobi. And now he was recognized as a shinobi himself. His ceremony was in seven minutes. Seven minutes of waiting. Seven minutes of impatience and worry. Seven minutes of excitement. Seven minutes that were finally over. He walked through the town to his shinobi to graduate from simply being a ninja. He knew perfectly well that he deserved this more than his lesser brothers now gazing in awe as he walked down to his master. The shinobi called for silence. Ryu thought to himself of all the great things that lie before him as a shinobi. But as Ryu's master was about to finish the final words someone bursts through the door shouting that a Sengoku had started. A war had begun on my day of becoming a shinobi, thought Ryu outraged that his shinobi couldn't at least finish the ritual before the messenger had come bearing this news. Luckily however, the shinobi continued with the ceremony as if nothing was said. Seven more words were left to say. Now six, now five, now four! Ryu was excited now, only three more words. Two left now for him to officially be a shinobi. One last word. But the shinobi couldn't speak it. Ryu took a step back and saw that his shinobi had been dishonorably stabbed through the back. Ryu could no longer become a shinobi and he knew this well. Furiously he drew his katana and dueled with this murderer. Unknown to Ryu however, he had only seven seconds left to live. Seven more seconds of regret and anger. Seven more seconds of fulfillment and contentment. Seven more seconds that were now over. Yet, he was not dead. How could this be, Ryu thought. He obviously had been impaled and was lying on the ground. His heart obviously no longer pumped and his lungs no longer breathed. Surely he was dead. And yet here he was lying with full consciousness on the ground in this slowly sinking building. Sinking into the ground, no the ground was sinking into the water below. The entire island was falling into the depths and Ryu could not move. As the water flooded the building Ryu saw a light that he held on to. He held on to it and stood back up. He had renewed strength and vengeance to find a kill the one who had taken the right for him to be shinobi away from him.

Hey guys! I know that I haven't made any of these hero idea thingies in a while, so I hope that this super long one makes up for it. :P Anyways, thanks for reading and please comment on what you think about this hero or even a theme for the next hero I'll make. See you guys in the next one! :D

You're going to have to change his ult, Legion Commander already has it.

While it does seem similar to Legion Commander's ult, it makes it so that no one can interfere (allies or enemies), and it allows you and whoever you single out to use spells and items. But thank you for your feedback anyways! I suppose that if enough people want me to I could change it.

EDIT: Oh, and the person you single out (or you) can just run and don't have to attack each other.

OH! you might want to specify that, if you reread that it's pretty vague. When you say "ignores all else" you might want to note that they can use spells and items. And that they can go away, aha.

describe it as that all of the spells that will be used on them will be rendered useless (but buffs and debuffs place before Single Out will not be dispelled)
