Alright, so... I loved the post, harine, but... no. A few things:

It's specifically mentioned that young/weaker Grimm are much more reckless than their older/more experienced brethren. Roaring at them isn't going to make them run away. You're just projecting your emotions even louder, and your character reeks of desperation and hate... both delicious emotions.

Adrenaline is a wonderful thing, but your character has literally been [i]leaping through trees[/i] this whole time. That's not a thing that humans do, and it's not something that a tiger Faunus does. Not to mention he lugs around the extra weight of his mask and his huge claws with their long, heavy chains. To then have the strength and perseverance to do all that fighting is too much. The Grimm would see that he was tired and pour it on.

You suffer from the [url=http://tvtropes.org/pmwiki/pmwiki.php/Main/ConservationOfNinjutsu]Law of Inverse Ninjitsu trope[/url]. While you fight four enemies who conveniently attack in turn, all the other monsters leave you alone for... some reason. Because you yelled at them? I would understand if your character took on a Beowulf, and then another one, and then a Boartusk, and then a minor Ursa and managed to survive, but four at the same time while he's in a swath of them where "There were too many of them, with no end in sight?" No.

I would suggest a collaboration post with Zombehs. Keep the tiger roar; it should do nothing to the Grimm, but it can be a good method to call other groups to come assist you for the "boss battle." I do have to veto the post you have up now, though.

Zombeh, please do not respond to his post until things get fixed up.
