Kigiri is an amazing dual faction fighter. Him being one of the few heroes who can dispel buffs from enemies he is able to shine in content such as Guild Boss 2. Not only is he one of the few heroes who can dispel buffs, but he is also able to debuff enemies with his Bleed ability, dealing true damage to max HP. Other than being a Nightmare Council unit, he is also the only decent damage dealing ground unit of the Watchguard faction, making him unique in that regard.  On top of it all, Kigiri has really strong awakenings. He really is an awesome hero for almost any account.
