I need some help to find an specific manga

Hi everyone! Is anyone able to help me? I just remembered one time I was reading a manga about people who had tattoos of a specific animal/spirit they could summon whenever they wanted to fight. I do remember the main character had one of a tiger on his back that looked pretty cool until he summoned it and it would look like a human in a bad custome, and there was a girl who had two wolves, one on each leg, and those were amazing. Does it ring any bells? I never finished it and I can't recall the name, I've been looking for it with no success.
