Depends, does the enemy have a ninja that dodges nin damage? If so, yagura's chase would get dodged and that would terminate the combo (whereas tenten mystery is tai+nin, so it won't be dodged)
Also, is the combo really set to 0 or did it just stop? Because death could terminate the combo w/o resetting the counter.
Really need more info on your enemy to know what happened.
