Tengu and Sun Empire Wandering Samurai are mercenary ronin for Ninja All-Stars. Ronin bring potent new abilities to a player's team that are entirely unique to them. As mercenaries, ronin may be used by any player, on any team.

For centuries, the Tengu have bartered or traded their magical and martial skill to the competing clans of Kagejima, sometimes for gold, sometimes for unusual and esoteric items like the whispers of a loved one.
