To get the 'Ugly Fellow' trophy you need to equip a Hyottoko Mask and kill an enemy with it. The list below shows you three ways that you can obtain the mask. When you have the mask equip it in a shortcut slot, then befoere you use it weaken an enemy so they will die in one hit. The Hyottoko Mask will breath fire in a two meter radius so you will need to get close to the enemy to use it to kill them. Note: If the enemy does not die you will need to obtain another mask.

During 'The Conspirators' mission (Chugoku region), get it from a corpse in the cave before the end room with the two ninjas. It also respawns when replaying the mission.

Successfully complete the 'Wreathed In Flame' mission (Kyushu region) to get it as a reward. You can also replay it as many times as desired to earn more masks.

Buy it for 220 glory from the hidden teahouse. The teahouse unlocks approximately halfway through the campaign.
