Trained on animefull. Contains both his default outfit and an okay representation of his FEH Ninja outfit.
Default appearance: defShinon, ponytail, cape, armor, fingerless gloves, boots
Ninja FEH outfit: ninShinon, ponytail, scarf, japanese armor, headband, sandals

Will likely need to increase the weight on headband to "(headband:1.1)" or higher for it to appear, and even then it's not very accurate
Weight 0.6-0.8, 0.7 is a good starting point.
