Takumi from Fire Emblem: Fates, trained with 3 outfits:

• Default appearance: defTakumi, ponytail, long hair, gloves, armor

• FEH Swimsuit: sumTakumi, ponytail, long hair, barefoot, abs, topless male

• FEH New Year's: newTakumi, ponytail, long hair, japanese clothes, kimono, scarf, sandals, hakama, tabi, wagashi

You'll likely need to lower the weight to around 0.6 to do large outfit changes. Also his hairstyle is pretty baked, without "ponytail" and "long hair" your gens might not resemble Takumi at all, but feel free to try without them and see if you get good results.

Recommended weight: 0.6-0.9
