I want to go with the obvious and say Riku because she is a literal fluffball. She is adorable. She'd give nice hugs.
But aside from Riku I'd say my close फ्रेंड्स here are huggable too lel. I'd give each of them a hug if I saw them irl. Actually quite a few people here tbh, even people I don't know too well.. hug me ._.
Once again, I have been caught off guard. To be honest, I'm pretty awkward when it comes to hugs but then again, I don't reject them either XD There are a few Fanpoppers that I find huggable myself. Most notably:
Candylover. BlindBandit. Riku. Zeppie. DisneyPrince. आप (Roxas). Mauserfan. Shadowfan. AquaMarine.
The people mentioned above give me a really squeezable vibe. Their Aura certainly emits huggability to me !!!!
