Wow that's one surprised, and very cute I might add, Reimu there. It is almost saying 'sweet sweets go here' with it's eyes as well. A nicely done sketch too, worthy of praise.
Being an animal lover, even if this thing DID come into my home unannounced, if it did it with that face, and without shitty demands, I'd give it some food, a few paper towels to sleep on, and gently see it out the door.
