Lusus Naturae

[Freak of Nature] When Kirigaya Minetaka and his wife Midori found a strange 'pod' in the mountains, they knew they should have walked away. When a confused and weird-eyed little kid came out, the feeling was only doubled so. But...he seemed harmless, and he made their daughter laugh, so really, bringing him home couldn't hurt, right? After all, what's the worst that could happen?
