As expected, some of the darker stuff is now starting to seep through the cracks. Akari is getting bullied and Shizuku is getting ostracized. And they both appear to be abandoned children with no parents around. Could be orphans with no relatives, or just simply abandoned by irresponsible parents.
And then a beautiful man with similar-colored hair and eyes came for 102 (I keep having to remind myself that 0 is not a woman...). So according to him both of them are artificial humans who escaped (from some secret laboratory?). At least he's not a killer on the loose who'll hurt the girls. Right?
He's asking them for help, but I wonder what could two poor little girls with no parents exactly do to help? They can barely survive by themselves until 102 came along...
