1) Is Citro really Villager's blood brother?
To be honest, they really do look similar, Citro, Villager and Tachibana.
2) If yes, do they share the same mother? I mean, tbh Villager's body accepted Mao's blood too easily, it must mean something, right?
3) What is Citro's age? Is he younger or older than Villager? Was he born before or after Tachibana's gone missing?
4) Why the heck are the kids named Villager and Citro, but Tachibana is Tachibana???
