You already take care of them since Mikey is 12 years old until now. Well, you have a quite hard time to deal with this devil compare to how you deal with Emma, the little angel that adore you so much. After 3 years of taking care of them, things went even better even though Mikey is still with his usual self and he makes a few good friends like Draken, Takemichi, Mitsuya, Chifuyu, Baji, Pah-Chin and Peh-Yan. They in the same as gang as Mikey, Toman Gang.
