By the time Xin Hai was fourteen, she had turned into a cruel and selfish ruler, causing most citizens of the island to fear and hate her.
One day, she had a sudden urge to bomb Belarus, so she did, wiping out 99% of its population. This caused Russia to become enraged (overjoyed), so he donned a red armor with very obvious breast plates and boarded a ferry to the island. For some reason, the ferry needed a month to reach there.
During that time, Xin Hai ate a lot of brioche (and became fat), and "fell in love" with Japan. Because of this, she tried stalking Japan, but failed, as the only hiding place in his house, the closet, was too small for her to fit in. While she was trying to fit into his closet, she discovered many erotic mangas. Because Xin Hai is a very naïve girl, she stole all the mangas and started studying them.
As if Japan didn't notice.
