>>44023295She's Paraguayan by birth but lived most of her life in Japan.
Her dad married a paraguayan girl, her biological mom, who died. Then she took Hina with him to Japan where he married her current mom. Since her mom wasn't Japanese and she wasn't born in Japan she couldn't get Japanese nationality. She was allowed to stay under an special regiment while she was underage, those documents she tried so hard to get where the Japanese nationality, which she couldn't get. So she was forced to leave the country, hence her recent implications of being forced to leave her house.
She had no option but to go to Paraguay with her biological mom family, her cousins. Her adoptive mom was with her the first weeks but she later went back to Japan, she's now there by herself.
