Rinrin

Gifted in the fields of science and technology, Rinrin spends a lot of her time building things but constantly asks her brother for monetary donations to keep her projects going. Lately, she's been constructing a robot duplicate of herself, Mecha-Rinrin (メカ鈴凛). She speaks with a strong Chinese accent and addresses her brother as Aniki (アニキ), another way for a boy to address his brother. In English, she calls him "Bro".
