roboko_(doraemon)
A character from Doraemon. She is a "Rental Friend Robot" that ]] brought from the future to comfort Nobi Nobita.
While she seems friendly at the first glance, she is very obsessive of Nobita (arguably borderlining [[yandere) to the point that Doraemon was forced to sent her back after she attack Nobita's mom for "stealing" him from her.
