What about Karin: chibi Vampire (the manga, not anime). The parents are a central subject which heavily influences on the condition of the main characters. Despite grudging their daughter's inability to 'clean up' after herself after a bloody incident, they are fiercely protective of their daughter and her share of the family secret. Kenta's parenthood is also a driving force in his life. Kenta and mother ran away due to been ostracised by an in-denial Grandmother. With this experience Keta's mother helps a runaway girl to return to her family after explaining that it is regretable to run away from those who still care about and accept her while there are many who have no choice in being shunned and abandoned by a family. She is constantly worried over the affect their poor financial situation is having on Kenta's teenage developement while Kenta struggles to cope so as to remain with his mother.
