Haruka Hikari (Mrs. Hikari) Haruka Hikari is Netto's mother, and is married to the scientiest Yuuichiro Hikari. Haruka mainly stays home to take care of Netto, and doesn't seem to have a job. Since her husband is constantly away from home on expeditions, she sees Netto as her main priority in life.

Haruka is so very pretty, and so sweet too!
