Senko the main character of The Helpful Fox Senko-san. She is an 800 year old kitsune sent from the spirit world to relieve Kuroto from his overworked and stressful life. She proudly goes above and beyond for Kuroto such as pampering him, cooking and cleaning his home. She moves in Kuroto's home and acts like a helpful wife and mother.
She loves to pamper him such as cleaning him, massage, groom and gives him lap pillows to ensure he gets enough sleep. She gets sad if Kuroto prioritizes work over his health. To her dismay, Kuroto seems to have a fixation on her soft fluffy tail and ears.
