Hari represents herself as a 'Windup Alarm and Clock' in her manga free talks. She also draws her two older sisters as clocks, the elder being an antique clock and the younger being a different model alarm clock.
Hari Tokeino is her pen name. She reveals in one of the volumes that it means "Hand of the Clock", thus her reason to draw herself as a clock. She goes on to say that every now and then she regrets choosing that as her pen name.
Her current work is Gakuen Babysitters which is serializing in LaLa.
