Hikari has been present in Old Home for about four years, making her one of the longest-standing residents after Reki and Nemu. Despite sometimes acting impulsively, Hikari is a kind person. When she discovered that she was going to create a halo for Rakka using a mold, she came up with an idea to pour dough into it to make halo-shaped pastries. This is why the little ones believe that Rakka smells like cake. As a result of her creativity, Hikari works at a bakery in town. Although she is modest about her accomplishments, her colleagues appreciate her contributions and do not mind when her friends stop by to enjoy some treats while visiting her. Despite her occasional mischievous behavior, Hikari always has good intentions and is the first to offer assistance.
