Hana is the mother of Chitoge who visits (albeit very rarely) Chitoge and her husband around Christmas Eve and is also the person who gave Chitoge her red ribbon. Chitoge and her mother had a close relationship with each other when she was younger until Hana started to be engrossed in her work. Sooner or later, Chitoge stopped calling her 'Mom' in front of her and becomes afraid and nervous of her whenever she visits. Hana has always asked Chitoge how old she is (even if she already knows) and never gives her presents. When Hana returns to Japan a few days before Christmas Eve, Chitoge introduces Raku as her boyfriend but as Hana looks at Chitoge's ribbon she asks her why she still wears it due to its frayed condition and tells her to wear something else in order to maintain her appearance
