Soul Society arc
Hironari shows up when Shibata appears before Sado Yasutora after Ichigo Kurosaki and his group try to enter Seireitei by the gate entrance guarded by Jidanbō Ikkanzaka. When Shibata, being carried around by Sado, mentions he has a very nice family to take care of him, Hironari, appearing, tells Shibata it is time for him to go home, or their "mother" and "father" will worry. Slightly confused at Shibata's mentioning of having a family and the appearance of this person, Sado is confused when Shibata, introducing Hironari, describes him as being a "big brother", as the two have different surnames. Hironari explains to Sado Rukongai is composed mostly of family-like groups formed by non-blood related souls. He further explains Rukongai is filled with many people who died at different times and places, so it is rare to be reunited with family members who died earlier. When Sado asks if the Shinigami help with reuniting family members if they die at the same time, Hironari tells him this is not the case, as the procedure for living in Rukongai is one gets a ticket, based on the time they died, and is sent off in different directions. Thus, even if one dies together with one's family, one will not be be able know where the others are if they do not get tickets together at the same time. Hironari surprises Sado by revealing how old he is, as he died in Yamanashi Prefecture. Hironari looks on in a consoling manner as Sado tells Shibata he will meet his mother again if he keeps looking.
