I've received some messages both on my sarahah and tumblr about Rinne's family (especially his daughter) so imma make a special post of them!
● AYAKA SAKURAGI ●
The only daughter of Rinne and Nazuna. She is one of Konohamaru's classmate. Ayaka loves sweets and candies a lot, that Rinne used to spoil her a lot and treat her with it. Since she was a child, she already introduced to Rinne's RGB Team. She sees them as older siblings and they get close as they grow up together. Later during The Last, Ayaka was seen to be trained by Hotaka who inherited her father's signature fighting style. In Boruto, Ayaka assigned to be a supervisor / sensei of 3 man team as her father did.
● NAZUNA SAKURAGI ●
A medic nin, specialized as a surgeon in Konoha Hospital. A calm, gentle doctor who handles her patients with care. During her youth, Nazuna used to treat Rinne as he often got hospitalized after missions and training. Not knowing what kind of battles he went through, Nazuna continued taking care of him until one day Rinne confessed to her. Nazuna wasn't really confident about her age that considered to be "too old to get married" / "old virgin". But she married Rinne at the age 32.
