Among the FansEdit
KonoHana is a fairly known crack pairing in the Naruto fandom and even has its own group in devianART. Some NaruHina shippers refer to the shipping, because Konohamaru is Naruto's "younger brother", while Hanabi is Hinata's younger sister. It is also popular for people who don't ship NaruHina, but still think the two may work out together. Their rival pairings are KonoMoegi and any other couples that includes the two characters individually.
