The Lost Heir
When a clan with blood relations to the Senju arrive in Konoha, the ninja and civilians are all excited. The Senju were regarded as close to royal with the famed clan which used to reside in Uzushiogakure prior to its destruction. With a chance to finally rub shoulders with royalty, people lined the streets just to meet the clan head, Mito Uzumaki, named after the Shodai Hokage's wife, and sister to the deceased Kushina Uzumaki. There were even rumours of a missing clan heir found, the only child of Mito's sister.
However, the village is in for a shock, when they realise that the Uzumaki clan of Uzushiogakure no sato are less than pleased with the Konoha citizens for reasons they do not explain until they find the missing heir.
