¿What Is Love? (Tobirama's Love Story)
Everything changed when I met you, if it wasn't for you I'd probably be dead.
Yuki Uzumaki, the younger sister of Mito Uzumaki, is sent to the hidden leaf in order to live a life close to her sister. On her way to the village she is attacked by shinobi of the hidden cloud, who wants her for unknown reasons. She is able to defeat the enemy, but is severally injured. Tobirama, who suddenly felt a powerful chakra, went to figure out the source of it, finding our injured young Uzumaki and taking her to the hidden leaf before she died of blood loss.
