Yuzuki Hanabira

Yuzuki Hanabira is a kunoichi of Konoha. She's apart of the Hanabira clan which is famed for their Kekkei Genkai, those of their clan aren't known to be very powerful but Yuzuki wants to be the one to make her clan stronger as a whole. She's on a team with Satori Uchiha and Kento Hyuga. Yuzuki later in the story awakens a sage mode unique to her clan. She finds out that awakening it is extremely rare, so rare that other clans don't even know it exists. Only the hanabira clan knowing it.

She awakens this flower sage mode after being gifted some 9 tails chakra by Naruto. According to Yuzuki, the Hanabira clan was related to the Senju clan, and a long time ago the clan used to have many members who had the sage mode, but the clan started dying out, they began repopulating the clan by allying with others, slowly the sage mode became less known about, and they all lost the chakra they inherited from the senju clan.

In the 4th great ninja war, satori shares the chakra of the 4 tails, powering up her flower sage mode, so much to the point where her sage modes power itself rivals Hashirama's sage mode. She ends up dying, being targetted by Madara to absorb her nature energy.
