Hotaru Uchiha

Hotaru Uchiha (うちはほたる, Uchiha Hotaru) is a kunoichi from the Tsuchigumo Village and a member of the Tsuchigumo clan.

Background
Hotaru is the granddaughter of the former leader of the Tsuchigumo clan, En no Gyōja. She met Utakata after he saved her from a group of ninja who were actually after him. During the battle, Utakata was wounded and collapsed after it. Hotaru ran to her fort to get help to save Utakata. After he was healed, Hotaru asked him to become her teacher, to which Utakata wasn't happy about. Utakata reluctantly begins to teach her by standing on water first, believing that she wouldn't master it. In the morning, she shows that she was able to stand on top of the water by training all night. Next, Utakata taught her Water Release: Wild Water Wave, once again believing that she would not be able to master it without water-nature chakra only to discover she possessed water-nature chakra.

Personality
Hotaru is shown to be a determined individual, as she asked for the kinjutsu to be implanted on her back in order to continue the legacy of her clan and she is somewhat independent as she initially declined help from Naruto. She is also persistent about her goal, endlessly practising techniques taught to her by Utakata until she held basic mastery of them.

Appearence
Hotaru is a young woman with dark-green eyes, a widow's peak, and blonde wavy hair that goes past her shoulders. She wears a light-violet and white top, black shorts, a black skirt, black high boots and light violet wristbands. She is rather short, as shown when standing in front of Naruto.

Abilities
While only trained in some basics of ninjutsu from her grandfather and Tonbee, Hotaru has shown to have a natural talent for the art. During Utakata's repeated attempts to make her give up on training under him, he ordered her to first master some basics in chakra control and techniques. In a short amount of time, without any real instruction, she was able to succeed in them. She is also shown to have an affinity towards water-chakra, much to Utakata Uzumaki's dismay. Under Utakata's "tutelage", she learned how to use the Water Release: Wild Water Wave.

Izumo Arc
When a group of ninja came looking for the Tsuchigumo clan's kinjutsu, Tonbee had Hotaru, along with Utakata, take the clan's kinjutsu so that ninja could not retrieve it. While travelling, Utakata got upset at Hotaru for calling him master (師匠, shishō), at which point Naruto no Mikoto arrived, believing Utakata to be attacking Hotaru. Hotaru broke up the fight and Utakata left her, deciding that the Kami would be capable in protecting her. As she watched him float away in a bubble, she tried to convince him not to leave, but was unsuccessful in doing so. When the Yamata Orochi Emerged from it's Lair and drunk the Rice Wine, Hotaru was heartbroken, thinking that she saw the Bones of Utakata, Unfortunately she saw the Bones of the T-Rex eating Utakata in the Izumo History Museum. She then resolved to allow herself to die with Kushinada Haruno and get save by Susanoo Uzumaki unable to bear the thought that she had betrayed Utakata. As Shiranami fled when the kinjustu absorbed more chakra than it should, Susanoo went after him and left Utakata to save her. He succeeded as Naruto returned, reuniting with his friends. Later, Hotaru and Utakata leave for training.
