Shima

is the wife of Fukasaku and an elder toad from Myōbokuzan. As the heirs of the Great Toad Sage, she and her husband are revered as the Two Great Sage Toads. Together with Fukasaku, she taught Jiraiya how to use Senjutsu.

Personality
Shima is considered open-hearted and her personality allows her to see everything with great clarity. Because of this, she adored by all toads as the. She is greatly respected because of her old age and wisdom, but she still manages to bicker with her husband over small things like missing dinner. Despite this constant bickering, she loves Fukasaku very much, calling him as is common among Japanese wives. She was heartbroken when she found Fukasaku killed by Pain. Although highly respected, she herself seems to be lacking respect somewhat, most evident in her calling the Great Toad Sage a senile old man.

Shima seemed to have been fond of Jiraiya and similarly was very welcoming to his pupil, Naruto, when he first went to Myōbokuzan to train, 'pulling out all the stops' at her and Fukasaku's home. During the Battle of Konoha, after Pain had stabbed Fukasaku and pinned Naruto to the ground through his hands, Shima called to Naruto not to give up since both Jiraya and Fukasaku had given their lives because they believed in Naruto, and, if he gave up then, she'd never forgive him.

Abilities
Shima is known for her keen analyses of the situations and circumstances of the battles she participates in. She can quickly figure out the best plan and will turn into the control centre that will make sure that plan is executed. She also has excellent sensing skill, apparently because of her tongue, which allow her to detect and apprehend her enemy with ease. The warts on her tongue can release a highly corrosive mucus.

She has control over at least two elements, which she uses frequently in battle. However, her greatest weapon is her mastery of Senjutsu. She uses this to increase the power and range of her attacks and to push her body to the limits, for instance extending her tongue until it's more than ten metres long.

Of special note are her genjutsu skills. Together with her husband she can perform the Demonic Illusion: Toad Confrontation Singing, a feat only possible because of the harmony the husband and wife developed after centuries of marriage.

Hunt for Itachi arc
Jiraiya summoned Shima and Fukasaku during his fight with Pain to help him enter Sage Mode. In addition to sitting on his shoulders to provide him with natural energy, they gave him advice, and attacked Pain when necessary. Their combined efforts were enough to combat three of Pain's bodies on equal terms. Shima and Fukasaku then created a genjutsu that allowed them to kill the three bodies, but they were soon overwhelmed by the appearance of three more.

Knowing the battle was lost, Jiraiya had Shima take the Animal Path he had captured back to Konoha while he and Fukasaku made one final investigation.

Invasion of Pain arc
While Naruto learns senjutsu from Fukasaku, Shima happily provides him with meals (unaware that her choice of food makes him sick). While restocking her supplies near Konoha, Shima noticed that something was wrong in the village. She summoned Naruto, Fukasaku, Gamaken, Gamabunta, Gamakichi, and Gamahiro to Konoha's center moments after Pain destroyed the village. As Naruto engaged Pain, Shima and Fukasaku provided assistance, dealing with the Animal Path's summons. They were amazed by his perfected Wind Release: Rasenshuriken, something he had not shown them during his training, but were again forced to deal with the Animal Path.

Knowing that the Animal Path must be gotten rid of, Shima coated the area in a dust cloud while Fukasaku threw Gamabunta at the path, giving Naruto an opportunity to finish it off. Pain was soon left with only one body, and Shima and Fukasaku tried once again to use a genjutsu to defeat it. Pain killed Fukasaku and knocks Shima away before they had a chance. Their bodies were later found and Shima, once healed, wept for Fukasaku. When Pain was defeated, and subsequently chose to revive everyone he had killed, Fukasaku was brought back to life, to Shima's shock and surprise. Later, Shima and Fukasaku were both seen together, standing atop Gamakichi's head and watching from a distance as the population of Konoha welcomed Naruto back.
