Enra

is a personal summon of Konohamaru Sarutobi.

Personality
Enra has a somewhat immature attitude, complaining to Konohamaru about the situation and talking a lot. He shows strong team-work and loyalty towards Konohamaru.

Appearance
Enra is a small white monkey with black-markings around his eyes. He wears a yellow, sleeveless kimono-shirt with white fur trimmings and mesh armour underneath, secured with a red belt and black wristbands. He also wears a black bandanna with a Konoha forehead protector on it and has a tuft of hair styled in a ponytail sticking out from behind it.

Abilities
Enra is very quick and agile, able to skillfully evade enemy attacks. He can transform into a staff. Upon transforming, Enra can be wielded by his summoner, becoming a perfect team for attacks. He can also perform fūinjutsu in unison with his summoner.

Konohamaru Arc
When Konohamaru was forced to battle the memory-stealing demon Sōma, Konohamaru summoned Enra to aid him. Enra quickly transformed into a staff. Together, with the aid of Boruto Uzumaki applying special sealing tags, Enra and Konohamaru attempted to seal away the demon with the Adamantine Seal: Monkey Yang Suppression. The demon, however, proved too strong as the duo quickly tired and were repelled, forcing Enra to disperse away.

Video Games
Enra appears in the Naruto Mobile as a support for Konohamaru Sarutobi. During his battles, he runs around the battlefield, arranging mean things like throwing a banana peel at the enemy's feet. When Konohamaru needs it, Enra transforms into a staff and assists him in battle.

Trivia

 * Enra bears many similarities to Enma. They are both talking monkeys, wear similar kimono-shirts (though Enra's lacks tiger stripes), are the only two known users of Transformation: Adamantine Staff, and are summoned by members of the Sarutobi Clan.
